Bit

Function

Conversational boot. The secondary bootstrap program, SYSBOOT, prompts you
for system parameters at the console terminal.

Debug. If this flag bit is set, the operating system maps the code for the
XDELTA debugger into the system page tables of the running operating system.

Initial breakpoint. If this flag bit is set, VMS executes a breakpoint (BPT) instruction early in the bootstrapping process.

Secondary boot from boot block.
The secondary boot is a single 512byte block whose logical block number is specified in General Purpose Register R4.

Boots the VAX Diagnostic Supervisor. The secondary loader is an image called DIAGBOOT.EXE.

Boot breakpoint. This stops the primary and secondary loaders with a breakpoint (BPT) instruction before testing memory.

Image header.
The transfer address of the secondary loader image comes from the image header for that file. If this flag is not set, control shifts to the first byte of the secondary loader.

File name. VMB prompts for the name of a secondary loader.

Halt before transfer. VMB executes a HALT instruction before transferring control to the secondary loader.

No effect, since console program tests memory.

Reserved for VAX Diagnostic Supervisor.

Do not discard CRD pages.

The first line in Example 2–1 shows that the CPU in slot 1 passed
all testing. If the final # sign is missing, the last number shown is the
number of the failing test. This line of numbers is displayed only by the
processor in node 1 — and only when this processor undergoes power-up
or a system reset. This processor is not always the boot processor.

The NODE # line lists the node numbers on the XMI bus. The nodes
on this line are numbered in hexadecimal and reflect the position of the
XMI slots as you view the XMI from the front of the cabinet through
the clear card cage door.

Self-Test 2–1

The TYP line in the printout indicates the type of module at each node:
A = I/O adapter
P = scalar processor
V = vector processor
M = memory module

The STF line shows the results of self-test. This information is taken
from the self-test fail bit in the XBER register of each module. The
entries are:
+ (pass)
– (fail)
o (does not apply)

The BPD line indicates boot processor designation.
The results on the BPD line indicate:
B = Boot processor
E = Processors eligible to become boot processor
D = Processors ineligible to become boot processor
This BPD line is printed twice. After the first determination of the
boot processor, the processors go through an extended test. Since
it is possible for a processor to pass self-test (at line STF) and fail
the extended test (at ETF), the processors again determine the boot
processor following the extended test.

During the extended test (ETF) all processors run additional CPU tests
involving memory. Results printed at this ETF line indicate:
•

Two processors passed the extended test (+)

•

Two processors failed the extended test (–)

This ILV line contains a memory interleave value (ILV) for each
memory. If you have more than one interleave set, each set is indicated
by a different letter.

The line after the ILV line displays the size of each memory module
configured in the system and gives the total Mbytes of system memory.
In Example 2–1 the total is 256 Mbytes.

Console and RBD information indicates the version of read-only
memory that is installed on the processors in this system. Each
processor has a console ROM and an RBD ROM; each ROM has its
own version. In Example 2–1 all processors have version V1.00 ROM
resident. All processors should run with the same level of ROM. If your
processors have mixed levels of ROM, the ROM level of the primary

2–2 VAX 6000 Model 500 Mini-Reference

processor is displayed here, and you receive an error message that your
processors have different ROM levels.
10

The EEPROM information gives the boot processor’s version of
EEPROM and the patch level. In Example 2–1 the first number,
1.00, gives the version of the contents of the EEPROM, and the second
number, 1.00, is the console patch level. If you run processors whose
EEPROMs do not match, you will receive an error message.

SN gives the system serial number. The system serial number is also
on the cabinet.

Self-Test 2–3

Example 2-2 shows a self-test display that contains an additional line when
an optional VAXBI adapter (DWMBB) is part of the system configuration.
The XBI line provides information on the node numbers and self-test status
for modules in the VAXBI card cages, which are connected to the XMI
through a DWMBB.

Because the DWMBB does not have a module-resident self-test, its
entry for the STF line will always be "o".

The test results for the DWMBB/A and the DWMBB/B modules are
indicated on the XBI line, at the far right. In this example, the DWMBB
modules have passed self-test (XBI E +). The results of the VAXBI I/O
adapter self-tests are shown in columns 1 through F, which stand for
the VAXBI node numbers; in this configuration, node numbers 1, 2, 3,

Address Space
The design of the hardware for the system bus (the XMI) and for the
optional VAXBI bus affects addressing. The XMI card cage has its 14
slots permanently assigned to specific address locations. For the Model
500, no modules that require I/O cables can be installed in the middle
four slots (slots 6 through 9). The VAXBI bus consists of two VAXBI card
cages that are physically fastened together and logically connected as one
12-slot VAXBI bus. For more information on VAXBI node addressing, see
Section 3.2.

Register addresses for a particular device in a system are found by adding
an offset to the base address for that particular device. To distinguish
between addresses in XMI address space and addresses in VAXBI address
space, we use the following convention:
lowercase bb + offset indicates an address in VAXBI address space
uppercase BB + offset indicates an address in XMI address space

3–2 VAX 6000 Model 500 Mini-Reference

XMI I/O space is divided into private space, nodespace, and ten I/O adapter

XMI Private Space
References to XMI private space are serviced by resources local to a node,
such as local device CSRs and boot ROM. The references are not broadcast
on the XMI. XMI private space is a 24-Mbyte address region located from
E000 0000 to E17F FFFF.
XMI Nodespace
The VAX 6000 platform XMI nodespace is a collection of 16 512-Kbyte
regions located from E180 0000 to E1FF FFFF. Nodes 0 and F are not
implemented. Each XMI node is allocated one of the 512-Kbyte regions
for its control and status registers. The starting address of the 512-Kbyte
region associated with a given node is computed as follows:
E180 0000 + (Node ID x 80000)

3.1 How to Find a Register in XMI Address Space
Because XMI addresses correspond to slot and node numbers, you want to
determine the slot of the XMI card cage in which the module resides. The
slot number can be determined in two ways:
•

By looking at the XMI card cage (numbering of slots is shown in
Figure 3–1)

•

By entering at the console a SHOW CONFIGURATION command

A typical response is shown below.

Assume that you want to examine the Bus Error Register (XBER) of the
DEMNA module in slot 11, which is XMI node B. From Table 3–1, XMI
Nodespace Addresses, you can see that the nodespace base address for the
XMI module at node B is E1D8 0000. From Table 6–2, XMI Required
Registers, you can see that the XBER offset is BB + 04, so you add 04 to
the base address to get the address for that module’s XBER register. You
could examine the XBER register with the command:
>>>

Address Space 3–5

3.2 How to Find a Register in VAXBI Address Space
The first part of a VAXBI adapter’s physical XMI address depends on which
XMI slot the DWMBB/A module occupies. The second part of the address
depends on the adapter’s VAXBI node number, which is shown in the SHOW
CONFIGURATION display.
NOTE: VAXBI slot and node numbers are not identical. The placement of
the VAXBI node ID plug on the backplane determines the node ID, so seeing
that a particular option is in a certain slot does not guarantee that the slot
and node number are identical. Use the VAXBI node identification from the
SHOW CONFIGURATION command.
The XMI slot number can be determined in two ways:
•

By looking at the XMI card cage (numbering of slots is shown in
Figure 3–1)

•

By entering at the console a SHOW CONFIGURATION command

Assume that you want to examine the Device Register (DTYPE) for the
DMB32, which is node 4 in the VAXBI channel shown above (XBI E).
To get the address for the DMB32 Device Register (DTYPE), do the
following:
1. From Table 3–1, XMI Nodespace Addresses, find XMI node E and take
the first two digits for that node’s window space (FC).

3–6 VAX 6000 Model 500 Mini-Reference

2. From Table 3–2 find VAXBI node 4 and in column 2 you can see that
the starting address for VAXBI node 4 is xx00 8000.
3. Combine this second number with the two digits. You now have the
adapter’s base address (FC00 8000) in VAXBI address space, indicated
by lowercase bb.
4. From Table 3–3, VAXBI Registers, you can see that the VAXBI Device
Register (DTYPE) is at bb + 00, which is FC00 8000.
The Device Register for the DMB32 would be examined by:

2 Key to Classes:

1 = Implemented by the KA65A CPU module as specified in the VAX Architecture Reference Manual.
2 = Implemented uniquely by the KA65A CPU module.
3 = Not implemented. Read as zero; NOP on write. These registers should not be referenced during normal operation as no other instructions can be executed by the CPU until a timeout period that might be longer than device or CPU timeouts has expired.
4 = Access not allowed; accesses result in a reserved operand fault.
5 = Accessible, but not fully implemented; accesses yield UNPREDICTABLE results.
6 = Implemented by the FV64 vector module.
n Init = The register is initialized on a KA65A CPU module reset (power-up, system reset, and node reset).

4.4 Machine Checks
A machine check exception is reported through SCB vector 04 (hex) when an
error condition is detected. The frame pushed on the stack for a machine
check indicates the type of error and provides internal state information
that helps to identify the cause of the error. The machine check stack frame
is shown in Figure 4–64 and its parameters are described in Table 4–5.
Table 4–6 lists and describes the machine check codes.
Software must acknowledge machine checks by writing a zero to IPR38,
MCESR, as a second machine check causes an ERR_MCHK_MCHK console
halt.

Description

Parameter Byte Count

The size of the stack frame in bytes, not including PSL, PC, and the
byte count longword. It is always 18 (hex) bytes. Stack frame PC
and PSL values are always referenced using this count as an offset from the stack pointer.

R (VAX Restart bit)

A flag from the hardware and microcode to the operating system to be used in the software equation to determine if the current macroinstruction is restartable after error cleanup. Other terms in the equation are PSL<27> (First
Part Done, FPD), PCSTS<6> (Trap2), and XBEER0<11> (Unlock Write Pending, UWP). If R=1, no state has been changed
by the instruction that was executing when the error was detected.
If R=0, state had been changed by the instruction.

Machine check code
(bits<15:0>)

Table 4–6 lists and describes the machine check codes.

The virtual address being processed by the CPU at the
time of the fault.
VA is not necessarily relevant; the error handler checks the specific error address corresponding to the device or mechanism that signaled the error.

VIBA

The CPU prefetch virtual instruction buffer address at the time of
the fault.

ICCS..SISR

The interrupt state information where bit<22> is ICCS<6> and
bits<15:1> are SISR<15:1>.

Internal State

The internal state at the time of the fault.
nal state has the following layout:
Delta-PC, bits<31:24>

The inter-

Difference between the values of the
current incremented PC at the time
that the machine check was detected and the PC of the instruction opcode. The exact interpretation
of Delta-PC requires a detailed knowledge of the internal pipeline operation of the MP-chip and is not used
by software to make recovery decisions.

DWMBB Adapter Registers
The DWMBB adapter consists of two modules: an XMI module in the XMI
card cage and a VAXBI module in the VAXBI card cage. Table 6–1 lists
the DWMBB registers: some of which are XMI required registers, some
DWMBB/A registers, some DWMBB/B registers, and the VAXBI Device
Register for the DWMBB/B module.
Register addresses for a particular device in a system are found by adding
an offset to the base address for that device. To distinguish between
addresses in VAXBI address space and addresses in XMI address space,
we use the following convention:
lowercase bb + offset indicates an address in VAXBI address space
uppercase BB + offset indicates an address in XMI address space

1 The first letter of the mnemonic indicates the following:

X=XMI register, resides on the DWMBB/A module
A=Resides on the DWMBB/A module
B=Resides on the DWMBB/B module; accessible from the XMI bus
2 The abbreviation "BB" refers to the base address of an XMI node (the address of the first loca-

tion of the nodespace). The abbreviation "bb" refers to the base address in VAXBI nodespace.

3 This is a VAXBI register.

Chapter 7

Vector Module Registers
The vector module registers consist of the following:
•

Internal processor registers (IPRs) (see Table 7–1)

•

Vector indirect registers (see Table 7–2)

•

Vector Length, Vector Count, and Vector Mask control registers

This chapter explains how to access the registers and then shows the
registers. See your System Technical User’s Guide for complete descriptions
of the registers.

7.1 Console Commands to Access Registers
From the console, the EXAMINE and DEPOSIT commands are used to
read and write the IPRs and the vector indirect registers. The vector data
registers can also be accessed from the console. The qualifiers differ:
•

/I — to read and write the IPRs

•

/M — to read and write the vector indirect registers, except for the 16
vector data registers

•

/VE — to read and write the vector data registers

From the console, the Vector Length, Vector Count, and Vector Mask control
registers can be specified as VLR, VCR, and VMR after DEPOSIT and
EXAMINE commands with no qualifiers. VLR and VCR are 7-bit registers
(Figure 7–1), and VMR is a 64-bit register (Figure 7–2).

Addresses from 400–45F in this column specify the address of Verse chip 0; addresses for Verse chips 1, 2, and 3 are found by adding 1, 2, and 3 to the address given. A read must specify each Verse chip by its own address; a write to the address given in the table (for Verse chip 0) is broadcast to all Verse chips.
