The svstem hardware consists of the processor(s) (two on the VAX 8800
one on the 8700, 8550, and 8500), memories, and 1 /0 unit(s) (two on the

VAX 8800, one on the 8700, 8550 and 8500), connected by a common

set of backplane wires. /0 consists of the Bl (Backplane Interconnect)
which allows for NI (Network Interconnect), and Cl (Cluster Interconnect)
apabill:tie‘s These bus architectures, coupled with a 70MB/sec CPU

/Memory band width and four [ /O channels, provide high 1,0 flexibility

and pertormance. An Environmental Monitoring Module (EMM) monitors
voltage, temperature, and air flow, protecting the CPU. A single console

svstemn controls the prmessw(\) Figures 2—-1 and

2.2

The Console System
The VAX console is a secondary computer system that allows you to
control and monitor the primary VAX systems. The console contains
a processor and memory for managing the transactions between you
(the operator) and the VAX system, a fitOT&E,(‘ device for microcode, and

additional disk space for the console, bootstrap, and diagnostic programs.
The console also has terminal interfaces to provide access to both local
and remiote terminals. A console interface links the console subsystem

and the VAX processor. The console interface consists of two parts: a
Real Time Interface (RTI), which extends the console's 1/0 capabilities,
and a section of logic on the VAX clock module dedicated to supporting
console functions. Figure 2-3 is a block diagram of the console subsystem
hardware.
On the VAX 8800, two log:cally independent consoles reside in one
physical console, allowing beth CPUs to be controlled independently.

(Some interdependencies exist, such as certain clock functions.)

You control the VAX CPU(s) at the console with the Console Command
Language, described in Chaptoer 5. These commands provide control over
the VAX CPU(s) with output to a CRT screen and an optional printer.

221 | Console Hardware
The console contains 1024 kilobytes (KB) of memory, RX50 diskettes, and
a fixed disk. The console comes with a VR201 monochrome monitor and
an LK201 keyboard. An optional printer is available.

. 2.2.1.1

Printer Interface
A printer is a console option connected to the console through a serial
printer port on the back of the console system unit. The port is capable
of performing at programmable rates up to 19.2 Kbaud and uses RS423
signal levels.

2.2.1.2

Console Storage Device
VAX microcode, console programs, and the programs that help to run or
diagnose the VAX and console systems are stored on the console’s fixed
disk. Diskettes can be used as intermediate storage between the VAX and
the console. The console has sole write access its own fixed disk, and the
VAX operating system has write access to the diskettes.

2.2.1.3 Time of Year Clock
The console has its own clock, which uses an MC146818 CMOS chip
with backup power supplied by a rechargeable NiCD battery. The console
increments the clock every second. A Valid RAM and Time (VRT) bit
indicates the status of the clock. (An asserted VRT bit indicates that the
clock has not Jost power and that the time and date have been updated
properly since the last initialization.) The VAX Time of Day Registeris
implemented in console software, using the console’s Time of Year Clock.
The VAX CPU requests Time of Year information from the console when
necessary.

2.2.1.4 Real Time Interface
The console communicates with the CPU(s) over a Real Time Interface
module (RTI), using the 24-bit Parallel Peripheral Interface bus (PPI)
connected to the VAX clock and console interface module located in the

CPU backplane. One of the two RS423 serial line interfaces on the RTl is
used to communicate with the Environmental Monitoring Module (EMM),
to enable the console to monitor and control the VAX power subsystem.
The other R5423 interface is not used.

2.2.1.5

External Port
The console system module offers a Communication Port—an asynchronous or bit- and byte-synchronous R5423 port with modem control.

This port is used to establish a diagnostic link to the system from a remote
location. A 7201 USART is employed, operating at a rate up to 19.2Kbaud
asynchronously or 740Kbaud synchronously. This port can be accessed
from the back of the console system unit. When a modem is connected
to the Communication Port, it operates like a typical VAX remote diagnostic port. Use a BC22F 25-pin connector to connect the modem to the
Communication Port.

Use a null modem cable to connect a remote terminal to the Communications.
Port of the console system unit.

2-6 System Hardware

‘

2.2.1.6

Console interface
The console interface resides on the VAX clock module and shares it with
the VAX system clock.
The console interface allows the console to communicate with and control
the VAX system and provides the VAX with access to the console subsystem components. The console interfaceis linked to the rest of the console
subsystem by a 24-bit bus from the Programmable Peripheral Interface on
the Real Time Interface (RTI).
The VAX side of the console interface contains data, address, and control

paths to the Instruction Decoder module ¢ the CPU. For the VAX 8800, a
duplicate set of connections is available to the second CPU.
The console controls the system clock. The clock can be stopped and
restarted, stepped any number of clock cycles, or stopped at preselected
program breakpoints by commands entered at the console terminal.
The console has access to the 16 channels of the VAX 8800 Visibility Bus,
which provides access to selected latches of the VAX 8800 system for

diagnostics. Each channel is a serial path from one of the 16 modules of
the left and right CPUs of the VAX 8800 or from one of the 8 modules of
the VAX 8700, 8550, and 8500.
Each VAX CPU has seven Internal Processor Registers on the console
interface. Four registers are for passing data to and from the console
processor: the Console Receive Data Buffer, Console Receive Control
and Status, Console Transmit Data Buffer, and Console Transmit Control
and Status. The remaining three registers are used in the Interval Clock to
time programmed intervals for the VAX CPU. These are the Interval Count
Register, Next Interval Count Register, and the Interval Count Control and

Status. One set of the seven IPRs on the interface exist for each CPU.
Partial contents of the System Identification Register are accessed through
the console interface. The console takes this data, along with the remainder of the system identification data stored on the console disk, and
deposits it in the Slow Data File (SDF) at boot time. As a result, the
CPU looks for System Identification Register contents only in the Slow
Data File. See the descriptions of the DEPOSIT, EXAMINE, and LOAD

commands in Chapter 5 for more information about the Slow Data File.

23 Power System
T'he VAX power system consists of a Modular Power Supply Module

(MPS), an Environmental Monitoring Module, a fan, and AC and DC
power distribution. The VAX 8800 also has a battery backup unit (BBU).

. 231 : ,Ennironment Menitoring Module
The Environmental Monitoring Module controls the VAX power system
and protects the VAX hardware from environmentally induced damage.
The EMM senses the state of the system’s environment and relays this
information to the console. If the temperature exceeds the limits or if the
air flow goes below specified limits, the console issues commands to the
EMM to turn the power off. When the situation is corrected, the EMM
will turn the power back on.
When the system’s power-up sequence is initiated, both the console

and the EMM undergo self testing, after which the console loads its
operational software. As part of the system power-up sequence, the
console must initialize each EMM’s parameter table and then instruct it
to power on the rest of the computer logic. After the power-up sequence,
the console requests the EMM to compare the environmental conditions
with the nominal values in the initialization sequence and to report any
detected discrepancies. The EMM senses the module temperature, inlet

air temperature, air flow, and DC voltage levels. Power failure signals are
generated in the EMM, and the EMM implements the parallel and serial

keying of modules to detect when a module is missing or in the incorrect
slot.
Problems that can cause the EMM to turn off the system power might

include regulator voltages out of tolerance, excessive air temperatures in
the cabinet, or heat buildup across the logic components, insufficient air
flow, and changes in the MODULE OK signals from the regulators.

Because the Modular Power Supply is controlled by the system console,

the MPS subsystem acts as an intelligent peripheral, with the EMM as the
controller.

2-8 System Hardware

Chapter 3

The VAX console software is a set of application tasks built on the console
operating systern (P/OS). This chapter describes those tasks.
The console provides control over one or two CPUs with the following
general functions:
*

Control and monitor the VAX power system through the Environmental
Monitoring Module

Load microcode

Provide a “soft” processor control panel—software that is equivalent to
processor control panel switches and lights on previous VAX systems

Initialize the CPU(s) and major buses

Provide a means to identify, boot, or restart the VAX 8700,/8500/8550
CPU

Provide a means to identify, boot, or restart the primary and secondary
CPUs on the VAX 8800

Provide console, program, and remote user modes

Control diagnostic sessions

The console subsystem is the primary interface for service activity and
in-depth troubleshooting. The console software application allows the
manipulation of registers, control stores, and memory and acts as an
operator service terminal for the VAX operating system.
The console program implements the program and console modes, log
files, EMM support, the Micromonitor, and remote access. The console

functions not implemented by the console program are the logical block
server, the file server, spawned microdiagnostics, and drivers. The console

Console System Software

3-1

program is the only way to power down and power up the VAX, and
therefore must always be running.
The console program maintains constant read requests to the EMM,
the remote port (when enabled), and the local terminal. In console
mode, the local and remote read requests are for entire lines; in program
mode, the requests are for single characters. The local and remote ports
can be in different modes or the same mode. Therefore, the console’s
terminal driver uses console mode to implement special characters, such as
CTRL/U and the DELETE key. The VAX's terminal driver uses program
mode to implement these special characters.

3.1

Legical and Physical CPUs on the VAX 8800
The two VAX 8800 CPUs are known logically as the Primary and the
Secondary CPUs. Physically, they are known as Left and Right. Console
software maps the logical CPUs, Primary and Secondary, to the physical
CPUs, Left and Right, respectively.

3.2 Scope for Commands That Affect More Than One VAX 8800 CPU
Some commands, such as EXAMINE, apply only to one of the VAX 8800
CPUs. Other commands including the initialization commands HALT,
INITIALIZE, LOAD/WCS, LOAD/CACHE, LOAD/IBD, LOAD/SDF,
SENSE REVISION CPU, START/CONTROLSTORE, TEST, VERIFY
MODULE PLACEMENT, and VERIFY REVISION CPU apply to either or
both CPUs.
A VAX 8800 CPU reponds to a command when it is both available and
selected. The CPU is available if the following conditions are true:
¢

The CPU has passed the VERIFY MODULE PLACEMENT test.

The CPU is enabled because it is the primary CPU or because the
ENABLE SECONDARY command has been issued successfully.

The CPU is working (has passed all diagnostics) and thus has not been
marked as unavailable.

A VAX 8800 CPUis “selected” by the SET CPU console command. You

can vary the scope of a command by using the SET CPU qualifiers BOTH,
LEFT, RIGHT, CURRENT_PRIMARY, NEXT_PRIMARY,
CURRENT_SECONDARY, and NEXT_SECONDARY.

3-2 Console System Scftware

‘

The CPU is marked "unavailable” if any of the following commands fail:
LOAD/WCS
LOAD/CACHE
LOAD/IBD

LOAD /SDF
VERIFY MODULE PLACEMENT

3.3

The System Clocks
Commands that require clocks to be off in order to execute check the clock
state (ON /OFF), and the state of the CPU (RUNNING/HALTED). If the
clocks are on and either CPU is running, the console issues a prompt
asking if you wish to stop the clocks before continuing. If you reply with
a "Y", the clocks are stopped and the command executes. If you reply
with anvthmg else, the command terminates without being executed. If
the CPU(s) are halted and the clocks are in the wrong state, the console
puts the clocks in the correct state and executes the command.

CAUTION
Stopping the clocks while the operating system is running (on
any CPU) can cause the operating system to crash.

3.4

Seoftware-Implemented Precessor Control Panel
Unlike previous VAX consoles, this console does not have a physical front
panel with lights and switches. The typical front panel functions have
been implemented in the console software.
Console software implements these “front panel” functions, using the
following commands. (The commands are described in Chapter 5.)

Controlling power to the VAX system:
ENABLE/DISABLE AUTO POWERON
POWER ON/OFF /STANDBY

Enabling/disabling remote port:

Cansole System Software

3-3

ENABLE/DISABLE REMOTE USER

Selecting the auto restart and boot functions:
ENABLE/DISABLE AUTO BOOT
ENABLE/DISABLE AUTO RESTART

The AUTO_POWERON, AUTO_BOOT, and AUTO_RESTART

keyswitches are disabled on new systems.

341

Seftware-implemented Keyswitches
Processor control panel keyswitches are implemented in software.
The AUTO_BOOT and AUTO_RESTART commands work together
as described in Table 3-1. These “switch settings” are checked in the
SYSINIT.COM and RESTAR.COM files to determine whether to restart
or boot the system following a power failure recovery or an error halt.
The command file checks the AUTO_RESTART “switch setting” first.
Depending on its setting or the outcome of that first operation, the

AUTO_BOOT “switch setting” may or may not be tested.

Also see Figure 4-1 for more information on the software-implemented

power is applied to the CPU following a CPU power failure recovery.

WARNING
If repair workis necessary on the CPU, vou maust issue the
POWER OFF command and shut off the main power breaker
of the CPU. The following safety feature is designed to protect
those working on the system hardware:

3-4

Comole System Softmse

When you issue the POWER OFF command, the console saves
the contents of the AUTO_POWERON “switch setting” and
disables it. Then, with any kind of power failure (including
turning off the console), the initialization procedure (SYSINIT)
detects that AUTO__POWERON is disabled and does not power
up the system. That prevents a console-only power failure, for
instance, from powering up the entire system.
When the work on the system hardware is finished, turn on
the circuit breaker and issue the POWER ON command. The
AUTO_POWERON value is restored to its original setting

{(prior to the POWER OFF command).
If you have enabled the AUTO_POWERON keyswitch and
have not issued a POWER OFF command, the console responds
to power failures automatically. If the circuit breaker is then
inadvertently turned on, the console automatically powers
up the system, endangering those working on the system
hardware.

3.5

Console Directory Organization
Files used by the console program reside in more than one directory. The
directories used are [CONSOLE] and [8800], [8700], [8550], and {8500}
(depending upon your system). The [CONSOLE] directory contains all
files that are shared by all the VAX models: 8800, 8700, 8550, and 8500.
The other directories contain the VAX processor-specific files. For example,
there may be files in the [8800] and [8500] directories with the same name
but which are actually different. To locate system files, the console first
searches in the VAX-specific directory (according to the VAX model the
console is connected to). If the desired file is not found, it searches in the
[CONSOLE] directory.
From the console user’s point of view, this organization has the following
impact:

[f you need to locate a file that the console program uses (for example,
to edit a command file) and you have an 8800, look for the file in
[8800]. If the file is not there, look in [CONSOLE]. If the file is in
neither directory, then the file is not usable by the 8800 console.

If you want to create a new console command file for an 8500, for
example, you should put it in the [8500] directory. This assures that
the 8500 console program will locate the file and also that it would not
be used if the consoleis later connected to an 8800.
Console System Software

3-8

To run the console program from DCL, type RUN CONTROL if the
default directory is [CONSOLE]. If you have changed the default
directory, you must type RUN [CONSOLE;CO\ETROL since the
CONTROL program is lccated in [CONSOLE]. The location of the
default directory does not affect the console program.

Because the search path is hard coded into the console program, you
cannot specify a directory as part of a file name used in a console

command. For example, the console command @[8800]TESTFILE is
not allowed. You must use just @TESTFILE.

2.6

One exception to the directory organization is the file CI780.BIN,
which must be in the directory {USERFILES].

Because of its size, the console log file LOGFILE.DAT is in directory
[CONSOLE] instead of in several directories. This file differs between
models. Therefore, if you connect your console to a different machine
type delete the file [CONSOLE]JLOGFILE.DAT before running the
CONTROL program. Otherwise you will get an error message.

Modes of Console Operation
The VAX has two modes of operation: console mode and program mode.

Local terminals have the same two modes: console mode and program
mode. For remote terminals these modes are called remote console mode
and remote user mode.
In console mode (local or remote), the VAX CPU can be either running
or halted and the console terminal can execute some or all console commands. In program mode (called user mode for remote terminals), the
CPU must be running and the console terminal cannot execute console
commangds.

3-8

Consale System Software

3.6.1

Conscle Mede
In console mode, you can control and monitor the VAX (running or halted)
from the console terminal. Though not all commands are available when
the VAX is still running (in console mode prior to the HALT command),
a set of console commands is available when the CPU is halted. These
commands allow you to perform privileged operations, such as depositing
to and examining locations in main memory, GPRs, and IPRs; stepping
through macrocode or microcode; controlling the system clock; and more.
You may also make a list of these console commands to be run as a

program from the console processor.
The VAX CPU assists the execution of console command functions that the
console cannot perform alone. For example, EXAMINEs and DEPOSITs

to main memory or internal registers require CPU intervention because of
the access limitations of the console. The CPU must be halted to allow
the portion of microcode that is dedicated to assisting the console to run.
The VAX CPU does not respond to interrupts while halted. In order to
communicate with the console during a halt, the CPU must poll the Ready
and Done bits of the Console Terminal Control and Status Registers. The
console processor, however, still employs interrupts in performing its side

of the communication process.

3.6.2

Program Mode
While the console can be in console mode when the VAX is running

or halted, program mode operates only while the CPU is running. In
program mode, the console terminal is like a user terminal, passing input
to software in the CPU and displaying the output. Console commands
entered at the console terminal are not recognized, as they are no longer
sent to the console processor for interpretation. One exception is CTRL/P
on the local console terminal which returns the console to console mode.
CTRL/P works on both the local and remote terminals to change from
program mode to console mode. The one exception is that if REMOTE

CONSOLE is disabled, CTRL/P on the remote port is treated like any
other program mode character.

Corsnle Systesii Software

3-7

3.7

Wiuitiple Command Streams
The local console is always enabled to some degree when the remote
termtinal is active (so that the remote terminal can be disabled). The

commands available at the local terminal depend on the state of the
remote port and whether the local terminal is enabled when the remote
connection is active. See ENABLE LOCAL CONSOLE in Chapter 5.

Commands from the local and remote ports are called the local and
remote command streams.
Another feature of the VAX 8800 is that the secondary CPU can reboot
independently of any activity in the primary CPU. A third stream of commands, called the reboot stream, can execute independently of commands
entered at either the local or remote console. The command stream is also
used to implement several miscellaneous software commands, such as
Boot This CPU and Boot Other CPU (see Section 3.10).
The console program implements the three independent command streams
by having a separate data base for each stream. The console program

alternates between the command streams on a line-by-line basis. Thus,
if any stream is executing a long command, such as LOAD/WCS, you
may notice a delaved response when executing commands on another

command stream.

3.8 Status Monitoring
Before executing each console command, the console program checks
for the changes described in the following sections. Status changes are
displayed on the local terminal and on the remote terminal, if enabled.

3.8.1

Power Change
Unexpected power changes are reported. This situation is usually created
by the EMM commanding a TOTAL OFF to the main circuit breaker.
{Note that total power offs are normally preceded by a 5-minute warning

period.)

3-8

Console System Software

3.8.2

Clock Change
If the clock has stopped due to a STOP ON MICROMATCH (see SET
SOMM command in Chapter 5), the clock change is reported.

3.8.3

Remote Port Change
If the Communication Port modem detects a carrier change, which in-

dicates that a remote console has been connected or disconnected, the
change is reported.

3.8.4

Halt Niessages
Prior to executing a new console command, the console displays pending
HALT messages.

3.9

Console Messages
The console program generates informational, warning, and error messages, which include a console “beep” and a date-and-time stamp. These
message are listed and explained in Appendix C.
Error messages can be printed while a command line is being parsed,
while a command is executing, or while status is being monitored.

3.10

Miscellaneous Operating System Commands
The operating system (or macrodiagnostic) can request different console
functions, described in the following sections.

Console System Seftware

3-8

3.10.1 Beet This CPU
If issued by the primary VAX 8800 CPU or the 8700, 8550, or 8500 CPU,

the command @DEFBOO.COM is entered into the reboot command
stream.

if issued by the secondary VAX 8800 CPU, the command @SECBOQ.COM
is entered into the reboot command stream.

3.10.2 Boot Other CPU (VAX 8800)
If issued by the primary VAX 8800 CPU or the 8700, 8550, or 8500 CPU,
the command @SECBOO.COM is entered into the reboot command
stream.

CAUTION
If the @SECBOO.COM command is issued by the VAX 8700,
8500, or 8550 CPU, the results are unpredictable.
If issued by the secondary VAX 8800 CPU, the command @DEFBOO.COM
is entered into the reboot command stream.

3.10.3

UNJAM
The UNJAM signal is asserted and deasserted.

3.10.4

Clear Warm Start Flag
The console maintains a “warm start” flag (see glossary) to prevent repeated attempts to restart a failing operating system. If the warm start flag
is not set after the operating system halts, a restart is attempted. If the
restart is successful, the warm start flagis cleared. If a restart is attempted
and the warm start flag is already set, no further attempt is made and all
processing stops.

3-10 Console System Sohiware

3105 Clear Cold Start Flag
The console maintains a “cold start” flag (see glossary) to prevent repeated
attempts to load and start (bootstrap) an operating system. If the cold
start flag is not set after a request to boot the operating system, a boot is

attempted. If the boot is successful, the the cold start flag is cleared. If
a bootstrap is attempted and the cold start flag is already set, no further
action is taken to boot.

Everything that appears on the console terminal in console mode and

OPAO: output from the VAX is saved in a log file, a circular buffer that
can store 3000 blocks of output. (On the VAX 8800, each CPU contains

a separate log file.) In console mode, input and output are logged. In

program mode, input and output are not logged (but are
in effect, because

the characters echoed by the operating system are logged). To avoid

~ logging your program mode session, use the command SET TERMINAL

OPAn: (where n = 4 for local console and n = 5 for remote console) prior

to issuing the command SET TERMINAL PROGRAM. To log program
maode activity again, use the console command SET TERMINAL OPAOD:.

The SHOW LOGFILE command provides a window, which can be moved
up and down, into the log file. See Chapter 5 for a description of SHOW
LOCFILE.

The first time you start up the system following hardware/software
installation, follow the start-up procedure described in the next section.
After the first time, start the system by pressing the “On” (1) switch on
the console’s system unit. The console executes the power-up and systeminitialization sequence (described in Section 4.4). The first image on your
screen is the DIGITAL logo, followed by the VAX {8800, 8700, 8550, or

Depending on the outcome of system initialization, the system enters
program mode or remains in console mode. If the svstem enters program
mode, the system initialization and boot/restart is successful. If the
system stays in console mode, the system initialization failed or the
AUTO_BOOT and/or AUTO_RESTART switches are disabled. The
successful completion of the START command in the boot file and restart
file constitutes successful system initialization.

4.3

Starting the System the First Time
The first time you start up the system, the system manager must install
the VAX operating system. Instructions for installing the operating system

are in the User’s Guide for your system. After the VAX operating system
has been installed, modify the boot command files to reflect your system’s
configuration. You can aiso set the software-implemented keyswitches
and EMM parameter files. The software-implemented switches (described
in Section 3.4.1) are disabled, and the system initialization procedure does
not complete the first time it powers up. Follow these steps to set up the

console to boot the VAX operating system. This procedure assumes that
the console software is installed.
1.

Turn the console off and then on to automatically execute the

SYSINIT.COM file. The first time SYSINIT.COM runs, it exits to
console mode (>> > > prompt) when it attempts to power up the
CPU(s). That happens because the AUTO_POWERON keyswitch is
disabled on new systems.
4-2

Using the Console

Once in console mode, you can enable the keyswitches AUTO_.
POWERON, AUTO_BOOT, and AUTO_RESTART with the ENABLE
command (see Chapter 5).
Now exit console mode by entering EXIT. The following message
appears:

At the console mode prompt, enter the following console commands:

@SYSINIT

The SYSINIT.COM file executes and automatically creates a memory configuration file, MEMCONFIG.DAT, if one is not found. Also, depending
on the keyswitch settings, SYSINIT.COM attempts to boot the VAX.

4.4

Powering Up and Initializing the System
When the VAX is turned on (by turning on the console), power is applied
to the power supply control logic, to the Environmental Monitoring

Module (EMM), and then to the console. Both the EMM and console
administer self-tests to verify their operations as part of their power-up
procedures. The EMM also creates an environmental parameter list in its
RAM and begins performing a limited number of monitoring tasks, using
the list to determine what conditions are considered tolerable.
Once the console and EMM systems have been verified, the console exe-

cutes SYSINIT.COM. If a system initialization is already in progress, the
console executes a POWER OFF command and (provxded the power is
on} enters console mode. (System initialization is defined as execution
of SYSINIT.COM through the successful execution of a START command.) You should then enter the following commands to restart system
initialization:
R

’%"P%Q'EP U“”

The system initialization procedure then attempts to establish communications with the EMM. When successful, a more extensive list of
environmental parameters are loaded into the EMM RAM, providing the
EMM with monitoring capabilities specific to the VAX system. If the VAX
power is off, the console attempts to turn on the VAX system power ac-

cording to the programmed sequence in the command file SYSINIT.COM.
If the AUTO_POWERON keyswitch is enabled, the power is turned on.
If the AUTO_POWERON keyswitchis disabled, SYSINIT exits.

If f SYSYSINIT exits, enter the E&EE@mfig commarnds to continue execution of
the system initialization procedures.
g

VAX modules in the CPU backplane are keyed electronically and with

the Visibility Bus (VBUS) to insure the modules are installed correctly.
Electronic keying uses the microcode and ensures the four modules (CPU,
Clock, NBIA and MCL) are in the correct slots. If they are in the wrong
slots, the EMM does not operate and the POWER ON cemmand has no
effect. VBUS keying ensures the eight CPU modules are in the correct
slots. 1f a module is in the wrong slot, in, the CPU will not operate even
with the power on.

The console also tests its interface to the CPU at power-up time. Major
data, address, and control paths on the console interface may be looped

back to the console processor. These paths can be checked by writing to
the interface and reading back the data. The console has access to hardware and software revision-level data from the Visibility Bus, backplane,

and console fixed disk. The console collects that data and determines
the compatibility of the hardware and software components during the
initialization process.
VAX firmware is loaded into the Control Store and RAMs from the
console’s fixed disk. The console loads the Control Store, Decoder RAMs,

and Cache control store. The remainder of the VAX RAMs loaded from
the console receive their data with the assistance of microcode running
in the CPU. On the VAX 8800, an unbuffered path on the interface to
each of the CPUs allows the control store of each CPU to be loaded
independently.
The microcode then begins to execute, thus starting the CPU.

Originating on the console are the UNJAM and CPU INIT initialization
signals to the Memory Interconnect (NMI) and CPU. The console controls
the assertion or deassertion of these signals during initialization and while
the maciine is running. These commands initialize the CPU to a known
state and establish a stable state on the NML
The system initialization procedure checks the AUTO_RESTART

kevswitch. If it is enabled, the system attempts to restart the VAX operating system. 1f the AUTO_RESTART switch is disabled or the restart
fails, the AUTO_BOOT keyswitch is checked. If it is enabled, a boot is
attempted. If the boot fails or the AUTO_BOOT keyswitch is disabled,
the system remains halted and in console mode. See Figure 4-1 for a
flowchart of this boot /restart procedure.

Using the Console

4-5

4.5

Recovering from a Power Failure
After a power failure, the console determines whether the console or the

CPU failed.
For a console-only power failure (the console power switch is pushed
to the “Off” position or the console is unplugged), the console program
restores the console state, which is saved in a log file. The information

includes the last known operating state of the CPU(s) (halted or running) and the console mode (console or program). The console interface
hardware registers are restored, and the console returns to its last mode.

If the console is recovering from a CPU power failure, the console forces
the execution of the SYSINIT.COM file.

4.6

Restarting After a Halt
If the operating system requests a reboot following a system halt, the

console executes DEFBOO.COM, regardiess of the keyswitch settings.
if the operating system does not request a reboot after a system halt, the

console executes RESTAR.COM, which does the following:

Checks the AUTO_RESTART keyswitch. If it is not enabled, the
console checks the AUTO_BOOT keyswitch. If it is enabled, the
primary CPU is booted (DEFBOO.COM is executed).

|f neither AUTO_RESTART nor AUTO_BOOT is enabled, the console
remains halted by exiting RESTAR.COM.

If AUTO_RESTART is enabled, the restart command procedure
(RESTAR.COM) is executed.

If a restart parameter block is located, RESTAR.COM completes.

If a restart parameter block is not located and AUTO_BOOT is en-

abled, a reboot is attempted by executing DEFBOO.COM.
¢

If the restart parameter block is not located and the AUTO_BOOT
keyswitch is disabled, RESTAR.COM exits and leaves the system
halted.

Moving Setween Console and Pregram Modes
You can use the VAX console as a console terminal in console mode or

as a user terminal interfacing with the VAX operating system in program
mode. After the system successfully initializes, the console moves into
program mode, from which it can interact with the VAX operating system.
To move the console from program mode to console mode, type CTRL/P.
To return to program mode, enter the SET TERMINAL PROGRAM
command.

After CTRL/P, you can enter the HALT command to halt the processor
and run Console Support Microcode. To move from the halted console
mode back to program mode, tvpe CONTINUE.
If you type EXIT to go from console mode to P/OS, type RUN CONTROL
to reenter console mode.

NOTE

After entering CTRL/P or SET TERMINAL PROGRAM, wait
for the console prompt or the VAX operating system prompt
> > > before typing. That is because the type-ahead capability is disabled while the processor changes modes. For instance,
if you type three commands, such as:
CTRL/P
>
»

>
>

HALT
SHOW CPU

before the console changes from program mode to console
mode, the commands do not work as expected, because the
console is not in a state to execute the last two commands.
The console ID determines if characters echoed in program

mode are logged. The default console ID is OPAQ:. All OPAO:
data is logged. To change the console ID, use the command
SET TERMINAL OPA4 for the local console, or use SET
TERMINAL OPAS for the remote console. Enter the command
prior to issuing the SET TERMINAL PROGRAM command.

Adding and Removing Memory
To add or remove memory from your VAX system, use the following
steps:

1. Create a new MEMCONFIG.DAT file with the following steps:
In console mode, enter the following commands:
> = >

POWER OFF

You are now in P/OS. Change the memory boards.

2. Enter the following command to remove old copies of the memory
configuration table:

$ DELETE MEMCONFIG.DAT;*

Run the console software, either by using the Main Menu application
CONSOLE/PRODCL or the following P/OS command:
$ RUN CONTROL

You are now in console mode.

Enter the following commands:
$ POWER ON
$ @SYSINIT

The system initialization procedure creates a new MEMCONFIG.DAT file,
using the new memory configuration.

4.9

Installing the Conscle Operating System and Applications
The console operating system (P/05) and console applications (PRO

/DCL, PRO/Communications) are installed on the console’s fixed disk

at the factory. Under most circumstances, you do not need to reinstall
the operating system or applications. However, if you need to install
any of them (for example, if you have hardware problems or if there is
a console software update), refer to Appendix E. Generally, your service
representative can determine whether to reinstall the console operating
system and/or any of the applications.

Using the Console

BOOT Command Prccedures
Your VAX system is delivered with a set of templates for boot files,
conversational boot files, and files for stopping in the primary bootstrap
program (VMB) for debug purposes. These templates are set up for and
named after the following devices:
e

BC1750

BDA50

UDA50

The following naming conventions are used for the templates:

dddBOO.COM - Boot command procedures

dddGEN.COM - Conversational boot command procedures

°*

dddXDT.COM - XDELTA boot command procedures

where: ddd = BC! or BDA or UDA

When your system is installed, these command files contain instructions to
deposit zeros in R1, R2, and R3. However, the instructions are commented
out so that the command procedure fails if an attempt is made to use it
before it is updated. These DEPOSIT commands must be changed to
conform to your system'’s configuration. Changing the deposit to R3 is
optional; leaving it commented out lets you provide the unit number in
the BOOT command. That makes booting more flexible. The deposit to
R5 under certain circumstances must be modified. This command can be
commented out if you wish to supply R5 data in the BOOT command.
Use the following chart to determine which bits must be set in each
register. The syntax <‘nninn_> indicates the bits to modify. For instance,
“207:00
>

means bits 0 through 7. Bits are numbered from left to right in

the longword, starting at 0. MBZ means Must Be Zero. The configuration
information can be obtained from DIGITAL Field Service.

which you wish to boot (BDA, UDA or BCI).

Py vour system has similar devices on a Bl that use the same device driver. you must ensure that the

controller letter is specified in R2 if vou wish to boot from any device other than the first one on the Bl
If. for instance, you have two BDA devices on the same Bl and you wish to boot from the BDA at the
higher Bl node number, then R2 must contain the controlier letter of the BDA in the high-order byte.
The value placed in this byte overrides the YMS initialization time assignment of controller letters.

“ A BDA device requires no inputs to R2 other than the optional controller letter designator.

“E” must be deposited into R5.

in addition to the boot files described, vou receive a template for

DEFBOO.COM, the default boot file. That file is executed when a BOOT
command is entered without a device name or when vou enable AUTO_
BOOT, and the system reboots due to a power failure or error halt.
DEFBOO.COM consists of a single command, a BOOT command. You
must modity the device name to refer to the command file you have
set up to boot your system.

For instance, if you wish to boot from a

device on the BCI750 with a unit number of 2, you would modify the
DEFBOO.COM BOOT command from:

[

BOH

When DEFBOO.COM is executed, it starts the execution of BCIBOO.COM

and deposits a 2 in R3. Successful completion depends on the prior editing
of BCIBOO.COM. This assumes that you commented out the R3 deposit
in BCIBOO.COM and that you have set up RI, R2, and, in this case, R5
(to specify for the system boot) correctly.

Editing a Boot File
To edit the boot files, you must be at the PRO/DCL command level and
in the proper directory. (See Section 3.5 for a description of the system
directories.) If vou are in console command mode, type EXIT to enter

PRO/DCL. The $ prompt will appear.
You can make copies of the templates so that they will be available later.

To do this, enter the following command, replacing ddd with a valid
device mnemonic as specified above for each file you wish to save:
§ COPY dddBOO.COM dddBOO SAV
After you have“saved” the templates, you can edit the command files. To
do this, use the EDT editor provided with P /O5.

§ RUNEDT
> 44dBOOCOM
EDT
The P/OS EDT editor automatically enters command mode, where you
have both kevpads (main and auxiliary) available for editing purposes.
Refer to Figures 4-2 and 4-3 for illustrations of the LK201 keyboards.
This editor is a subset of the VMS EDT editor. Refer to the VMS EDT
editor documentation for more information. To obtain on-line help for
EDT, press the PF2 key after you have started the editor.

Console Commands
The Console Command Language (CCL) is the set of commands you use

to control and monitor the VAX from the console. This chapter describes
each command, including its structure, syntax, parameters, qualifiers,
options, and restrictions. Examples of each command are also provided.

5.1

.fi

Commands

A command is usually a verb that describes the action the console program

is to take. For example, typing DISABLE PRINTER stops all console
output to the printer.

Commands must be contained on one line and can be a maximum of 120
characters. Adjacent spaces and tabs are equivalent to a single space or
tab.

5.1.1

Parameters
Parameters are always preceded by a space. They describe the object of
the command, which can be a file, an address, a bit offset, a command, a

count, or some data. For instance, the following MICROSTEP command
parameter specifies the number of microcycles to step:

If a command parameter is a file name, the syntax is always in Files-11

format:
filenarme.extension;version

Console Commands

5-1

where:

filename = any name up to 9 characters
extension = a 3-letter extension to the file name
version = number assigned by the Files-11 file system
Allowable characters are A through Z and 0 to 9.
Device names are not allowed. Any file name specified must reside on the
fixed disk, DW1:. Files may reside in the following directories:
VAX 8800 - [CONSOLE] or [8800]
VAX 8700 - [CONSOLE] or [8700]
VAX 8550 - [CONSOLE] or [8550]
VAX 8500 - [CONSOLE] or [8500]
You cannot specify a directory as part of a file name.

5.1.2

Options
An option is a keyword used with a command.

For example, AUTO

RESTART and AUTO BOOT are options used with the ENABLE com-

‘

mand. You are usually required to specify one option.

5.1.3

Qualifiers
A qualifier is a command argument preceded by a slash (/) that causes the
command to perform a more specific action. For example, the /NEXT=n

qualifier used with the DEPOSIT command causes the command to repeat
10 times at successively higher addresses:
DEPOSIT/NEXT=10 address data

Qualifiers are used with commands and parameters. You may leave a
space between the command (or parameter) and the qualifier but not
between the slash (/) and the qualifier.

5-2 Console Commands

‘

5.1.4

Defaults
A default is a value automatically used by the system when you do not
enter another value. Commands have defaults that take effect when
the console application is installed. Defaults are either reinitialized each
time the console is powered up or retained across power failures. Some
defaults are initialized each time a new command is invoked. Defaults
and qualifiers for commands are included in their descriptions.

5.1.5

Command Abbreviations
Commands and qualifiers can be abbreviated as long as the abbreviation
containe enough characters to identify it uniquely. The briefest command
form appears in Appendix A in bold lettering.

5.1.6

Command Terminator
Any command can be terminated before execution with CTRL/U.

5.2

Syntax Error Reporting
The console reports syntax errors by displaying the command line just

read (either from the terminal or command file) and the words “INVALID

COMMAND SYNTAX". Error messages are described in Appendix C.

5.3

The Command Language
The following tables describe how symbols, prompts, and special keys are

used in the command language.

Console Commands

5-3

53.1 Symbols

Definition

A slash indicates a command qualifier.

No space 1s allowed

between the slash and the qualiher.
+

A plus sign denotes a default address, which is the last address
plus the current data length in bytes.

A minus sign denotes a location just before (one less than) the
address previously referenced.

©@

When used in place of an address or data argument, the at sign
indicates that the data returned from the last reference to an

address should be used as the current address or data.
at sign is also used to execute command procedures.

The

When

used as a data argument, the data of the previous EXAMINE or
DEPOSIT command is copied into the specified address.

(See

descriptions of the EXAMINE and DEPOSIT commands for more
information.)

*or.

When used as an address argument, the asterisk or period
indicates that the lust address referenced is to be used again.

The comma separates items in a list.

= Of :

The equal sign or colon separates a qualifier from an associated
argument. For example, /NEXT=n or /NEXT:n may be used.

CTRL/C

Aborts activity in progress.

CTRL/S

Stops the screen from scrolling. See CTRL/Q.

CTRL/Q

Allows the screen to resume scrolling. See CTRL/S.

CTRL/U

Aborts input without executing it. On the remote port,

CTRL/U must be followed by Return in order to obtain
a new prompt.

CTRL/Z

Terminates and executes the command line.

(Fundctionally equivalent to pressing Return.)
Deletes the character to the left of the cursor and moves

the cursor one space to the left.

Hold Screen

Freezes a screen display so you can read it.

Press the

key again to release the hold. When Hold Screen is in
effect, its indicator light (top of the keyboard) stays on.
Print Screen

The Print Screen key causes the current image on the

screen to be printed. Certain types of graphics images

cannot be printed with Print Screen. Print Screen also
executes a Hold Screen (see Caution below).
Print Screen is disabled when the printer has been

enabled with the ENABLE PRINTER command.
Return

The Return key terminates and executes a command
line.

Set-Up

Pressing Set-Up unlocks a locked keyboard. If nothing
happens when you type on the keyboard, check to see
if the Wait light at the top of the keyboard is lit. If
the Wait light stays on for more than 15 seconds, the
keyboard is probably locked. You may be able to unlock
it by pressing the Set-Up keyv once. Some applications

intentionally lock the keyboard for brief periods, and
you need to wait. Pressing Set-Up may affect the
program running on the VAX.

Console Commands

5-5

CAUTION
Hold Screen causes program mode output to be lost. To prevent
this, use CTRL/S to hold the screen and CTRL/Q to release it.

5.4

Console Command Descriptions
The remainder of this chapter describes each console command in detail. The commands are ordered alphabetically. Parameters, options, and
qualifiers associated with the command are described. Micromonitor commands, which enable you to use the diagnostics program, are described in
Chapter 6.

On the VAX 8800, some commands apply only to the CPU whose output
is on display, while others affect both CPUs. The scope of multi-CP'U and
single-CPU commands is specified by SET CPU, which is described in this
chapter. The description of each command indicates the CPU to which

the command applies. See Section 3.2 for more information.
Multiple CPU commands (those referencing Primary, Secondary, Left, and
Right CPUs) do not apply to the VAX 8700, 8550, or 8500.

Help
Information about each command can be accessed on-line by entering the
following at the console (*» > >~

) prompt:

HELP command-nanie

To get a listing of HELP topics, just enter HELP.

5-6

Console Commands

@
Executes console commands contained in a command procedure.

Format

@file-name

Description
The command procedure specified by the parameter file name is opened.

Records in the file are processed as sequential console commands. When
@ is invoked from a command file, the original command file is closed and
the new (specified) file opened. When the new file terminates, processing
stops. (Execution does not return to the previous file.) This command
allows chaining of one command procedure to another, but not nesting of
command procedures inside each other.

If VERIFY mode has been set, the console displays each line as it is read
from the command file, as well as the response to each command &= it
is executed. If VERIFY mode has not been set, lines from the file are not
echoed. (See SET VERIFY and SET NOVERIFY command descriptions.)

To terminate execution of a command file, press CTRL/C. Control returns
to the terminal.

Command Parameter
file-name

The file name specifies the command file to be opened. The file can be
any valid FILES-11 file specification that identifies a sequential ASCII file.
If the file extension is not supplied, .COM is assumed.

BOOT
Executes a command procedure that starts the VAX operating system

software.

Format

BOOT

[device-name]

Command Qualifiers

Defaults

/RS : data

None

Description
BOOT executes the command file device-nameBOO.COM. If no device
name is specified, the file DEFBOO.COM is used.

Command Parameter
device-name
Specifies the name of the device from which the operating system
is to be loaded and run. If no device name is specified, the default
device is booted as specified in the default boot command procedure
DEFBOO.COM. Device-name uses the syntax dddnnn where:
ddd is a 3-letter device mnemonic (valid devices are BCI, BDA, UDA).
nnn is an optional 1- to 3-digit unit number.
The wnit number is picked up from the parameter device-name by the
console and deposited into R3 prior to execution of the boot file devicenameBOO.COM. Any deposit to R3 contained in the boot file overrides
nnn in device-name. Therefore, the DEPOSIT R3 command in the boot

command file can be commented out if greater flexibility is desired in
choosing a unit to boot.

Console Commands

5-9

BOOT

Command Qualifiers
/R5 : data
Deposits the specified numeric literal in R5 before the command file is

processed. This mechanism passes information to the primary bootstrap
program (VMB). (See Appendix D for valid data.) If the /R5 : data
qualifier is used, the DEPOSIT R5 comniand in the boot command file
must be removed or commented out.

CLEAR RESTART_FLAGS

Description
The COLD_RESTART flag is set by the FIND/MEM command, which

is used in the BOOT command procedure. The WARM_RESTART flag
is set by the FIND/RPB command, which is used in the RESTAR.COM
command procedure. The VAX operating system clears the COLD_
RESTART and WARM _RESTART flags following a successful boot or
restart. If the boot or restart fails, these flags remain set to prevent
automatic boot and restart procedures from looping indefinitely. The
CLEAR RESTART_FLAGS command can be used to manually clear these

flags so that a subsequent BOOT command will execute. It is used as the

final command in the SYSINIT.COM procedure.

Restriction
Use caution when including CLEAR RESTART_FLAGS inside command
files.

Under certain error conditions, the command files may execute

indefinitely.

Description
The DEPOSIT command can replace the contents of a location(s) in

memory, CPU registers, cache, translation buffer, control stores, IPRs,
GPRs, or I/0 space.

Defaults

If no data size or address space qualifiers are specified, the defaults are
established by the most recent EXAMINE, DEPOSIT, or SET DEFAULT

command. {Note that the EXAMINE command does not change the
default address space when examining the PLS or the UPC))

5-18

Conscle Commands

DEPOSIT
Initially, the default is LONGWORD data size, PHYSICAL address space,
address identifier 0, and radix hexadecimal.

Restrictions

The CPU must be halted.

After the WCS is loaded (see the /WCS qualifier description), you
cannot deposit (or examine) the Slow Data File (SDF).

You cannot use the /GPR or /IPR qualifier when specifying a symbolic
address.

The size qualifiers /BYTE, /WORD, and /QUADWORD are valid

only with physical and virtual address spaces. However, if the size
qualifiers are used with any other address spaces, the qualifiers are
ignored and /LONGWORD is used instead. The default size changes

to /LONGWORD.

. Command Parameters
address-identifier
Specifies the starting numeric or symbolic address of a location or series
of locations whose contents are to be replaced with deposit-data. The
numeric address is a numeric literal. (See Appendix B.)

deposit-data
A numeric literal that defines the data to be deposited into the specitied
location(s). If deposit-data is specified as @, the last data examined is used

as the deposit data. (See the description of the EXAMINE command.) The
DEPOSIT command writes the data in consecutive locations, beginning
with the address specified. (See Appendix B.)

Console Commands

5-19

DEPOSIT
Command Qualifiers
/NEXT

Causes the DEPOSIT command to be repeated n times, with successively
higher addresses. The amount of address increment/decrement depends
on the size qualifier (see below). For GPRs and IPRs, the address
increments by one. The same data is deposited into each location.

The DEPOSIT command continues either until the command has been

repeated n times or until address overflow occurs. Address overflow
occurs when the GPR number exceeds 15(decimal) or the IPR number
exceeds 255(decimal).
address-space-qualifiers
The following qualifiers mav be used on any DEPOSIT address to override
the default address space setting.

/CACHE
Cache data store.

/CONTROLSTORE or /WCS
The address is to be interpreted as a Writable Control Store (WCS)
address.

/GPR
/GPR indicates that the address is to be interpreted as the number of a
YAX General Purpose Register (GPR). The GPR number must be between

0 and 15(decimal). If /NEXT=n is specified and the GPR number exceeds
15, the command terminates with an address overflow error.

/IPR
/IPR specifies that the address is to be interpreted as the number of an
Internal Processor Register (IPR). The IPR number must be in the range
0 to 255 (decimal). If the /NEXT=n qualifier is specified, and the IPR

number exceeds 255, the command terminates with an address overflow
error.

/PHYSICAL
The address space is to be in physical memory or physical 1/O space.

/SDF
Slow data file.

5-20

Conscle Commands

DEPOSIT
/TB
Translation buffer.
/TEMP

IPRs known only to microcode, not macrocode. See Appendix B. Only
numeric literals are valid with the /TEMP qualifier.

/VIRTUAL
Interprets the address as a virtual address. Access and protection checking
occurs. If access is not allowed, the console issues an error message.

If memory management is not enabled, virtual addresses are equal to
physical addresses.

size-qualifier
Use the following qualifiers to specify data size. The initial default data
size is LONGWORD. The qualifiers

/BYTE, /WORD, and /QUADWORD
are valid only on /PHYSICAL and /VIRTUAL address spaces. If /B, /W,

and /Q size quahfiers are used with any other address spaces, they are
treated as /LONGWORD and the default is changed to LONGWORD.

/BYTE
References a 1-bvte quantity.

/WORD
References a 2-byte quantity.

/LONGWORD
References a 4-byte quantity.

/QUADWORD
References an 8-byte quantity.

Console Commands

EXAMI

P - Physical memory: When examining virtual memory, the address
space and addressin the response are translated to ph} sical addresses.
The EXAMINE command normally changes the default address space,
except when examining the PSL or UPC.

The address is displayed in hexadecimal, right justified, and zero filled
to the actual address magnitude. The contents-of-address is displayed in
hexadecimal, regardless of default settings.

The address-space and size qualifiers default to the values or radixes
used in the previous EXAMINE, DEPOSIT, or SET DEFAULT command.
Initially, the default is LONGWORD data size, PHYSICAL address space,
address identifier 0, and radix hexadecimal. The size qualifiers /BYTE,
JWORD, and /QUADWORD used with any address-space qualifier other
than /PHYSICAL or /VIRTUAL reset the size-qualifier to LONGWORD.

The CPU must be halted.

Do not use the /GPR or /IPR qualifiers when using a symbolic register
address. (See Appendix B for the symbolic addresses.)

After the WCS is loaded, you cannot examine (or deposit) the Slow
Data File (SDF).

The /BYTE, /QUADWORD, or /WORD sizes are valid only with the
/PHYSICAL and /VIRTUAL address-space-qualifiers.

language symbols.) The numeric address is a numeric literal. (See
Appendix B.)

Command Qualifiers
/NEXT=n
Causes the EXAMINE command to be iepeated n times at successively
higher addresses. The amount of address increment /decrement depends
on the size qualifier (see below). For GPRs and IPRs, the address
increments by one.
The EXAMINE command continues until the command has been repeated

n times or until one of the following access errors occurs:

The GPR number exceeds 15(decimal).

The IPR number exceeds 255(decimal).

address-space-qualifiers
The following qualifiers may be used on any EXAMINE address to
override the default address space setting.

/GPR
/GPR indicates that the address is to be interpreted as the number of a
VAX General Purpose Register (GPR). The GPR number must be between
0 and 15 (decimal). If /NEXT=n is specified and the GPR number exceeds

15 {decimal), then the command terminates with an address overflow
error.

/IPR
/IPR specifies that the address is to be interpreted as the number of an
Internal Processor Register (IPR). The IPR number must be between 0 and

255 (decimal). If the

/NEXT=n qualifier is specified and the IPR number

exceeds 255 (decimal), the command terminates with an address overflow
error.

‘

FIND
/MEMORY command sets the COLD._RESTART flag. If another FIND

/MEMORY command executes before the RESTART command completes
or boots the system, the second command fails, because the COLD_.
RESTART flag is still set. When the operating system successfully boots,
it sends a message to the console to clear the COLD_RESTART flag.
To clear the COLD_RESTART flag and boot manually, use the CLEAR
RESTART_FLAGS command.
_

The FIND/MEMORY command is in the boot command procedures

- DEFBOO.COM and device-nameBOO.COM.
/RPB
Requests a search of physical memory for a valid restart parameter block,
which is used to restart the system after a power failure or error halt.

The stack pointer is loaded with the RPB (starting address + 512) and the
PC is loaded with the contents of RPB (starting address + 4). The search
leaves the contents of memory unchanged. To prevent the console from
repeatedly frying to restart the system, the FIND/RPB command sets

the WARM_RESTART flag. If another FIND/RPB command is executed

before the RESTART command completes or the system successfully
restarts, the second FIND/RPB command fails because the WARM__

RESTART flag is still set. When the operating system successfully restarts,
it sends a message to the console to clear the WARM_RESTART flag. To
clear the WARM_RESTART flag and restart the system manually, use the
command CLEAR RESTART_FLAGS.
The FIND/RPB command is in the command procedure RESTAR.COM,
which is executed automatically after a power failure or error halt if
AUTO_RESTART is enabled.

IF[NOT] state-bit-name THEN console-command

Description
The IF command conditionally executes console commands. The conditional execution is based on one of the console state bits. Each state bit

has a mnemonic, all of which are defined in Appendix B. The state bits are
set by console commands or console software.
The success or failure of the console previous command is reflected in
the state bit mnemonic $5TATUS. (The IF command itself does not affect

$STATUS.) If the console-command is an “@” command, another stream
of console commands follows. The use of “@” commands and $STATUS
and other state bits allows complicated sequences, such as the initialization
sequence, to be expressed in command files.

Command Parameters
state-bit-name
Each state bit is expressed by a mnernonic.
console-command
Any valid console command

[MEMORY

INITIALIZE is used to bring the hardware to a known consistent state.

It causes the console support microcode to execute and enables the
micromachine. The INITIALIZE command without qualifiers copies the
value of NEXT_PRIMARY to CURRENT_PRIMARY.

For a VAX 8800, INITIALIZE applies to selected and available CPU(s).
The CPU clocks are left on. Traps, stalls, and the Nautilus Memory
Interconnect (NMI) microsequencer are enabled.
The INITIALIZE command can halt a CPU under certain conditions. If it
does, a warning appears.

The CPU(s) must be halted.
To insure that the revision Internal Processor Registers (IPRs) are properly

filled in by INITIALIZE, the following commands must be executed prior
to INITIALIZE:

SENSE REV CPU
Heads and stores revisions of CPU modules, CLK, and CPU
backplane.

Data is loaded to the Slow Data File, which requires that the CPU(s)
be halted.

Command Qualifiers
JCREATE_CONFIGURATION_FILE
Creates a MEMCONFIG.DAT file, which contains the interleaved map of
the physical address space to physical memory. This file is based
on the
memory arrays present when the command is executed. This qualifier
must be used prior to the /MEMORY qualifier in order to create an initial
{or new) MEMCONFIG.DAT file. That is done during the first startup
procedure (see Section 4.3) and when you add or remove memory arrays
{see Section 4.8).

Console Commands

5-63

/MEMORY
This qualifier causes the console to load the MEMCONFIG.DAT file into
the memory controller’'s decode RAM. If the memory controller’s cold bit is
set, indicating that the memory is invalid, physical memory is initialized to
zero with good parity. If the console cannot find the MEMCONFIG.DAT
file, it creates a new one and notifies you with a message.

NOTE

If mémory is added or removed, the command INITIALIZE
/CREATE _CONFIGURATION _FILE and INITIALIZE
/MEMORY must be executed before you attempt to reboot
your system.

LINK

Description
LINK is used for repeatedly executing a series of console commands.
After building the temporary command procedure LINK.COM, execute it
with the PERFORM command. (The @LINK command is equivalent to
this.) The temporary command procedure remains until the next LINK

command is executed, replacing the previous command procedure with
the new commands.
When LINK is entered, the console deletes the previous LINK command
procedure and prompts with the link-mode prompt (< < <) . Console
commands are saved in the temporary file LINK.COM (on the console’s
hard disk) until CTRL/C is entered. Renaming this file saves it. It can

also be edited with an editor running under P/OS.

Restriction

The PERFORM command is invalid inside a file created by the LINK

. Description
The LOAD command is used by the system initialization routine to load
the Writeable Control Store (WCS), Instruction Stream Decode Rams
(IBDECODER), Slow Data File (SDF), and CACHECONTROL store.

NOTE
Failure of the LOAD command can mark a CPU unavailable.

Defauits
If no qualifiers are specified, the command defaults to loading main

memory (/MAINMEMORY), starting at physical address 0 (/START=0j.

Console Commands

5-67

LOAD
Restrictions
The LOAD data comes either from a file or the command line (expressed
as a numeric literal-see Appendix B. Supply either a file name or the
/DATA qualifier. (See Command Qualifiers.)

The CPU must be halted and the CPU clocks running. (See the SET

CLOCK command or SHOW STATUS.) To load main memory or the Slow
Data File (see /SDF), the CPU must be halted.
Files of control-store data must be in the correct format for the particular
control-store specified in the LOAD command. If the Writeable Control
Store (/WCS), Instruction Stream Decoder Rams (/IBDECODER), Cache
Control Store (CACHECONTROL), or Slow Data File (/SDF) is loaded
from a file, the header block of the file is checked for the following
compatibilities:

The file is the same type of control store to which it is to be loaded.

The revision level of the file is the same as the previous file's level
loaded into that control store since the last time the console was
powered cn.
The /DATA qualifier and file name parameter cannot be used at the same
time.

Command Parameter
file-name
Name of the file containing the data to be loaded. It can be any valid file
name, including device and directory. The console device names are DW1
(fixed disk) and DZ1 and DZ2 (diskette drives 1 and 2).

Command Qualifiers
/CACHECONTROL
The destination is the cache control store. LOAD/CACHECONTROL

applies to selected and available CPU(s). If a parity error is detected, the
CPU is marked unavailable.

5-88

Console Commands

LOAD
/CONTROLSTORE or /WCS
The destination is the WCS. LOAD/WCS applies to selected and available
CPU(s). If a parity error is detected, the CPU is marked unavailable.

/DATA=numeric-literal
A single element of the control store or memory is loaded. You enter data

on the console terminal and load the data into the destination indicated
by the qualifier designating the address space and the /START qualifier
indicating the address in that address space. (See Appendix B.}
If loading main memory, the data is assumed to be a longword. If loading
a control store, the data is assumed to be the correct length for that control
store. Maximum sizes are as follows:
IBDECODER (or DRAM): 24 bits

CACHECONTROL (or CCS): 32 bits
SDF: 32 bits
MAINMEMORY: 32 bits

/IBDECODER
The destination is the instruction stream Decoder RAMs.

LOAD

/IBDECODER applies to selected and available CPU(s).

/MAINMEMORY
The data’s destination is main memory. This qualifier requires the CPU(s)
to be halted.

/SDF
The data’s destination is the Slow Data File, which requires that the

CPU(s) be halted. LOAD/SDF applies to selected and available CPU(s).

/START=numeric-address
The data is loaded, starting at the address specified. The address is
expressed as a numeric literal (see Appendix B).

If the /START qualifier is omitted, data is loaded at address=0 of the load
destination. /START is ignored if loading microcode or SDF (valid when
loading memory) from a file, because the address(es) are embedded in the
file.

Console Commands

5-69

JUWCS
You use the

/UWCS qualifier to load your own microcode into the User

Writable Control Store (UWCS). You can do this only if SDF has been

loaded. The system initialization procedure SYSINIT.COM provides the
commands to enable you to do this (though they are commented out).
The VAX Extended Function, XFC, instruction provides the mechanism for
software to request services of the nonstandard microcode loaded into the

UWCS.

Steps the CPU master clock a specified number of cycles.

After Steppmg the specified number of mxcrocycles the console displays

the micro-PCs of available CPU(s) and enters“space bar step mode”.
On the VAX 8800, subsequent pressing of the space bar causes another
microcycle to be executed on both CPU(s). Space bar step modeis exited
by pressing any key other than Spacebar or Return. The micro-PCs of the
available CPU(s) are displayed.
The micro-PCs are displayed in hexadecimal.

NOTE
The micro-PCs on the VBUS are those of the trap silo, not the
actual micro-PCs. Therefore, single stepping through a trap
routine or decoder cycles does not change the micro-PCs.

Restrictions

The CPU clock(s) must be stopped. (See the SHOW STATUS and/or
SET CLOCK commands.) The console will automatically stop the clock(s)
unless a CPU is running.

If MICROSTEP is executed from a command file, “space bar step mode”
(see Microstep command) is not entered. Control returns to the command
file after the initial number of microinstructions have executed.

Format

POWER (option)

Description
One of the following options must be used with the POWER command:
OFF, ON, STANDBY. The options are described as individual commands.

WARNING
If it is necessary to work on the CPU, you must issue the

POWER OFF command and shut off the main power breaker
of the CPU. The following safety feature is designed to protect
those working on the system hardware:
When you issue the POWER OFF command, the console saves
the contents of the AUTO_POWERON keyswitch and disables
it. Then with any kind of power failure (including turning
off the console), the initialization procedure (SYSINIT) detects
that the AUTO_POWERON keyswitch is disabled and does
not power up the system. That prevents a console-only power
failure, for instance, from powering up the entire system.
When the work on the system hardware is finished, turn on
the circuit breaker and issue the POWER ON command. The
AUTO_POWERON keyswitch value is restored to its setting

prior to the POWER OFF command.
If you have enabled the AUTO_POWERON keyswitch and
have not issued a POWER OFF command, the console responds
to power failures automatically. If the circuit breaker is then
inadvertently turned on, the console automatically powers
up the system, endangering those working on the system
hardware.

SHOW REVISION
Displays revisions of VAX modules.

Format

SHOW REVISION

(option)

Description
The SHOW REVISION command displays current or historical revision
data in a hierarchical fashion. Each system component has a revision
level. Low-level revisions are combined to form a revision level for a
group. Group-level revisions form a kernel (top-level) revision.
Revisions are used to insure that hardware, software, and their combinations are valid.

Default
If no option is specified, the default is SHOW REVISION SENSED ALL.

Command Options
HISTORY
[ALL, CONSOLE, CPU, KERNEL, MCL, MICROCODE, NBI]
SHOW REVISION HISTORY displays the contents of the revision history
file REVHIST.DAT. The revision history file defines top revisions and
compatibility between revisions and top revisions. The display shows the
revision range of subordinate components that make up a top revision.
The revision of the history file is displayed as File rev n.
The display is segmented into sections that describe the range of top revisions for each top revision group. The top revision groups are CONSOLE,
CPU, KERNEL, MCL, MICROCODE, and NBI. Under each segment, the
values of the top revisions for a given group are displayed across the
page and labeled Rev 1, where # is the value of the top revision. Under

SHOW REVISION

each top revision, a column of subordinate components is listed, with the ‘
minimum and maximum required component revision for that top revision
(labeled min and max). The top revision sections also comprise the following options of the SHOW REVISION HISTORY command. If none of
these options are used, the default is SHOW REVISION HISTORY ALL.
*

ALL-displays the revision history for hardware and software components.

CONSOLE-displays console revision information.

CPU(S)-displays revision information about the CPU(s).

KERNEL-displays the revision history of top-level revisions for components, including the CPU, console, Memory Controller (MCL),
microcode, and NBL

MCL-displays revision information about the Memory Controller.

MICROCODE-displays revision history about the microcode.

NBI-displays revision history about the NBI.

SENSED
[ALL, CONSOLE, CPU, KERNEL, MCL, MICROCODE, NBI]

SHOW REVISION SENSED displays the revisions of modules sensed

with the SENSE command, the kernel software components, and the top
revisions that have been calculated by the VERIFY REVISION command.

‘

SHOW REVISION SENSED does not actually cause the revisions to be
read or calculated. The command accepts qualifiers that limit the display
to a specified revision group.
Items in the Component column identify the component or top revision.
A top revision is calculated by the console from the revisions of one or
more individual components. Indentation of a component name indicates
that it is subordinate to a top revision. Top revisions are calculated when

the VERIFY REVISION command is executed.
For the VAX 8800, the value of top revisions and components are dis-

played under the columns labeled Left CPU, Right CPU, and Common.
(The VAX 8700, 8550, and 8500 columns are labeled CPU and Common.)
Some components, such as CPU logic modules, are unique to a CPU.
Since these components and top revisions might have components with

different revisions in each CPU, the components are displayed under
the Left CPU or Right CPU columns. Components that are not unique
to either CPU, such as console software, are displayed in the Common

column,

5-124 Console Commands

‘

SHOW REVISION
A revision for an individual component is displayed as a number or a
letter. If a component is “unavailable”, that component has not yet been
sensed.

Top revisions are expressed as a number, flagged as unavailable, or undefined <"n.>. When a number is displayed, the top revision has been
calculated through the associated VERIFY REVISION command. The
information is stored in the revision history file. The flag “unavailable”
indicates that the VERIFY REVISION command has not yet been successfully executed to determine a top revision. The flag “undefined <n> "
indicates that the revisions of the subordinate components do not match
any top revision described in the revision history file. The <n> is
the closest top revision in the revision history file, based on the sensed
revisions of the subordinate components.
The Comments column displays information about the component revision

status. “Not calculated” or “Calculated” refers to whether the VERIFY
REVISION has been successfully executed to determine a top revision.

“CPUs mismatched” on a VAX 8800 is a warning that differences occur in
top revisions of the CPUs, which violates a VMS compatibility rule. “Not
sensed” indicates the revision is unavailable, because the SENSE command
for that component was not executed or failed to read the component’s
revision.

SHOW REVISION SENSED has the options listed below. The default is
ALL.
*

ALL - displays sensed revisions for all components.

KERNEL - displays the revisions of all top-level components groups
sensed with the SENSE command. These component groups include
console, CPU, MCL., microcode, and NBI.

CONSOLE - displays revisions of the console sensed with the SENSE
command and /or calculated by the VERIFY REVISION command.

CPU(S) - displays revisions of CPU(s) sensed with the SENSE command.

MCL - displays revisions of the memory controller sensed by the

SENSE command and/or calculated by the VERIFY REVISION command.
e

MICROCODE - displays revisions of the microcode that were remembered when the microcode files were loaded.

NBI - displays revisions of the NBI sensed by the SENSE command
and/or calculated by the VERIFY REVISION command.

None

Description
START applies to selected and available CPU(s).
If the

/CONTROLSTORE or

/WCS qualifier is not entered, START

executes macrocode. If the /CONTROLSTORE or /WCS qualifier is
provided, START begins execution of microcode.

Restriction

The clocks must be stopped prior to issuing this command. (See the

SHOW STATUS and/or SET CLOCK commands.)

Command Parameter
address
Specifies the address at which execution begins. The address is expressed
as a numeric literal, the special address symbol @, or the symbolic name

CSM_INIT (see Appendix B). When the address is specified as a numeric
literal, the macro-PC is set to the specified address, and a CONTINUE
command is automatically executed.

When the @ symbol is used as the starting address, the data pointed to by
the last EXAMINE or DEPOSIT command is taken as the address.
If no address is specified, a CONTINUE command is executed, and
execution begins at the current macro-PC.

5-132

Console Commands

Command Qualifiers
/CONTROLSTORE or /WCS
Execution begins at the Writable Control Store (WCS). The micro-PC is
loaded into the micro-PC register, and microcode execution is initiated
by starting the clock. The starting address CSM_INITis used with the

/CONTROLSTORE or /WCS qualifiers. Starting the microcode at this
address initializes the micromachine to a known state.

Numeric and Address Data
This appendix provides the numeric literals and symbolic addresses
referred to in Chapters 5 and 6. The state bit definitions and the Internal

Processor Registers descriptions are also listed.

B.1

Numeric Literals

A numeric literal can be specified in any base by using a radix specifier.

The default radix is set with the SET DEFAULT command and displayed
with the SHOW DEFAULTS command.

Table B-1:

Radix Specifiers

Radix

Specifiers

Definition

Numeric literal interpreted and verified as OCTAL.

Numeric Iiteral interpreted and verihed as HEXADECIMAL

%D s

Numeric literal interpreted and verified as DECIMAL.

% B -

Numeric literal interpreted and verified as BINARY.

The maximum size of a numeric literal depends on its context.

For
example, micro-PC addresses may not exceed 14 bits, physical and virtual

addresses may not exceed 32 bits, and the size of the EXAMINE or
DEPOSIT commands data may not exceed the size qualifier.

Numeric and Address Data

B8-1

The default radix is initially hexadecimal. Using a radix specifier changes
the default radix.

B.2

Symbhoelic Addresses
The console supports a set of symbolic addresses to facilitate use of
the EXAMINE and DEPOSIT commands. The symbolic addresses are
expressed as mnemonics, symbolic IPR names, and special addresses.
When symbolic IPR and GPR names are included in a command, the
command qualifiers /IPR and /GPR must be omitted. When a mnemonic
or symbolic address is specified, it is translated into a numeric address
value, an implicit size, and an implicit address space.

Installing
the Console Software
Your console is actually a computer with an operating system (P/OS5)
and application software. This software is separate from the VAX operating system and application software running on the VAX system.
The console’s operating system and required application (PRODCL, 'RO
/Communications) have been installed on your console’s hard disk at
the factory. Under most circumstances, you do not need to reinstall software on the console. However, if your console experiences software or
disk problems, you must reinstall the operating system and/or applications. Detailed instructions for installing the P/OS operating system,

PRO/Communications, and Console/PRO DCL application are provided
in this appendix.

Before installing console software, make certain that your hardware
components are correctly installed (see the System Hardware User's Guide)
and check with your DIGITAL Field Service representative.
Read the following before installing console software:
®

To choose a menu item, use the arrow keys to place the pointer and
press DO.

To insert diskettes, push the drive doors to open them. Insert the
diskettes, lining up the arrows on the drive with those on the diskettes.
Close the drive doors.

Device names of diskette drives 1 (top) and 2 (bottom) are DZ1: and
DZ2: respectively. The fixed disk device name is DW1.

very siimilar for the VAX 8700, 8550 and 8500, except for commands that
involve dual CPUs. The SET VERIFY command can be used to display
the commands in these files as they are invoked.

SECBO00.COM, Secondary Processor Boot Command Sequence VAX 8800
On the VAX 8800, the main difference between the Primary and
Secondary CPUs is that the Secondary never actually“boots.” A “boot”
in the Secondary CPU is implemented as a restart. The Secondary never
needs to initialize its state from scratch. The Secondary uses a restart
parameter block (RPB) that the Primary built and put into memory for the

Secondary to find. The console reboots the Secondary when requested by
the Primary (provided the command DISABLE SECONDARY has not been
issued), using the SECBOO.COM command file. The following commands
are in SECBOO.COM:
