System Overview

Overview

The KA49 CPU module combines with either the 4-MB or 16-MB
(or both) SIM modules to form the CPU/memory subsystem for
the VAXstation 4000 Model 90 product. The VAXstation 4000
Model 90 system is housed in a BA46 enclosure. The subsystem
uses the SCSI-1 bus to communicate with mass storage devices,
and transceiver cable (Thickwire or ThinWire connector) to
connect with an Ethernet network. A 16-bit programmed I/O port
connection is available to attach synchronous communications
or other options. An optional bus adapter can be connected to
the module using one of the 32-bit CDAL buses. Four serial
lines are supported for a keyboard, pointing device, printer,
and asynchronous communication. Audio input and output is
supported through the sound generator interface. The KA49 CPU
module supports low cost graphics using the LCSPX module or
high performance graphics using the SPXg/gt modules.

Main Memory

The KA49 CPU module can support up to eight memory SIM
modules to provide main memory configurations of 16, 32, 64, 80,
or 128 MB.

Cache Memory

The module uses multiple levels of cache memory to maximize
performance. The NVAX CPU contains a 2-KB virtual instruction
cache (VIC) and an 8-KB write-through primary cache (Pcache).
The KA49 module contains an on board 256-KB backup write
secondary cache (Bcache).

Central Processor Unit, Continued
Central
Processing
Subsystem

The NVAX CPU (DC246) chip is the heart of the KA49 CPU
module. It executes the VAX base instruction group as defined
in the VAX Architecture Reference Manual plus the optional VAX
vector instructions and the virtual machine instructions. The
NVAX processor also supports full VAX memory management with
demand paging and a 4-gigabyte virtual address space.

Three Level
Cache
Architecture

The KA49 CPU module uses a three-level cache architecture to
maximize performance. The first level of cache, referred to as
the virtual instruction cache (VIC), is 2 KB in size, and is located
on the CPU chip. This cache handles instructions only (no data
references), and deals only with virtual addresses. In this way
the CPU can obtain instruction information without the need for
virtual to physical address translation, thereby decreasing latency
and improving performance.
The second level of cache, referred to as the primary cache
(Pcache), is 8 KB in size and is located on the CPU chip. This
cache implements a write-through instruction and data cache, and
helps to reduce latency on access to data and instructions that are
not found in the VIC. The Pcache uses physical addresses.
The third level of cache, referred to as the backup write cache
(Bcache) is 256 KB. The Bcache is controlled by the Bcache
controller located in the CPU chip. The data and tag store
memory for this cache is located in SRAM chips on the KA49
CPU module. The Bcache uses physical addresses.

Graphics
Subsystem

The graphics subsystem consists of either the LCSPX for low cost
graphics support or the SPXg/gt modules, which support high
performance graphics. Two connectors are provided on the module
that provide a unique interface to each.

Central Processor Unit, Continued
System
Support
Subsystem

The system support subsystem handles the basic functions
required to support the console in a system environment. This
subsystem contains the firmware ROMs, the firmware ROM
controller, the configuration register, and the station address
ROM.
Resident firmware ROM is located on four chips, each 128 KB by
8 bits of programmable FLASH EPROM1 , for a total of 512 KB of
ROM. The firmware gains control when the CPU halts.

ROM Firmware

ROM firmware provides the following services:
Board initialization
Power-up self-testing of the KA49 module
Emulation of a subset of the VAX standard console (auto
or manual bootstrap, auto or manual restart, and a simple
command language for examining or altering the state of the
processor)
Booting from supported Ethernet or SCSI devices
Multilingual translation of key system messages

Configuration
Register

The configuration register allows the firmware and the operating
system to read KA49 configuration bits. These bits indicate which
options are present and the size of the physical memory.

I/O Subsystem

The I/O subsystem contains the following:
CP-Bus adapter
SCSI mass storage interface
Ethernet interface
Optional bus adapter interface
Optional synchronous communication interface
1 A FLASH EPROM is a programmable read-only memory that uses electrical (bulk)
erasure rather than ultraviolet erasure.

NVAX CP-Bus
Bus Adapter

To provide buffering and connection to the I/O devices, the KA49
contains a DC243, NDAL to CDAL adapter (NCA). The NCA
provides an interface between the NVAX NDAL bus and two CPBuses where the I/O device adapters reside. As a bus adapter, the
NCA controls transactions between the higher performance NDAL
bus and the lower performance CP-Buses. Each of the NCA’s
CP-Bus ports provide a CVAX compatible peripheral bus for direct
memory access (DMA) by peripheral devices.

Small
Computer
Systems
Interface

NCR 53C94 implements the small computer system interface
(SCSI) bus interface. It has a single port, connecting both to
devices within the BA46 system box and allowing for expansion
externally.

Ethernet
Interface

The Ethernet interface handles communications between the CPU
module and other nodes on the Ethernet. It is implemented with
the second generation Ethernet controller chip (SGEC) onboard
network interface. Used in connection with the module backpanel,
the SGEC allows the KA49 to connect to either a ThinWire or
standard Ethernet. It supports the Ethernet data link layer and
provides CP-Bus parity protection.

Optional
Bus Adapter
Interface

The optional bus adapter provides a translation between one of
the CP-Buses and the adapter bus. The VAXstation 4000 Model
90 has direct, transparent access to the bus adapter. The slot
appears as a region of memory in the workstation’s I/O space.
The bus adapter option can perform DMA to any location in the
memory space of the VAXstation 4000 Model 90. This DMA can be
done either directly to the physical memory of the workstation or
Continued on next page

1–9

Central Processor Unit, Continued
through a scatter/gather map that allows physically discontiguous
pages of data to appear to be contiguous to the bus adapter option.

Sound
Generator

Sound output uses the DTMF tone generation capability of
the 79C30 chip. Two tone generators may be individually
programmed for frequency and amplitude; their outputs appear
summed using either the loudspeaker integral to the system
unit, or to headphones, or an external loudspeaker if plugged
in to the jack at the front of the machine. The resolution of the
frequency generators is eight bits, giving a frequency range of 8
Hz to approximately 2 kHz.

Serial Line
Controller

The VAXstation 4000 Model 90 system board serial line controller
handles four asynchronous serial lines. The controller consists of
the DC7085 QUART and a 64 entry FIFO RAM shared by all four
receive lines.

Time-Of-Year
Clock

The time-of-year (TOY) clock consists of an MC146818BM CMOS
watch chip that keeps the date and time of day and contains 50
bytes of general purpose RAM storage. This chip includes a time
base oscillator and a lithium battery on-chip. The battery powers
the chip logic and oscillator while the system power is off.

Station
Address ROM

A 32-byte ROM on the system board contains a unique network
address for each system. This ROM is installed in a socket so it
can be moved in the event that a system’s CPU board is replaced.

Memory
Control
Subsystem

The memory control subsystem provides support for the KA49
memory subsystem. A key feature of the KA49 memory
subsystem is the use of ownership bits to maintain a sense
of ownership over each hexaword (32 bytes) of main memory.
This ownership mechanism serves the dual function of
maintaining coherency between main memory and the NVAX

Continued on next page

1–10

Central Processor Unit, Continued
cache memory, as well as providing a secure interlock mechanism
for synchronization between NVAX and the I/O devices.
The memory controller is implemented by the NVAX memory
controller chip (DC244). The NMC is an ECC protected memory
controller. The NMC controls transactions between the main
memory and the NVAX, and between main memory and any of
the I/O devices (through the NCA interface). In addition, the
NMC has a key role in maintaining main memory coherency with
the NVAX Pcache and Bcache through the use of ownership bits.
The NMC interfaces the NVAX and I/O subsystem to up to 128
MB of main memory. Main memory is comprised of one or two
sets of SIM modules. Each set contains either four 4-MB SIM
modules or four 16-MB SIM modules. The NMC controls access to
shared memory locations through the use of the ownership bits,
thereby providing a reliable interlock mechanism for memory that
is shared between the NVAX and the I/O devices.

NVAX
Data/Address
Lines

In order to maximize the bandwidth of the bus connecting the
CPU to the memory and I/O controllers, the NVAX chip set
(NVAX, NMC, NCA) communicates over a "pended" bus called the
NDAL. The main feature of this bus is that devices requesting
read data do not tie up the bus while waiting for the return data.
Rather, a device issues one of the "read" commands on the NDAL
and then relinquishes control of the bus to other devices. This is
so other transactions can be performed while the responder to the
first device prepares to send back the data associated with the
read request. Because of the pended nature of the bus, the NDAL
bus command set includes separate transactions for returning
data from an earlier read cycle.

Processor
State

The processor state consists of that portion of the state of a
process that is stored in processor registers rather than in
memory. The processor state is composed of 16 general purpose
registers (GPRs), the processor status longword (PSL), and the
internal processor registers (IPRs).

Continued on next page

1–11

Central Processor Unit, Continued
Non-privileged software can access the GPRs and the processor
status word (bits <15:00> of the PSL). The IPRs and bits <31:16>
of the PSL can only be accessed by privileged software. The
IPRs are explicitly accessible only by the move-to-processor
register (MTPR) and the move-from-processor register (MFPR)
instructions which can be executed only while running in kernel
mode.
The KA49 implements 16 GPRs, as defined in the VAX
Architecture Reference Manual. These registers are used for
temporary storage, accumulators, and base and index registers
for addressing. These registers are denoted R0 - R15. The bits
of a register are numbered from the right <0> through <31>.
Table 1–2 describes the registers.

Registers

The internal processor registers (IPRs) that are implemented by
the KA49 CPU chip, and those that are required of the system
environment, are logically divided into five groups, as follows:
Normal—Those IPRs that address individual registers in the
KA49 CPU chip or system environment
Bcache Tag IPRs—The read-write block of IPRs that allow
direct access to the Bcache tags
Bcache Deallocate IPRs—The write-only block of IPRs by
which a Bcache block may be deallocated
Pcache Tag IPRs—The read-write block of IPRs that allow
direct access to the Pcache tags
Pcache Data Parity IPRs—The read-write block of IPRs that
allow direct access to the Pcache data parity bits

Interrupts and Exceptions

Overview

Both interrupts and exceptions divert execution from the normal
flow of control. An interrupt is caused by some activity outside the
current process and typically transfers control outside the process
(for example, an interrupt from an external hardware device). An
exception is caused by the execution of the current instruction
and is typically handled by the current process (for example, an
arithmetic overflow).

Nonmaskable
Interrupts

Interrupts can be divided into two classes: nonmaskable and
maskable. Nonmaskable interrupts cause a halt by way of the
hardware halt procedure. The hardware halt procedure does the
following:
Saves the PC, PSL, MAPEN<0> and a halt code in IPRs
Raises the processor IPL to 1F
Passes control to the resident firmware
The firmware dispatches the interrupt to the appropriate service
routine based on the halt code and hardware event indicators.
Nonmaskable interrupts cannot be blocked by raising the
processor IPL.

Maskable
Interrupts

Maskable interrupts cause the following:
The PC and PSL are saved.
The processor IPL is raised to the priority level of the
interrupt.
The interrupt is dispatched to the appropriate service routine
through the system control block (SCB).

Interrupts and Exceptions, Continued
Trap
Exceptions

A trap is an exception that occurs at the end of the instruction
that caused the exception. Therefore, the PC saved on the stack is
the address of the next instruction that would normally have been
executed.

Fault
Exceptions

A fault is an exception that occurs during an instruction and that
leaves the registers and memory in a consistent state such that
elimination of the fault condition and restarting the instruction
will give correct results. After the instruction faults, the PC saved
on the stack points to the instruction that faulted.

Abort
Exceptions

An abort is an exception that occurs during an instruction.
An abort leaves the value of registers and memory
UNPREDICTABLE such that the instruction cannot necessarily
be correctly restarted, completed, simulated, or undone. In most
instances, the NVAX microcode attempts to convert an abort into
a fault by restoring the state that was present at the start of the
instruction that caused the abort.

1–19

Cache Memory

Overview

The NVAX memory subsystem follows a hierarchical structure.
The VIC, Pcache, Bcache, and finally the main memory form the
hierarchical memory subsystem of the KA49. The hierarchical
ordering of the various levels of KA49 memory is shown in
Figure 1–3. For I-stream references, the memory hierarchy
starts with the VIC, whereas for D-stream references the memory
hierarchy starts with the Pcache.
Figure 1–3 KA49 Cache/Memory Hierarchy

Mass Storage
Main Memory
Backup Cache 256 KB
Primary Cache 8KB
VIC 2KB
LJ-01817-TI0

References generated by the NVAX CPU are issued to the memory
subsystem at the first hierarchical level, as determined by the
reference type (I-stream or D-stream). The reference then passes
up through the hierarchy until it is serviced by one of the layers.
References that are serviced at lower layers take less time than
references that must pass to higher layers. For this reason, it is
the intent of the memory subsystem to service most references
within the lower layers, thus maximizing system performance.
By creating successively faster layers of memory hierarchy below
the main memory, the KA49 decreases the average amount
of time required to access information. Because each layer in
the hierarchy tends to be smaller in size than the next higher
(slower) layer, there is the problem of allocating space at each
Continued on next page

1–20

Cache Memory, Continued
layer for storing references. Furthermore, care must be taken to
ensure that the state of the system is singularly and accurately
represented by the combined contents of the caches and main
memory.
In the KA49 this issue is most critical between main memory and
the Bcache and Pcache, because main memory can be accessed
by DMA devices as well as the NVAX CPU. Furthermore, this
problem is complicated by the writeback nature of the Bcache.
This write-back mechanism, while significantly decreasing
the latency of write operations, complicates the problem of
maintaining a coherent and consistent representation of main
memory in the face of DMA traffic.

Cached
References

Any reference that can be stored by the VIC, the Pcache, or the
Bcache is called a cached reference. The Pcache and Bcache store
CPU read references to the VAX memory space (bit <29> of the
physical address = 0) only. They do not store references to the
VAX I/O space.
Whenever the CPU generates a non-cached reference, or a cached
reference not stored in any of the three caches, a single hexaword
reference of the same type is generated on the NDAL Bus.
Whenever the CPU generates a cached reference that is stored in
one of the caches, no reference is generated on the NDAL Bus.

Virtual
Instruction
Cache

Before any instruction can be executed, it must first be fetched
from memory. The NVAX CPU contains an instruction prefetcher
that fetches sequential instructions ahead of the instruction
currently being executed. This is done in an attempt to reduce
the effective access time of the instruction fetch by pipelining it
with decode and instruction execution. The instruction prefetcher
maintains an instruction prefetch queue (IPQ) of up to 16 bytes
(4 longwords) of I-stream data. In order to fill the IPQ, the
prefetcher sends I-stream read requests to the Virtual Instruction
Cache (VIC).

Continued on next page

1–21

Cache Memory, Continued
The VIC is a 2-KB, direct-mapped cache for caching I-stream
data. The VIC is located within the NVAX CPU chip. In order to
reduce the overhead associated with virtual-to-physical address
translation, the VIC caches references based on virtual addresses.
In the event that the virtual references made by the instruction
prefetcher hit in the VIC, the I-stream data is loaded from the
VIC directly to the IPQ.
If the references made by the instruction prefetcher miss in the
VIC, then the VIC issues an I-stream read request on behalf of
the instruction prefetcher to the next level of memory hierarchy,
the Pcache.

Primary Cache

The primary cache (Pcache) is a two-way set associative, read
allocate, no-write allocate, write through, physical address cache
of I-stream and D-stream data. It stores 8192 bytes (8K) of data
and 256 tags corresponding to 256 hexaword blocks (1 hexaword =
32 bytes). Each tag is 20 bits wide corresponding to bits <31:12>
of the physical address.
There are four quadword subblocks per block with a valid bit
associated with each subblock. The access size for both Pcache
reads and writes is one quadword. Byte parity is maintained
for each byte of data (32 bits per block). One bit of parity is
maintained for every tag. The Pcache has a one cycle access and
a one cycle repetition rate for both reads and writes.
The Pcache represents the first level of D-stream memory
hierarchy and the second level of I-stream memory hierarchy in
all NVAX computer systems. Pcache entries must be invalidated
in order to maintain cache coherency with higher levels of the
memory hierarchy.
The Pcache is located within the NVAX CPU chip. Unlike the
VIC, the Pcache is based on physical addresses rather than
virtual addresses. The Pcache handles I-stream requests from
the VIC, as well as D-stream requests for instruction operands.
The Pcache uses a write-through scheme for handling writes to
memory locations which are contained in the Pcache. In this

Continued on next page

1–22

Cache Memory, Continued
scheme, the write operation updates the contents of the Pcache,
and the write operation is propagated to the next level of memory
hierarchy, the Bcache. The Pcache is maintained as a strict subset
of the Bcache.

Backup Cache

The backup cache (Bcache) is direct-mapped, with quadword
access size, and a hexaword (32 bytes) block size. The Bcache
allocates on reads and writes, and uses a write-back protocol.
Bcache tags and cache data are stored in static RAMs that reside
on the CPU module. The NVAX CPU implements the control for
the Bcache tags and data.
The Bcache and Pcache communicate internally to the NVAX CPU
in such a way as to maintain the Pcache as a strict subset of the
Bcache. This is done through the use of "invalidate" commands
sent automatically from the Bcache to the Pcache whenever the
Bcache must invalidate a block. The Bcache invalidates a block in
response to DMA activity to the corresponding memory location,
or to make room in the cache for new data. In the case of Bcache
blocks that contain data for NVAX-owned memory locations, the
process of invalidating the block involves a write-back of the data
contained in the cache to the corresponding memory location. The
write-back operation simultaneously relinquishes ownership of
the hexaword.

1–23

Main Memory System

Overview

The main memory system is implemented in the NVAX memory
controller chip (NMC). The NMC communicates with SIM modules
over the NVAX memory interconnect (NMI). Up to eight SIM
modules are supported, for a maximum of 128 MB of main
memory.
The NMC serves as an interface between the NDAL and NVAX
memory interconnect. The NMI is comprised of the set of signals
leading from the NMC to the memory modules, and provides a
64-bit path to the memory modules. The arbiter for the NDAL is
also built into the NMC.

NVAX Memory
Subsystem

The NMC controls and passes data to or from, one or two sets
of SIM modules using a bank interleaved memory access. It
responds to commands from the CPU and the I/O adapter (NCA).
The NMC is never a commander on the NDAL.
Each set of memory modules can have either zero or four SIM
modules. The memory modules can be either 4 MB (1-MB
DRAMs) or 16 MB (4-MB DRAMs). The SIM modules in each
set must be homogenous (no mixing of 4-MB and 16-MB SIM
modules within a set) although the types of SIM modules can
differ between the two sets (for example, a set of 4-MB SIM
modules and a set of 16-MB SIM modules). The minimum
configuration is 16 MB. Each SIM module consists of fast page
mode 100 ns RAS access time DRAMs.

ROM Memory

Overview

The system board ROM contains processor restart, diagnostic and
console code, and the primary bootstrap program. Another small
ROM is uniquely programmed for each system with its network
address.

System Board
ROM

The system board ROM contains four 128 KB x 8 FLASH ROM
chips that collectively hold 512 KB of data. ROM data appears at
physical addresses 2004.0000 through 200B.FFFF. The data path
to this ROM is 32 bits wide. Certain physical addresses in the
ROM have fixed uses. These fixed uses are listed in Table 1–5.
Table 1–5 ROM Fixed Uses

Network
Address ROM

2004.0000

Processor restart address. The processor begins
execution at this address in non-mapped mode
when a processor restart occurs.

2004.0004

System type register SYS_TYPE. The contents of
this longword supplement the internal processor
SID register to identify the processor and system
type.

A 32-byte ROM on the system board contains a unique network
address for each system. Data from this ROM is read in the
low-order bytes of 32 consecutive longwords at physical addresses
2780.0000 through 2780.007C. The network address occupies the
first six bytes (addresses 2780.0000 through 2780.0014). The byte
at 2780.0000 is the first byte to be transmitted or received in an
address field of an Ethernet packet. Its low-order bit (bit 0) is
transmitted or received first in the serial bit stream.
This ROM is installed in a socket so it can be moved in the event
that a system board is replaced.

Graphics Controller

Overview

The VAXstation 4000 Model 90 workstation supports three
graphics options: LCSPX, SPXg, and SPXgt. The LCSPX module
is a low cost graphics module, while the SPXg/gt modules support
high performance 3D graphics. The SPXg is an 8-plane graphics
module and the SPXgt is a 24-plane graphics module. Note
that only one video option can be physically installed into the
workstation at a time. All the graphics options share a single
interrupt request signal and interrupt vector. The graphics
interrupt can be enabled/disabled by a bit in the INT_MSK
register. All of the graphics options can be reset with the graphics
reset bit in the IORESET register. Two bits in the configuration
register allow software to determine if an LCSPX or a SPXg/gt
module is installed in the system.

LCSPX

The LCSPX module is a redesign of the VXT 2000 SPX module.
This is a cost-reduced SPX module that interfaces directly to the
CP2 bus. The LCSPX module is functionally the same as the VXT
2000 SPX module except that two video oscillators are supported
using a module switch. The diagnostic ROM/Configuration
register on the LCSPX module contains information about
the oscillator currently in use. This is the only register that is
different from the VXT 2000 SPX module. Table 1–6 shows the
bit definitions associated with the diagnostic ROM configuration
register.

ROM Data Field

These bits contain the ROM data that represents
the diagnostic code for the video subsystem.

SPXg/gt

The SPXg and SPXgt modules were originally designed to be
installed into an LCG frame buffer connector on the Model 60
system. The DC7201 chip in the Model 60 system provided the
interface to the SPXg/gt graphics module. The DC7201 chip
provided a direct path for the processor to read and write SPXg/gt
registers along with support for DMA into the SPXg/gt FIFO. In
the Model 90 system, no DMA support for SPXg/gt is provided.
The SPXg/gt is accessible using three separate address ranges.
The base address range for SPXg/gt module is 2800.0000 to
29FF.FFFF. In addition, a direct access path to the Brooktree
RAMDAC is supported at addresses 2A00.0000 to 2A00.003C.
Finally the SPXg/gt diagnostic ROM is located at addresses
2A10.0000 to 2A17.FFFF. The diagnostic ROM is accessible a
word at a time on aligned quadword boundaries.

Network Interface Controller

Overview

1–28

The KA49 includes a network interface that is implemented by
the second generation Ethernet controller (SGEC). This interface
allows the KA49 module to be connected to either a ThinWire or
standard Ethernet network and supports the Ethernet data link
layer. The SGEC also supports CP-Bus parity protection.

Serial Line Controller

Overview

The serial line controller handles four asynchronous serial lines.
The DC7085 chip is used as the serial line controller. The DC7085
directly controls an external 64-entry silo shared by all four
receive lines. Access to the DC7085 by the CPU and interrupt
processing for the DC7085 are controlled by the CEAC. The four
serial lines are numbered 0 through 3, and each has a particular
primary use, as described in Table 1–7.

Table 1–7 Serial Line Usage
Line

Device

Description

Keyboard

Connected to a 15-pin D-sub connector1 and to a 4-pin
modular jack mounted on the system board. Data leads
only. Supports the LK401 keyboard.

Pointer

Connected to a 15-pin D-sub connector1 and to a miniature
DIN connector mounted on the system board. Data leads
only. Supports VSXXX-AA mouse or VSXXX-AB tablet.

Communications

Connected to a 25-pin D-sub connector mounted on the
system board, RS423 compatible. Data leads plus modem
control signals.

Printer

Connected to a 6-pin modified modular jack mounted on the
system board. DEC423, data leads only.

1 Same connector

Line 3 is normally connected to a printer through a BC16E cable.
If a switch, accessible from the front of the system enclosure, is
set to enable, a received break condition on this line asserts the
CPU halt signal, which causes a processor restart with a restart
code of 2.

1–29

Time-of-Year Clock

Overview

The time-of-year (TOY) clock consists of an MC146818BM CMOS
watch chip that keeps the date and time of day and contains 50
bytes of general purpose RAM storage. This chip includes a time
base oscillator and a lithium battery on-chip. The battery powers
the chip with logic and oscillator while system power is off.

Battery Backup

A lithium battery within the watch chip supplies power to the
watch chip and its time base oscillator while system power is off.
The battery maintains the clock operation and the data stored in
the 50 bytes of RAM for a minimum of 10 years before it becomes
exhausted.

Watch Chip
Registers

The watch chip contains 64 8-bit registers. Ten of these contain
date and time data, four are control and status registers, and the
remaining 50 provide general purpose RAM storage. The registers
occupy 64 consecutive longwords of address space as shown in the
next table.
Each register is accessed as bits <9:2> of a longword. Bits <31:10>
and <1:0> are ignored on writing and undefined on reading.
WARNING
Because each register spans two bytes on the system
bus, only word or longword access instructions may
be used to manipulate these registers. The effects
of using byte access instructions are undefined. In
particular, instructions for modifying bits such as
BBSS, BBSC, BBCC, and BBCS cannot be used; they
generate byte-access read-modify-write cycles that will
corrupt the portion of the register that is not in the byte
being accessed.

1–30

SCSI Controller

Overview

The SCSI interface is a single-ended, bi-directional, 8-bit-wide bus
to which up to eight devices can be attached. The KA49 system
module is one of those devices, allowing the attachment of up
to seven additional devices. Devices may play one of two roles:
initiator or target. An initiator originates an operation by sending
a command to a specific target. A target performs an operation
that was requested by an initiator. The KA49 module is always
the initiator and all other SCSI devices attached to it are targets.

Connecting
Devices

Each device attached to the SCSI bus is identified by a unique
device ID number in the range 0 through 7. During the
arbitration, selection, and reselection bus phases in which an
initiator and a target establish a connection, the device IDs
of the initiator and target are both placed on the data bus by
asserting the data bits corresponding to the device ID numbers.
By convention, the ID number of the VAXstation Model 90 system
is six (this is controlled by the programs that drive the SCSI
interface; it is not fixed in Model 90 hardware).
The electrical interface consists of 18 signal lines. Some of these
lines are driven only by initiators, some only by targets, and some
by either. The SCSI bus is always terminated at each end. The
bus is permanently terminated at the controller (near end). Far
end termination can take place in one of two locations:
At the expansion connector on the rear of the system
enclosure
At the second expansion connector on a storage expansion
unit

SCSI Bus
Signals

Table 1–8 describes the SCSI bus signals used by the SCSI
controller.

Table 1–8 SCSI Bus Signals
Bus Signal

Description

DB7..0 and DBP

An 8-bit parallel data bus with an associated odd parity bit. The
use of the parity bit is optional but strongly encouraged. These
lines may be driven by either an initiator or a target, depending
upon the direction of data transfer.

RST

Signals all devices on the SCSI bus to reset to their initial poweron states. Thereafter, it should be asserted only as a last resort
during error recovery since it indiscriminately affects all devices on
the bus. An RST signal generated by some other device on the bus
causes an internal reset of the 53C94 chip used in this controller
and sets the interrupt request bit (INT in register SCS_STATUS).

BSY and SEL

Used by initiators and targets during the arbitration, selection,
and reselection bus phases to establish or resume a logical
connection between an initiator and a target. Once the connection
is established, the target asserts BSY and the SEL signal is not
driven..

ATN

Used by an initiator to signal a target that it has a message ready.
The target can receive the message by entering the "message out"
phase. ATN is always driven by an initiator.

REQ and ACK

Used to synchronize information transfers over the data bus during
any of the six information transfer phases. REQ is always driven
by the target, ACK is always driven by the initiator.

C/D, I/O and MSG

Collectively indicate one of six possible information transfer phases.
These signals are always driven by the target device.

DSW21 Synchronous Communications Adapter

Overview

The DSW21 syncrhonous communications adapter is a
synchronous serial communications interface for the VAXstation
4000 Model 90 workstation. It has full modem control and
multiple protocol support. Figure 1–4 shows the DSW21
communications adapter.
Figure 1–4 Synchronous Communications Adapter

MLO-005915

The adapter is an option board that connects internally to the
CPU board by a 64-pin option connector. It consists of the EDAL
interface, 128 KB UVEPROM, 256 KB static RAM, the MC68302
integrated multi-protocol processor (IMP), and I/O receivers and
drivers with static and lightning protection. The communications
I/O connector is a 50-pin D-subminiature plug that goes directly
through the back of the system cabinet. Figure 1–5 shows the
DSW21 connections.

Power-Up Initialization Code

Overview

The power-up initialization code is executed when power is
applied to the VAXstation 4000 Model 90 workstation or any
time volatile console data structures are altered.

Power-Up
Initialization
Sequence

Table 2–1 describes the power-up initialization sequence.

Table 2–1 Power-Up Initialization Sequence

What the System Does

Tests enough memory to bring up the console for building console and device
structures.

Checks its configuration, identifies optional devices, and identifies the type
of monitor connected to the video slot.

Tests the TOY clock and the non-volatile RAM. If this test fails, the power-up
test stops.

Constructs the master configuration table (MCT), device configuration table
(DCT), driver descriptor, shared console interface area (SCIA), and a blank
page frame map.

What the System Does

Test dispatcher tests the functional blocks of the system. This test displays
a blank ruler on the screen. The length of the ruler is dependent on the
devices in the system. The dispatcher runs the tests in the following order:
Non-Volatile RAM (NVR)
Color graphics (LCSPX, SPXg or SPXgt)
Serial line controller (DZ)
Cache memory (SCSI DMA RAM, OBIT RAM, BCACHE)
Memory configuration (MEM)
Floating point unit (FPU)
Interval timer (IT)
Miscellaneous system board (checksums, Ethernet ID ROM) (SYS)
Network controller (NI)
SCSI controller (SCSI)
Sound chip (AUD)
Option board (COMM)
Bus adapter logic
If an error occurs during testing, the dispatcher continues to test the
remaining devices until all tests are completed.
NOTE
If halts are enabled, the console prompt >>> displays.
If not, the system is autobooted using the default
device stored in the NVR or the Ethernet if no device is
specified.

2–4

Console Mode

Overview

The VAXstation 4000 Model 90 console mode allows operation of a
console device, which can be one of the following:
A workstation video device and LK401 keyboard and mouse
A terminal connected to line three of the serial port
A remote system connected using the Ethernet

Console Mode

The console mode can be entered if:
The HALT parameter is set to halt when power is turned on.
A HALT instruction is executed with the HALT action set
to HALT or a severe processor condition occurs (such as an
invalid interrupt stack).
An external HALT is detected (pressing the halt button on
the front panel).

Input and
Output

In console mode input and output (I/O) routines are used by:
Self-Test
Extended self-test
Utilities
System test
Virtual memory boot (VMB)

2–5

Extended Self-Test

Overview

The extended self-tests are started by entering the TEST
command at the console prompt, followed by the test number
or numbers you wish to run. The test dispatcher runs the self-test
requested until an error occurs or until all tests are completed.

Test Dispatcher

The dispatcher uses the main configuration table (MCT), device
configuration table (DCT), and drive descriptor data structures
when running a self-test.
Table 2–2 shows the stages of the test dispatcher self-test
procedure.

Table 2–2 Test Dispatcher Procedure
Stage

What the Dispatcher Does

Uses the device number to index into the MCT.

Receives a pointer to the device DCT from the MCT.

Finds a pointer to the device directory entries in the DCT.

Scans all the directories for a directory type of the self-test directory (=1).

Reads the flags field in the DCT to determine if the self-test diagnostic needs
to be loaded into RAM.
If the diagnostic needs to be loaded into RAM, the dispatcher allocates
memory for loading the diagnostic (moving it from ROM to RAM).

Continued on next page

Extended Self-Test, Continued
Table 2–2 (Continued) Test Dispatcher Procedure
Stage

What the Dispatcher Does

Reads the flags field in the DCT to determine if the diagnostic uses a shared
diagnostic driver.

If...

Then...

The self-test diagnostic
uses a shared
diagnostic driver

The dispatcher gets the directory entry and the
pointer to the driver descriptor from the DCT.

The shared driver
needed is not already
in RAM

The dispatcher allocates temporary RAM for
the shared driver (loading the driver from ROM
to RAM) and fills in the driver descriptor data
structure to point to the RAM based shared driver.

Calls the devices self-test interface.

The console mode passes a list of parameters to the test
dispatcher. The test then uses the main configuration table
(MCT), device configuration table (DCT), and driver descriptor
data structures when running a utility. Table 2–3 describes the
dispatcher process for running a utility.

Table 2–3 Running a Utility Process
Stage

Dispatcher Process

Uses the device number to index into the MCT.

Receives a pointer to the device DCT from the MCT.

Finds a pointer to the device directory entries in the DCT.

Scans all the directories for a directory type of the utility directory (=3)

Reads the flags field in the DCT to determine if the utility needs to be loaded
into RAM.
If the utility needs to be loaded into RAM, the dispatcher allocates memory for
loading the utility (moving it from ROM to RAM).

The dispatcher allocates temporary RAM for the
shared driver (loading the driver from ROM to RAM)
and fills in the driver descriptor data structure in the
driver descriptor for the shared driver.

Calls the utility entry point.

Checks the parameters passed.
If the parameters are out of range or too many passed, the dispatcher sends
out an illegal parameter message.

Prompts the user if more parameters are needed.

Prompts the user if the utility is going to destroy any user data.

Starts the utility.

2–9

System Test

Overview

The system test tests the device interaction in the system by
creating maximum DMA and interrupt activity. The test consists
of:
Modified VAXELN kernel
System test monitor
System diagnostics
Shared drivers (if present)
The system test can be run in three environments, selected by the
SET DIAGENV command.
Customer - 1
Digital Services - 2
Manufacturing - 3
CAUTION
Do not use the manufacturing mode in the field.
Manufacturing mode erases customer data on hard
disks, excluding the system disk.
Refer to Table 5–8 for more detailed information on running the
system test.

Configuration Table

Overview

Information on the VAXstation 4000 Model 90 devices is stored in
the system configuration tables during the power-up initialization.
The initialization code sizes the system by reading the ROM-based
device configuration tables (DCT) and builds a memory resident
configuration data structure. Figure 2–5 shows how the data
structures are linked together.

Main
Configuration
Table

The main configuration table (MCT) contains a list of the devices
in the system and a pointer to the device configuration table
(DCT) for each device. The MCT is built when power is turned on
and resides in the diagnostic area in memory. The MCT gives the
test dispatcher a single interface into the various components of
the system. The MCT is shown in Figure 2–6.

Console Driver Interface

Overview

The Model 90 console code is split into a class/port driver scheme.
The class driver contains the main console functions, such as
PUTCHAR and GETCHAR. The port drivers contain the device
specific code required to support these functions. Figure 2–10
shows the division of the console function.

Performing I/O

The console device can require either one channel or two channels
to perform I/O to the console device. If the console device is a
graphics terminal with a LK401 keyboard, the console program
must interface with the serial line device driver for console input
and interface with the graphics device driver for output from the
console. If the console device is a terminal connected to a serial
Continued on next page

2–31

Console Driver Interface, Continued
line, the console responds to the serial line driver for both input
and output.
The console class driver contains the generic routines that
interface to the console and user application to perform terminal
input and output transactions. The console class driver interfaces
with the port driver depending on the current console device.
If the console port driver does not support PUTCHAR or
GETCHAR functions, it must interface with the appropriate
port driver to perform the needed function.

Shared
Console
Interface Area

The shared console interface area (SCIA) consists of a console
class driver descriptor and three port driver descriptors. The
port driver descriptors can be associated with a DZ port driver, a
graphics output driver, and a network driver.
The SCIA provides an interface to the console terminal that
isolates the implementation specifics of accessing the console
terminal. It is designed so the console drivers can run in both
virtual and physical mode.
The SCIA is set up by the initialization code. After the SCIA is
set up, the software can use this area to interface with the console
class driver routine. The shared console performs the following:
Raw character I/O to console terminal
Higher level of I/O functions that handle XON/XOFF flow
(ASCII bell character and LK401 keyboard translation are
handled by the DZ driver.)
Data structures to allow system software to map all console
code and I/O space references into virtual memory as needed

Alternate Consoles

Description

The Model 90 provides two ways to use alternate consoles if the
graphics subsystem fails. Console commands can be entered
on a terminal connected to the printer/communications port,
communications/printer (RS232) port, or from either Ethernet
(standard, ThinWire) network port. The two alternate consoles
are described in the following sections.

Printer Port
Console

To access the printer/communications port, communications
/printer port console, verify that:
The baud rate of the terminal connected to the printer port is
set at 9600 baud.
The alternate console switch (S3) located on the front panel
is in the up position.
NOTE
The state of the alternate console switch is only read
at power up. Changing the switch setting when the
system is powering up has no effect until the system
box is powered down and then powered up again.

Network
Console

The system console can be accessed from the network. The
network console allows you to remotely troubleshoot the system or
provide a console when the other consoles are not available.
Some console tests and commands cause the network connection
to be terminated because the commands use the network device,
or they cause a connection timeout at the remote node.
To access the console you need:
The hardware Ethernet address of the VAXstation computer.
Access to a VMS operating system on the same Ethernet
segment as the VAXstation 4000 computer (the systems
cannot be separated by a bridge or router).

Continued on next page

4–25

Alternate Consoles, Continued
The following VAXstation 4000 computer parameters must be
set:
—

A console password

Troubleshooting

For the troubleshooting process, it is assumed that problems are
not caused by such things as faulty power cords or loose modules
and connectors.
Actual error codes and their meanings are provided in Appendix
A.

5–2

Diagnostic Functions
The system firmware provides the diagnostic functions listed in
Table 5–1.
Table 5–1 Diagnostic Functions
Function

Description

Power-Up test

Tests initialization and all devices.

Extended self-test

Tests devices in the system sequentially with
the TEST command.

System test

Tests all devices in the system interactively.

Utilities

Provide functions for visual screen test, mass
storage devices, and the network listener.

Error reporting

Displays error messages on the console when
errors are found during power-up tests,
self-tests, and system tests.

5–3

System Power-Up Test

Overview

The system power-up self-test sequentially tests the devices in the
system. This test takes about one minute to complete for a 16-MB
base system. When the test successfully completes, the console
prompt appears. Figure 5–1 shows the prompt.
Factors increasing the test time are:
Additional memory
Maximum memory configurations take approximately seven
minutes to complete the self-test,
Additional time is required for SCSI devices.
The time for the system power-up self-test to execute can be
reduced by setting the FBOOT parameter to 1. The system then
does not test memory on power-up.

Power-Up
Sequence

Figure 5–1 and Figure 5–2 show the console screens that display
when successful and unsuccessful power-up tests occur.
The following events summarize the power-up sequence:
If the system finds a fatal error before initializing the console,
the error can only be decoded using the eight error LEDs
located on the lights and switches board.
Refer to Appendix A. If all of the error LEDs remain on, the
ROM code did not start.
If the graphics subsystem fails self-test, the system assumes
that a console terminal is connected to the console/printer
port.
If the alternate console switch, located on the light and
switches board, is set to alternate console (switch in the
up position), the system assumes that a console terminal is
connected to the console/printer port.

Continued on next page

5–4

System Power-Up Test, Continued
At the end of the power-up sequence the system enters
console mode, as indicated by the >>> prompt, if the HALT
parameter is set to 3. If the HALT parameter is set to 1 or 2,
the system tries to boot the default boot device.
During initialization, the system is configured by creating the
main configuration table (MCT) and the device configuration
table (DCT).

Self-Test Descriptions, Continued
The following tests are included:
Byte Mask test
Checks the byte mask signals that are generated by the CPU.
This test is performed on each page boundary. Once the test
is complete, all free memory is filled with AAh.
Memory test (forward)
Performs a read/compare/complement/write on the memory
in the forward direction. If a page is found to be bad, the
appropriate bit in the memory bitmap is cleared.
Memory test (reverse)
Starts at the last address to be tested and performs a read
/compare/complement/write on memory. If a page is found to
be bad, the appropriate bit in the memory bitmap is cleared.
Final Parity test
Fills all of memory with a pattern of 01h (an odd bit pattern)
to verify that the parity bit can be changed. This pattern is
read and verified. A parity error occurs if the parity bit is
not changed. The pattern 01010101h is the known state of
unused memory after power-up.
Refer to Appendix A for a list of the memory test error codes and
Appendix B for a list of the memory test diagnostic LED codes.

Floating Point
Unit Self-Test

Self-Test Descriptions, Continued
Interval Timer
Self-Test (T 7)

The following test is included:
Interrupt test
Enables the interval timer interrupts. It lowers the IPL for
30 ms and counts the number of interrupts. If there are too
few or too many interrupts, an error occurs.

System
Self-Test (T 8)

The following test is included:
System ROM test
Checks the system ROMs one byte at a time to ensure that
they contain the correct manufacturing check data and the
correct checksum.

Network
Interconnect
Self-Test (T 9)

The NI self-test is for the network interface.
Setup Notes
You must install an external loopback connector or a network
connection (cable) at the selected network port before running a
self-test.
The following tests are included:
Network Address ROM test
Verifies the 32-byte network address ROM, which contains
the unique 6-byte network address along with the 2-byte
checksum and test data byte. It checks for a null or multicast
address, calculates/compares the checksum, and verifies the
test data bytes.
SGEC Register test
Tests the address and data paths to the SGEC register
address port (RAP) and the register data port (RDP) for each
of the four control status registers (CSRs).
SGEC Initialization test

Continued on next page

Self-Test Descriptions, Continued
Sets up the SGEC data structures and initializes the SGEC
chip, which causes the SGEC to perform a single word DMA
read to the system memory.
SGEC Internal Loopback test
Verifies the correct operation of the SGEC transmitter and
receiver during an internal loopback. It also verifies the
burst-mode DMA read and write on non-word-aligned data
buffers for packets of different lengths and data patterns.
SGEC Interrupt test
Enables, forces, and services the SGEC interrupts for
initialization, transmission, and reception using internal
loopback.
SGEC CRC test

SCSI Self-Test
(T 10)

The SCSI self-test is for the SCSI controller.
Setup Notes
CDROM devices fail in extended mode if media is not
installed in removable media drives.
If some or all devices do not show up in the configuration
display after running the test, ensure that all devices have
a unique ID number. Verify that power is supplied to all
devices and the system module. Check to ensure that the
SCSI cable is connected to the system module and devices,
and that the bus is terminated.
All expansion boxes must have power supplied before the
system box is powered up, or the expansion box devices will
not be configured.
Common causes of errors or devices missing from the
configuration include:
—

SCSI bus is not terminated.

—

All device IDs are not unique.

—

Internal cables to the drives are disconnected.

Continued on next page

5–26

Self-Test Descriptions, Continued
The following tests are included:
Register test
Verifies that the 53C94A Controller Chip registers are fully
functional. All read/write bits that can be written are written
to. It also verifies the bits.
Interrupt test
Verifies the SCSI bits in the interrupt mask register,
interrupt request register, and the interrupt clear register. A
SCSI interrupt is forced, with the SCSI bit in the interrupt
mask first set and then cleared. This is repeated for both a
high interrupt priority level and a low priority level.
Data Transfer test
Verifies SCSI bus communication between the controller
and the available peripherals and also the data path of
the controller to the memory. A series of four inquiry
commands are issued to each device. The commands are
issued in the programmed I/O mode, asynchronous mode
with DMA, asynchronous mode with the DMA starting on a
non-word-aligned boundary and crossing a page boundary,
and synchronous mode with DMA.

System Test Environment Configuration

Overview

The system test is a strenuous test of the workstation. All devices
are exercised simultaneously to find system interaction problems.
The system test can be used to find faults that only occur when
the system interaction is high.
The system test can be run in three environments, which you
select with the SET DIAGENV command. Refer to Selecting
a Diagnostic Environment for information on selecting an
environment.
Important points to note about the system test are:
Runs under a modified VAXELN kernel that is loaded from
ROM.
Causes a worst case environment in terms of system
interaction, using maximum DMA and interrupts.

System Test

This section explains the Network Interconnect (NI) System test.
Setup Notes
The selected NI port must be connected to a network, or have
a loopback installed.
A more thorough test is done if the system is connected to a
live network and MOP is enabled.
Maximum testing of hardware occurs on a live network with
MOP enabled.
The network system test tests the network port using external
loopback packets. The packets vary in size from 1 byte of data to
32 bytes of data. The pattern for the packets comes from a set of
8 patterns: AA, 55, 34, CB, 99, 66, 43, and BC.
The following is an example of a network system test error; xxxx
is the error code.

Setup Notes
If some or all devices are not in the summary screen after
running the system test, verify that all devices have unique
ID numbers.
Ensure that the power cable is connected to the devices and
the system module.
Ensure that the SCSI cable is connected to the system and
the devices, and that the SCSI bus is terminated.
When in Digital Services or manufacturing mode, media
must be present in the removable media drives, otherwise an
error occurs.
When in manufacturing mode, removable media must be
write protected when present in the drives, otherwise an
error occurs.
In order for destructive testing to be performed in Digital
Services mode, a key pattern must be on the removable
media disks and tapes.

The following tests are included:
Inquiries test
Performs inquiries to find out which devices are connected to
the SCSI bus.
Size Bus test
Spins up all the hard disk drives, ensures that the drives are
ready (if not in customer mode), forces disk block sizes to 600
bytes, and obtains the capacity of the drives. This test also
verifies that removable media are write protected; that the
key pattern is present on removable media in Digital Services
mode; and that VMS boot block is present on the hard disk
drives when in manufacturing mode.
Data Transfer test
Verifies SCSI bus communication between the controller and
available peripherals. It also verifies the data path of the
controller to the memory.
Device test
Verifies the peripheral devices attached to the SCSI bus, and
the DMA data path. Interrupts are enabled.

NI Utility

The NI utility is invoked by the SET or SHOW commands, not by
the TEST/UTIL command. The NI utility functions are:
SET/SHOW MOP - Enable/Disable NI listener
SET/SHOW TRIGGER - Enable/Disable EBM

NI Listener

The NI listener can send and receive messages while the system
is in console mode. The operation of the NI listener is transparent
to the console, and NI listener errors are not reported. Listener
failure can only be detected with the use of a network monitor
device. The default is NI listener enabled.
Examples:
To enable the listener, type the following:
>>>SET MOP 1

To disable the listener, type the following:
>>>SET MOP 0

EBM

The entity-based module (EBM) is used to enable the remote
console and remote boot. Remote boot allows another system to
send a boot message to the workstation to start the bootloader.
Examples:
To enable the MOP boot type the following:
>>>SET TRIGGER 1

To disable the MOP boot type the following:
>>>SET TRIGGER 0

Notes

Follow these guidelines about the SCSI utilities:
Never run a SCSI utility on the Host ID (ID = 6).
An error mnemonic of SCSI_E_type indicates you cannot
perform the utility on the specified device, for example,
running the tape key utility on a fixed disk.
On the formatter and erase utilities, you must type OK at
the DKAxxx OK prompt, or an error appears.
An error occurs if an invalid device ID and logical unit
number (always 0) are entered. Type SHOW DEVICE from
the console prompt for the correct IDs.
If a drive is not listed in the SHOW DEVICE table, verify the
SCSI and power connections, and ensure that there are no
duplicate device IDs.

Utilities

The MIPS/REX emulator utility executes TURBOchannel option
firmware. The emulator functions as follows:
Each MIPS instruction that would normally be executed by
a MIPS processor passes through the emulator software and
executes.
REX callback routines that would normally be provided by
the DECstation console are either mapped one-to-one to
their VAXstation console equivalents, or support routines
are added where functions differ from those provided in the
VAXstation computer.
Allows the execution of canned tests and utilities for specific

Product Fault Management

Overview

This section describes how errors are handled by the microcode
and software, how the errors are logged, and how, through the
symptom-directed diagnosis (SDD) tool, VAXsimPLUS, errors are
brought to the attention of the user. This section also provides
the service theory used to interpret error logs to isolate the FRU.
Interpreting error logs to isolate the FRU is the primary method
of diagnosis.

General
Exception
and Interrupt
Handling

This section describes the first step of error notification: the
errors are first handled by the microcode and then are dispatched
to the VMS error handler.
The kernel uses the NVAX core chipset: NVAX CPU, NVAX
memory controller (NMC), and NDAL-to-CDAL adapter (NCA).
Internal errors within the NVAX CPU result in machine check
exceptions, through system control block (SCB) vector 004, or soft
error interrupts at interrupt priority level (IPL) 1A, SCB vector
054 hex.
External errors to the NVAX CPU, which are detected by the
NMC NCA, usually result in these chips posting an error
condition to the NVAX CPU. The NVAX CPU then generates a
machine check exception through SCB vector 004, hard error
interrupt, IPL 1D, through SCB vector 060 (hex), or a soft error
interrupt through SCB vector 054.
External errors to the NMC and NCA, which are detected by
chips on the CDAL busses for transactions that originated by the
NVAX CPU, are typically signaled back to the NCA adapter. The
NCA adapter posts an error signal back to the NVAX CPU, which
generates a machine check or high level interrupt.
In the case of direct memory access (DMA) transactions where the
NCA or NMC detects the error, the errors are typically signaled
back to the CDAL-Bus device, but not posted to the NVAX CPU.
In these cases the CDAL-Bus device typically posts a device level
interrupt to the NVAX CPU by way of the NCA. In almost all
cases, the error state is latched by the NMC and NCA. Although
Continued on next page

5–56

Product Fault Management, Continued
these errors do not result in a machine check exception or high
level interrupt (results in device level IPL 14–17 versus error
level IPL 1A, 1D), the VMS machine check handler has a polling
routine that searches for this state at one second intervals. This
results in the host logging a polled error entry.
These conditions cover all of the cases that eventually are handled
by the VMS error handler. The VMS error handler generates
entries that correspond to the machine check exception, hard or
soft error interrupt type, or polled error.

VMS Error
Handling

Upon detection of a machine check exception, hard error interrupt,
soft error interrupt or polled error, VMS performs the following
actions:
Snapshot the state of the kernel.
Disable the caches in most entry points.
Determine if instruction retry is possible if it is a machine
check and if the machine check is recoverable.
Instruction retry is possible if one of the following conditions
is true:
—

If PCSTS <10>PTE_ER = 0:
Verify that (ISTATE2 <07>VR = 1) or (PSL <27> FPD =
1), otherwise crash the system or process depending on
PSL <25:24> Current Mode.

—

If PCSTS <10>PTE_ER = 1:
Verify that (ISTATE2 <07>VR = 1) and (PSL <27>FPD =
0) and (PCSTS <09>PTE_ER_WR = 0), otherwise crash
the system.

ISTATE2 is a longword in the machine check stack frame at
offset (SP)+24; PSL is a longword in the machine check stack
frame at offset (SP)+32; VR is the VAX restart flag; and FPD
is the first part done flag.

Continued on next page

5–57

Product Fault Management, Continued
Determine if the threshold has been exceeded for various
errors (typically the threshold is exceeded if three errors
occur within a 10 minute interval).
If the threshold has been exceeded for a particular type of
cache error, mark a flag that signifies that this resource is to
be disabled (the cache will be disabled in most, but not all,
cases).
Update the SYSTAT software register with results of error
/fault handling.
For memory uncorrectable error correction code (ECC)
errors:
—

If machine check, mark page bad and attempt to replace
page.

—

Fill in MEMCON software register with memory
configuration and error status for use in FRU isolation.

For memory single-bit correctable ECC errors:
—

Fill in corrected read data (CRD) entry FOOTPRINT
with set, bank, and syndrome information for use in
FRU isolation.

—

Update the CRD entry for time, address range, and
count; fill the MEMCON software register with memory
configuration information.

—

Scrub memory location for first occurrence of error
within a particular footprint. If second or more
occurrence within a footprint, mark page bad in hopes
that page will be replaced later. Disable soft error
logging for 10 minutes if threshold is exceeded.

—

Signify that CRD buffer be logged for the following
events: system shutdown (operator shutdown or crash),
hard single-cell address within footprint, multiple
addresses within footprint, memory uncorrectable ECC
error, or CRD buffer full.

For ownership memory correctable ECC error, scrub location.
Log error.

—

Uncorrectable data store ECC errors present in Bcache
for marked as OWNED.

—

Most INT60 errors.

—

Threshold is exceeded (except for cache errors).

—

A few other errors of the sort considered nonrecoverable
are present.

Disable cache(s) permanently if error threshold is exceeded.
Flush and re-enable those caches which have been marked as
good.
Clear the error flags.
Perform return from exception or interrupt (REI) to recover
and restart or continue the instruction stream for the
following situations:
—

Most INT54 errors.

—

Those INT60 and INT54 errors which result in bad ECC
written to a memory location. (These errors can provide
clues that the problem is not memory related.)

—

Machine check conditions where instruction retry is
possible.

—

Memory uncorrectable ECC error where page
replacement is possible and instruction retry is possible.

—

Threshold exceeded (for cache errors only).

—

Return from subroutine (RSB) and return from all polled
errors.

NOTE
The results of the VMS error handler may be preserved
within the operating system session (for example,
disabling a cache) but not across reboots.
Although the system can recover with cache disabled,
the system performance is degraded because access
time increases as available cache decreases.

The VMS error handler maintains a correctable read data (CRD)

for high-level events to the error log file. The CRD buffer and
resultant error log entry are maintained and organized as follows:
Each entry has a subpacket header (Figure 5–14) consisting
of LOGGING REASON, PAGE MAPOUT CNT, MEMCON,
VALID ENTRY CNT, and CURRENT ENTRY. MEMCON
contains memory configuration information, but no error

Each memory CRD entry represents one unique DRAM
within the memory subsystem. A unique set, bank, and
syndrome are stored in footprint to construct a unique ID for
the DRAM.
Rather than logging an error for each occurrence of a single
symbol correctable ECC memory error, the VMS error
handler maintains the CRD buffer; it creates a memory CRD
entry for new footprints and updates an existing memory
CRD entry for errors that occur within the range specified
by the ID in FOOTPRINT. This reduces the amount of data
logged overall without losing important information—errors
are logged per unique failure mode rather than on a per error
basis.
Each memory CRD entry consists of a FOOTPRINT,
STATUS, CRD CNT, PAGE MAPOUT CNT, FIRST EVENT,
LAST EVENT, LOWEST ADDRESS, and HIGHEST
ADDRESS.
FIRST EVENT, LAST EVENT, LOWEST ADDRESS and
HIGHEST ADDRESS are updated to show the range of time
and addresses of errors which have occurred for a DRAM.
CRD CNT is the total count per footprint. PAGE MAPOUT
CNT is the number of pages that have been marked bad for a
particular DRAM.
STATUS contains a record of the failure mode status of
a particular DRAM over time. This in turn determines
whether the CRD buffer is logged. For the first occurrence of
an error within a particular DRAM, the memory location is
scrubbed (corrected read data is read, then written back to
the memory location) and CRD CNT is set to 1. Since most
memory single-bit errors are transient due to alpha particles,
logging of the CRD buffer is not done immediately for the
first occurrence of an error within a DRAM. The CRD buffer,
however, is logged at the time of system shutdown (operator
or crash induced), or when a more severe memory subsystem
error occurs.

Continued on next page

5–67

Product Fault Management, Continued
If the FOOTPRINT/DRAM experiences another error
(CRD CNT > 1), VMS sets HARD SINGLE ADDRESS
or MULTIPLE ADDRESSES along with SCRUBBED in
STATUS. Scrubbing is no longer performed; instead, pages
are marked bad. In this case, VMS logs the CRD buffer
immediately. The CRD Buffer is also logged immediately
if PAGE MAPOUT THRESHOLD EXCEEDED is set in
SYSTAT as a result of pages being marked bad. The
threshold is reached if more than one page per Mbyte of
system memory is marked bad.
NOTE
CURRENT ENTRY is zero in the Memory SBE
Reduction subpacket header if the CRD buffer
was logged, not as a result of a HARD SINGLE
ADDRESS or MULTIPLE ADDRESSES error in
STATUS, but as a result of a memory uncorrectable
ECC error shown as RELATED ERROR, or as
a result of CRD BUFFER FULL or SYSTEM
SHUTDOWN, all of which are shown under
LOGGING REASON.

VMS Event
Record
Translation

The kernel error log entries are translated from binary to ASCII
using the ANALYZE/ERROR command. To invoke the error log
utility, enter the DCL command ANALYZE/ERROR_LOG.
Syntax:
ANALYZE_ERROR_LOG [/qualifier(s)] [file-spec] [,...]

Example:
$ ANALYZE/ERROR_LOG/INCLUDE=(CPU,MEMORY)/SINCE=TODAY

The error log utility translates the entry into the traditional threecolumn format. The first column shows the register mnemonics,
the second column depicts the data in hex, and the last column
shows the actual English translations.

Continued on next page

5–68

Product Fault Management, Continued
As in this example, the VMS error handler also provides support
for the /INCLUDE qualifier, such that CPU and MEMORY error
entries can be selectively translated.
Since most kernel errors are bounded to either the processor
module/system board or memory modules, the individual error
flags and fields are not covered by the service theory. Although
these flags are generally not required to diagnose a system to the
FRU, this information can be useful for component isolation.
ERF bit-to-text translation highlights all error flags that are
set, and other significant state—these are displayed in capital
letters in the third column. Otherwise, nothing is shown in the
translation column. The translation rules also have qualifiers
such that if the setting of an error flag causes other registers to be
latched, the other registers are translated as well. For example,
if a memory ECC error occurs, the syndrome and error address
fields are latched as well. If such a field is valid, the translation
is shown (for example, MEMORY ERROR ADDRESS); otherwise,
no translation is provided.

NCA_CESR register bit <09>, CP2 IO error, is equal to zero

The example on the next page shows an abbreviated error log
with numbers to highlight the key registers.
The FLAGS register is located in the packet header, which
immediately follows the system identification header; the CESR
and DSER registers are listed under the KA49 register subpacket.
CPU errors increment a VMS global counter, which can be viewed
using the DCL command SHOW ERROR.
To determine if any resources have been disabled, for example,
if cache has been disabled for the duration of the VMS session,
examine the flags for the SYSTAT register in the packet header.
In this next example, a translation buffer data parity error
latched in the TBSTS register caused a machine check exception
error.

NOTE
The memory fault interpretation procedures work only
if the memory modules have been properly installed
and configured. For example, memory modules should
be installed in slots 0A, 0B, 0C, 0D or 1E, 1F, 1G, 1H if
only one set of memory SIM modules are used, then
in the unused slots if a second set of SIM modules are
used. Also, if one set is made up of 4-MB SIM modules,
and the other set is made up of 16-MB SIM modules,
the front 16-MB SIM modules must be installed in SIM
module connectors 0A, 0B, 0C, 0D.

NOTE
Although the VMS error handler has built-in features
to aid services in memory repair, good judgment is
needed by the Service Engineer. It is essential to
understand that in many, if not most cases, correctable
ECC errors are transient in nature. No amount of repair
will fix them, as generally there is nothing to be fixed.

Uncorrectable
ECC Errors

For uncorrectable ECC errors, a memory subpacket is logged as
indicated by memory subpacket listed in the third column of the
FLAGS software register ( ). Also, the hardware register MESR
<11> ( ) of the processor register subpacket is set equal to 1, and

MEAR latches the error address ( ).

Examine the MEMCON software register ( ) under the memory
subpacket. The MEMCON register provides memory configuration

information and a MEMORY ERROR STATUS buffer ( ) that
points to the memory module(s) that is the most likely FRU.
Replace the indicated memory module.
The VMS error handler marks each page bad and attempts page

replacement, indicated in SYSTAT ( ). The DCL command
SHOW MEMORY also indicates the result of VMS page
replacement.
Uncorrectable memory errors increment the VMS global counter,
which can be viewed using the DCL command SHOW ERROR.
NOTE
If register MESR <11> was set equal to 1, but MESR
<19:12> syndrome equals 07, no memory subpacket
will be logged as a result of incorrect check bits
written to memory because of an NDAL bus parity error
detected by the NMC. In short, this indicates a problem
with the CPU module, not memory. There should be a
previous entry with MESR <22>, NDAL data parity error
set equal to 1.

Correctable
ECC Errors

For correctable ECC errors, a single-bit error (SBE) memory
subpacket is logged as indicated by memory SBE reduction
subpacket listed in the third column of the FLAGS software
register.
The memory SBE reduction subpacket header contains a
CURRENT ENTRY register that displays the number of the
Memory CRD Entry that caused the error notification. If
CURRENT ENTRY > 0, examine which bits are set in the
STATUS register for this entry. GENERATE REPORT should
be set.
NOTE
If CURRENT ENTRY = 0, then the entry was logged for
something other than a single-bit memory correctable
error Footprint. You need to examine all of the memory
CRD entries and footprints to determine the likely FRU.

Continued on next page

5–76

Product Fault Management, Continued
Look for the following:
SCRUBBED
If SCRUBBED is the only bit set in the STATUS register,
memory modules should not generally be replaced.
The kernel performs memory scrubbing of DRAM memory
cells that may flip due to transient alpha particles. Scrubbing
reads the corrected data and writes it back to the memory
location.
HARD SINGLE ADDRESS
If the second occurrence of an error within a footprint is
at the same address (LOWEST ADDRESS = HIGHEST
ADDRESS then HARD SINGLE ADDRESS is set in STATUS
along with SCRUBBED. Scrubbing is not tried after the first
occurrence of any error within a particular footprint. The
page is marked bad by VMS.
Unlike uncorrectable ECC errors, the error handling code
cannot indicate if the page has been replaced. To make a
determination, use the DCL command SHOW MEMORY. If
the page mapout threshold has not been reached ("PAGE
MAPOUT THRESHOLD EXCEEDED" is not set in SYSTAT
packet header register), the system should be restarted
at a convenient time to allow the power-up self-test and
ROM-based diagnostics to map out these pages. This can
be done by entering TEST 0 at the console prompt, running
an extended script TEST A9, or by powering down then
powering up the system. In all cases, the diagnostic code
marks the page bad for hard single address errors, as well as
any uncorrectable ECC error by default.
If there are many locations affected by hard single-cell errors,
on the order of one or more pages for each megabyte of
system memory, the memory module should be replaced.
Use the console command SHOW MEMORY to indicate the
number of bad pages for each module. For example, if the
system contains 64 MB of main memory and there are 64 or
more bad pages, the affected memory should be replaced.
Continued on next page

5–77

Product Fault Management, Continued
NOTE
Under VMS, the page mapout threshold is
calculated automatically. If "PAGE MAPOUT
THRESHOLD EXCEEDED" is set in SYSTAT, the
failing memory module should be replaced.
In cases of a new memory module used for repair or as
part of system installation, you can elect to replace the
module rather than have diagnostics map them out, even if
the threshold has not been reached for hard single-address
errors.
MULTIPLE ADDRESSES
If the second occurrence of an error within a footprint is
at a different address (LOWEST ADDRESS not equal to
HIGHEST ADDRESS), MULTIPLE ADDRESSES are set in
STATUS along with SCRUBBED. Scrubbing is attempted
for this situation. In most cases, the failing memory module
should be replaced regardless of the page mapout threshold.
If CRD BUFFER FULL is set in LOGGING REASON (located
in the subpacket header) or PAGE MAPOUT THRESHOLD
EXCEEDED is set in SYSTAT, the failing memory module should
be replaced regardless of any thresholds.
For all cases (except when SCRUBBED is the only flag set
in STATUS), isolate the offending memory by examining the
translation in FOOTPRINT called MEMORY ERROR STATUS:
The memory module is identified by its backplane position.
The memory SBE reduction subpacket header translates
the MEMCON register for memory subsystem configuration
information.
Unlike uncorrectable memory and CPU errors, the VMS global
counter, as shown by the DCL command SHOW ERROR, is not
incremented for correctable ECC errors unless it results in an
error log entry for reasons other than system shutdown.

Continued on next page

5–78

Product Fault Management, Continued
NOTE
If footprints are being generated for more than one
memory module, especially if they all have the same
bit in error, the processor module, backplane, or other
component could be the cause.
NOTE
An uncorrectable ECC error due to a ‘‘disown write’’,
results in a CRD entry similar to those for correctable
ECC errors. The FOOTPRINT longword for this entry
contains the message ‘‘Uncorrectable ECC errors
due to disown write’’. The failing module should be
replaced for this error.

Some kernel errors may result in two or more entries being
logged. If the SHAC DSSI adapters or the SGEC Ethernet
controller or other CDAL device (residing on the processor
module) encounter host main memory uncorrectable ECC errors,
main memory NXMs or CDAL parity errors or timeouts, more
than one entry results. Usually there is one polled error entry

logged by the host, and one or more device attention and other
assorted entries logged by the device drivers.
In these cases the processor module or one of the four memory
modules are the most likely cause of the errors. Therefore, it
is essential to analyze polled error entries, since a polled entry
usually represents the source of the error versus other entries,
which are aftereffects of the original error. This example provides
an abbreviated error log for a polled error.

User Environmental Test Package

Overview

When the user environmental test package (UETP) encounters
an error, it reacts like a user program. It either returns an error
message and continues, or it reports a fatal error and terminates
the image or phase. In either case, UETP assumes the hardware
is operating properly and it does not attempt to diagnose the
error.
If the cause of an error is not readily apparent, use the following
methods to diagnose the error:
VMS Error Log Utility
Run the error log utility to obtain a detailed report of
hardware and system errors. Error log reports provide
information about the state of the hardware device and I/O
request at the time of each error.
Diagnostic facilities
Use the diagnostic facilities to test exhaustively a device or
medium to isolate the source of the error.

Interpreting
UETP Output

You can monitor the progress of UETP tests at the terminal from
which they were started. This terminal always displays status
information, such as messages that announce the beginning and
end of each phase and messages that signal an error.
The tests send other types of output to various log files, depending
on how you started the tests. The log files contain output
generated by the test procedures. Even if UETP completes
successfully, with no errors displayed at the terminal, it is good
practice to check these log files for errors. Furthermore, when
errors are displayed at the terminal, check the log files for more
information about their origin and nature.

Continued on next page

5–88

User Environmental Test Package, Continued
UETP Log Files

UETP stores all information generated by all UETP tests and
phases from its current run in one or more UETP.LOG files, and
it stores the information from the previous run in one or more
OLDUETP.LOG files. If a run of UETP involves multiple passes,
there is one UETP.LOG or one OLDUETP.LOG file for each pass.
At the beginning of a run, UETP deletes all OLDUETP.LOG files,
and renames any UETP.LOG files to OLDUETP.LOG. Then UETP
creates a new UETP.LOG file and stores the information from the
current pass in the new file. Subsequent passes of UETP create
higher versions of UETP.LOG. Thus, at the end of a run of UETP
that involves multiple passes, there is one UETP.LOG file for
each pass. In producing the files UETP.LOG and OLDUETP.LOG,
UETP provides the output from the two most recent runs.
If the run involves multiple passes, UETP.LOG contains
information from all the passes. However, only information from
the latest run is stored in this file. Information from the previous
run is stored in a file named OLDUETP.LOG. Using these two
files, UETP provides the output from its tests and phases from
the two most recent runs.
The cluster test creates a NETSERVER.LOG file in SYS$TEST
for each pass on each system included in the run. If the test is
unable to report errors (for example, if the connection to another
node is lost), the NETSERVER.LOG file on that node contains
the result of the test run on that node. UETP does not purge or
delete NETSERVER.LOG files; therefore, you must delete them
occasionally to recover disk space.
If a UETP run does not complete normally, SYS$TEST might
contain other log files. Ordinarily these log files are concatenated
and placed within UETP.LOG. You can use any log files that
appear on the system disk for error checking, but you must delete
these log files before you run any new tests. You may delete these
log files yourself or rerun the entire UETP, which checks for old
UETP.LOG files and deletes them.

FEPROM Firmware Update

Overview

KA49 firmware is located on four chips, each 128 KB by 8 bits of
FLASH programmable EPROMs, for a total of 512 KB of ROM. (A
FLASH EPROM [FEPROM] is a programmable read-only memory
that uses electrical [bulk] erasure rather than ultraviolet erasure.)
FEPROMs provide nonvolatile storage of the CPU power-up
diagnostics, console interface, and operating system primary
bootstrap (VMB). An advantage of this technology is that the
entire image in the FEPROMs may be erased, reprogrammed, and
verified in place without removing the CPU module or replacing
components.
A slight disadvantage to the FEPROM technology is that the
entire part must be erased before reprogramming. Hence,
there is a small "window of vulnerability" when the CPU has
inoperable firmware. Normally, this window is less than 30
seconds. Nonetheless, an update should be allowed to execute
undisturbed.

Firmware
Update Utility

Firmware updates are provided through a package called the
firmware update utility. A firmware update utility contains a
bootable image, which can be booted from tape or Ethernet, that
performs the FEPROM update.
NOTE
The NVAX CPU chip has an area called the patchable
control store (PCS), which can be used to update the
microcode for the CPU chip.
Updates to the PCS require a new version of the
firmware. The utility may be run from either the
alternate console or the graphics console. The output
text will vary depending on the console used.

Continued on next page

5–91

FEPROM Firmware Update, Continued
A firmware update utility image consists of two parts: the update
program and the new firmware, as shown in Figure 5–16. The
update program uniformly programs, erases, reprograms, and
verifies the entire FEPROM.

Once the update has completed successfully, normal operation of
the system may continue. The operator may then either halt or
reset the system and reboot the operating system.

Updating
Firmware by
Ethernet

To update firmware across the Ethernet, the ‘‘client’’ system (the
target system to be updated) and the ‘‘server’’ system (the system
that serves boot requests) must be on the same Ethernet segment.
The maintenance operation protocol (MOP) is the transport used
to copy the network image.
Use the following procedure to update firmware across the
Ethernet:
Step

Enable the server
system’s NCP circuit.

<circuit> is the system Ethernet
circuit. Use the SHOW KNOWN

Precautions

Removing and
Installing FRUs

Only qualified service personnel should remove or install FRUs.
NOTE
It is the customer’s responsibility to back up the
software before Digital Services personnel arrive at the
site. This is important to ensure that data is not lost
during the service process. The customer should also
shut down the workstation software. Before performing
any maintenance work, Digital Services personnel must
confirm that the customer has completed both of these
tasks.
CAUTION
Electrostatic discharge (ESD) can damage integrated
circuits. Always use a grounded wrist strap (part
number 29-11762-00) and work surface-to-earth ground
when working with the internal parts of the workstation.

System FRU Removal

Before Starting

Perform these preliminary steps before removing and replacing a
FRU.
Step

Action

Verify that the symptom is not caused by improper
configuration or a loose cable.

Confirm with the customer that data has been backed
up. If not, the data could be lost (when a hard disk is at
fault).

Ensure that the operating system is shut down before
turning off the system or halting the CPU.

Enter the SHOW CONFIG command and write down the
following information:
—

System ROM version

—

Graphics type

—

Memory configuration
Verify that the configuration agrees with the
amount and type of memory modules present. If
the configuration does not agree, verify that the
memory modules are installed correctly.

—

SCSI devices and IDs
Verify that the configuration agrees with the actual
hardware. If the configuration does not agree, ensure
that the following are true:
SCSI IDs are all unique.
Cables are correctly installed.
The expansion box power is turned on first.

Wait three minutes after turning off a monitor before you
move or service it.

Error Messages

Overview

The system reports two kinds of self-test errors.
Errors that display on the console immediately after running
the self test
These error messages consist of one or two question marks to
indicate a nonfatal or fatal error, the failing FRU, the device
that failed, and a general error code.
Extended test errors
These error messages display more detailed information. To
view an extended error message, enter the SHOW ERROR
command at the console prompt, after the test has reported
an error.
Immediate Error Message Format
The following example shows the format for immediate error
messages:
?? 150 10 SCSI 0050

Message

Meaning

Indicates whether the failure is fatal or non-fatal.

150

—

A double question mark (??) indicates a fatal
error.

—

A single question mark (?) indicates a nonfatal error.

The field replaceable unit (FRU). See Table A–1.
In this case it is a SCSI drive with the device ID
set to 5.

The device identification (decimal). This value
corresponds to the left bank of four LEDs
(hexadecimal). This ID also corresponds to the
mnemonic in the next field. Use Table 5–4 to
correlate the error code to a device.

SCSI

The mnemonic of the device ID.

The error code that displays following the test
is in decimal. The extended message error codes
have a hexadecimal format. When you look up an
error code in the error code tables, you must know
whether the code is in hexadecimal or decimal.

You can display the extended error messages by entering the
SHOW ERROR command at the console prompt following the
completion of a test. The extended error message has two lines.
An error line similar to the immediate error code. The error
code (last field of the first line) is in hexadecimal.
A second line with up to eight longwords of error information.
Extended Error Message Format
The extended error messages appear in the following format:
?? 150 10 SCSI 0032
150 000E 00000005 001D001D 03200000 00000024

The audio self-test (AUD) is divided into three major sections.
Register tests
Audio tests
Interrupt tests
Registers are tested by writing data then reading back the data,
or reading the READ_ONLY registers.
The audio test generates a sequence of eight tones and sends
them to the speaker. It also performs an internal digital loopback
through the MAP. This tests the three MUX channels and
corresponds to the three AUD$MAP_DIGITAL_LOOPBACK
errors.
The interrupt test generates interrupts by loading 8 bytes into
the D-channel transmit buffer and reading them back through the
receiver buffer (eight interrupts are generated).

Use these tests with the T TC0 CAT [SCRIPTNAM] and T
TC0 SCRIPT [SCRIPTNAM] commands.

NOTE
After entering T TC0 LS, it is not always safe to run
tests which do not appear in any script. Refer to the
TURBOchannel Option User’s Guide before you run
any tests individually.

Script Contents

The following is the syntax to use to display the contents of a
script.
Syntax:
T TC0 CAT [SCRIPTNAM]

Example:
>> T TC0 CAT PST-M
*emul: t tc0 cat pst-m

DEFINITION
${#} is script language for "substitute the slot number
here." When the emulator executes each test in a
script, it automatically substitutes the slot number
for ${#}. The slot number is always zero (0) for the
VAXstation 4000 Model 60.

Self-Test Error Messages, Continued
The option test results are option dependent. TURBOchannel
options can display the tests differently. Some options show only
the <tstnam> strings. Also, some options do not have a HELP
feature, therefor the T TC0 /? command does not display (it could
even cause an error to be reported by some options).
NOTE
Read the specific TURBOchannel Option User’s Guide
to properly test the option.

Running an
Option Test

Enter the following to run an option test.
Syntax:
T TC0 / [TSTNAM]

Example:
>> T TC0/SRAM
>>

The DEFZA STATIC RAM is now tested. The SRAM option is
listed in the TURBOchannel option test display.
NOTE
If some devices have qualifiers to a particular subtest,
you can add these onto the end of the command line
as outlined in the option’s firmware specification or
user’s guide.

Executing a
Script

Enter the following to execute a script.
Syntax:
T TC0 SCRIPT [SCRIPTNAM]

The emulator shows each test within the script as it is executed.
Also, error status is checked after each test completes and is
saved for the end of the script.
NOTE
Standard scripts pst-q, pst-t, and pst-m can be run as
single tests. SCRIPT can be omitted on the command
line for these scripts. The presence of standard scripts
is optional.

the object ROM.
Syntax:
T TC0 INIT

Example:

Self-Test Error Messages, Continued
The initialization object is optional, therefore a TURBOchannel
option may or may not have an initialization function. No error
occurs if an option does not have an initialization object.

MIPS/REX
Emulator
Errors

The emulator’s function is to execute the tests. While an error
status code is maintained during testing, the emulator does not
diagnose TURBOchannel hardware failures. Error messages
should be printed by the option, using the format:
?TFL: #/test [message]

Emulator Error
Messages

Presently, there are only three MIPS/REX Emulator error
messages. Each message, a description, and recommended
corrective action follow.
Message
ERR-MIPS - DID NOT FIND ROM IN SLOT nn

Description
Emulator cannot read the ROM header in slot nn.

Continued on next page

Self-Test Error Messages, Continued
Corrective Action
Check the option seating, and the option connector and option
ROM for bent pins.
Message
ERR-MIPS - ROM OBJECT REPORTED A SEVERE ERROR

Description
The emulator received a severe error status code back from a
TURBOchannel object.
Corrective Action
Check whether a ?TFL error message displayed before this
message. Refer to the option user’s guide.
Message
ERR-MIPS - BAD ADDRESS DETECTED (ADDR address), CODE = mm

Description
Indicates that the TURBOchannel ROM code has gone outside
the expected range of addresses permitted by the TURBOchannel
firmware specification.
Corrective Action
Check whether the module is supported or is running a test not
supported by the emulator.

Diagnostic LED Codes

Overview

The system uses the eight LEDs on the control panel to indicate
the currently executing test. When power is turned on, all the
LEDs come on (LED code is FF(h)), and then display different
codes as the devices are tested.
The LED codes are divided into two fields.
The left-most four LEDs represent the device number.
The right-most four LEDs represent a substate that the
device test is currently in. LED codes E0h - FFh are reserved
for the console.

Translating
Error Codes

The eight LEDs on the lights and switches board can be
translated into two hexadecimal or binary digits in the form:
X X X X

Y Y Y Y

X X X X is the device number (binary) currently under test.
Use Table 5–4 to match the code from the LEDs to a device.
Y Y Y Y is the subtest at which the diagnostic hung.
The LEDs can be used for troubleshooting when the console device
is inoperable.

The tables in this appendix contain information to help you
diagnose problems. The tables list the symptoms, possible causes,
and suggest corrective action, as follows:
Table C–1, System Problems
Table C–2, Monitor Problems

Troubleshooting

Overview

Troubleshooting is the process of isolating and diagnosing
problems with the system. When the system does not operate
as described in the VAXstation 4000 Model 90 Owner’s Guide (EKPVAX2-OM), use the information in this section to help diagnose
the problem.
If the power-up tests complete, you can use the console error
messages to identify the failed FRU, or you can run the selftest, system test, and utility tests in Digital Services mode to
help isolate the failing FRU. The console error messages are
interpreted in Appendix A.
Use the diagnostic LEDs (listed in Appendix B) on the front of the
system to help diagnose problems when the system is unable to
set up the console.
The troubleshooting techniques described in Table C–1 do
not identify all possible problems with the system, nor do the
suggested corrective actions remedy all problems.

Precautions

Overview

Only qualified service personnel should remove or install FRUs.
Electrostatic discharge (ESD) can damage integrated circuits.
Always use a grounded wrist strap (part number 29-11762-00)
and grounded work surface when working with the internal parts
of the workstation.
NOTE
It is the customer’s responsibility to back up the
software before Digital Services personnel arrive at the
site. This is important to ensure that data is not lost
during the service process. The customer should also
shut down the workstation software. Before performing
any maintenance work, Digital Services personnel must
confirm that the customer has completed both of these
tasks.
Refer to Figure 6–1 for the location of the system FRUs.
