The console security feature allows you to disable most of the system console
commands. When the security password is set, there are two types of users:
privileged users and unprivileged users. Privileged users know the security
password and can use the full range of console commands; unprivileged users
can use only the following commands:
•

•

BOOT—Use this command without parameters to boot the operating
system.

•

CONTINUE—Use this command to return to the operating system after
pressing the halt button.

enter the same security password at each prompt, the system saves the
security password in nonvolatile memory. The system does not lose the
security password when you turn off the system.
If the second security password does not match the first, the system
responds with the following error message:
?63 ILLEGAL PASSWORD
>>>
4. Repeat steps 1 to 3 if you see an error message.

2.2.2 Enabling the Console Security Feature
When you have set the security password, you must enable the console security
feature. To enable the console security feature, enter the following command at
the console prompt:

2.2.6 Exiting from Privileged Console Mode
When you exit from privileged console mode, privileged users must enter the
LOGIN command with the correct password before they can use the full range
of console commands. To exit from privileged console mode, enter one of the
following commands:
•

BOOT (with any supplied parameters)

•

CONTINUE

•

HALT

•

START

Chapter 3 describes each of these commands.

2.3 Setting the Default Boot Device
When the system is shipped, it is set to boot from the system disk, DKA300.
This RZ-series disk holds the factory installed software (FIS).
You can set the system to boot from a different default boot device that holds
the operating system software. Table 2–1 shows the alternative default boot
devices and their associated OpenVMS™ device names.

Console Security Feature and System Defaults 2–7

1 x represents either A or B, determined by the SCSI port used by the device.
2 n represents the SCSI ID of that device.

To set an alternative default boot device, enter the SET BOOT command using
the OpenVMS device name of the alternative default boot device. For example,
to set the system to boot over the network, enter the following command:
>>> SET BOOT EZA0

2.4 Setting the Default Recovery Action
There are five default recovery actions. You can change the default recovery
action by entering the SET HALT command and the value or keyword
associated with the action you want to set. Table 2–2 shows the five default
recovery actions and their associated values. When the system is shipped, the
default recovery action is set to halt.
Table 2–2 Default Recovery Actions and Associated Values

halts.

HALT

The system halts and displays the console
prompt.

RESTART_REBOOT

The system tries to restart the operating system.
If it fails to restart the operating system, it tries
to boot. If it fails to boot, it halts.

2–8 Console Security Feature and System Defaults

To set an alternative default recovery action, enter the SET HALT command
using the value or keyword associated with the recovery action you want to set.
For example, to set the system to halt, enter one of the following commands:

Console Commands
This chapter describes the console commands that you can enter when the
system is in console mode. The system displays the console prompt (>>>) when
it is in console mode. If the system is running the operating system software,
see Chapter 2 for information on returning the system to console mode.
If the console security feature is enabled and a security password is set, you
must log in to privileged console mode before using most of these commands.
See Chapter 2 for information on the console security feature.
The following sections describe all the console commands, give the command
format, and describe the significance of each parameter. The VAX Software
Handbook contains a detailed description of each command and its parameters
and qualifiers.

3.1 BOOT
The BOOT command initializes the processor and executes the VMB (virtual
memory block) program. The VMB program tries to boot the operating system
from the specified device or list of devices, or from the default boot device if
none is specified. The console qualifies the bootstrap operation by passing a
boot flags bitmap to the VMB program in R5.
Format:
BOOT [qualifier-list] [{boot_device},{boot_device},...]
If you do not enter either the qualifier or the device name, the default value is
used. Explicitly stating the boot flags or the boot device overrides, but does not
permanently change, the corresponding default value.
When specifying a list of boot devices (up to 32 characters, with devices
separated by commas and no spaces), the system checks the devices in the
order specified and boots from the first one that contains bootable software.

Console Commands 3–1

Note
If you include the Ethernet device, EZA0, in a string of boot devices,
it must be placed only as the last device of the string. The system
continuously tries to boot from EZA0.

Set the default boot device and boot flags using the SET BOOT and SET
BFLAG commands. If you do not set a default boot device, the processor times
out after 30 seconds and continuously tries to boot from the Ethernet device,
EZA0. To disable the autoboot feature, use three periods in place of the device
name for the SET BOOT command (SET BOOT . . . ).
Qualifiers:
Command specific:
/R5:{boot_flags}

A 32-bit hexadecimal value passed to the VMB program in R5.
The console does not interpret this value. Use the SET BFLAG
command to specify a default boot flags longword. Use the SHOW
BFLAG command to display the longword.

/{boot_flags}

Same as /R5:{boot_flags}

[device_name]

A character string of up to 17 characters. Longer strings cause
a VAL TOO BIG error message. When specifying a list of boot
devices, separate the device names using commas. Do not use
spaces. The console checks the length of the device name, but
does not interpret or validate it. The console converts the string
to uppercase, then passes the VMB program a string containing
the device name in R0. Use the SET BOOT command to specify
a default boot device or list of devices. Use the SHOW BOOT
command to display the default boot device. The factory default
device is the Ethernet device, EZA0. Table 2–1 lists the boot
devices supported by the Model 90 system.

Examples:
>>>SHOW BOOT
DKA300
>>>SHOW BFLAG
00000000
>>>B
!Boot using default boot flags and device.
(BOOT/R5:0 DKA300)
2..
-DKA300

3–2 Console Commands

3.2 CONTINUE
The CONTINUE command causes the processor to begin instruction execution
at the address currently contained in the program counter (PC). This address
is the address stored in the PC when the system enters console mode or the
address that the user specifies using the DEPOSIT command. The CONTINUE
command does not perform a processor initialization.
Format:
CONTINUE
Example:
>>>CONTINUE
$

!OpenVMS DCL prompt

3.3 DEPOSIT
The DEPOSIT command deposits data into the address specified. If you do not
specify an address space or data size qualifier, the console uses the last address
space and data size used in a DEPOSIT, EXAMINE, MOVE, or SEARCH
command. After processor initialization, the default address space is physical
memory, the default data size is longword, and the default address is zero.
If you specify conflicting address space or data sizes, the console ignores the
command and issues an error message.
Format:
DEPOSIT [qualifier-list] {address} {data} [data...]
Qualifiers:
Data control: /B, /W, /L, /Q, /N:{count}, /STEP:{size}, /WRONG
Address space control: /G, /I, /M, /P, /V, /U
Arguments:
{address}

A longword address that specifies the first location into which data is
deposited. The address can be an actual address or a symbolic address.

{data}

The data to be deposited. If the specified data is larger than the deposit
data size, the firmware ignores the command and issues an error response.
If the specified data is smaller than the deposit data size, the data is
extended on the left with zeros.

[{data}]

Additional data to be deposited (as many as can fit on the command line).

Console Commands 3–3

Examples:
>>>D/P/B/N:1FF 0 0

! Clear first 512 bytes of
! physical memory.

>>>D/V/L/N:3 1234 5

! Deposit 5 into four longwords
! starting at virtual memory address
! 1234.

>>>D/N:8 R0 FFFFFFFF

! Loads GPRs R0 through R8 with -1.

>>>D/L/P/N:10/ST:200 0 8

! Deposit 8 in the first longword of
! the first 17 pages in physical
! memory.

>>>D/N:200 - 0

! Starting at previous address, clear
! 513 longwords or 2052 bytes.

3.4 EXAMINE
The EXAMINE command examines the contents of the memory location or
register specified by the address. If no address is specified, + is assumed.
The display line consists of a single character address specifier, the physical
address to be examined, and the examined data.
EXAMINE uses the same qualifiers as DEPOSIT. However, the /WRONG
qualifier causes EXAMINE to ignore ECC errors when reading from physical
memory. The EXAMINE command also supports an /INSTRUCTION qualifier
that disassembles the instructions at the current address.
Format:
EXAMINE [qualifier-list] [address]
Qualifiers:
Data control: /B, /W, /L, /Q, /N:{count}, /STEP:{size}, /WRONG
Address space control: /G, /I, /M, /P, /V, /U
Command specific:
/INSTRUCTION

Disassembles and displays the VAX MACRO–32 instruction at the
specified address.

Arguments:
[{address}]

3–4 Console Commands

A longword address that specifies the first location to be examined.
The address can be an actual or a symbolic address. If no address is
specified, + is assumed.

Examples:
>>>EX PC

3.5 FIND
The FIND command searches main memory, starting at address zero for a
page-aligned 128K-byte segment of good memory, or a restart parameter block
(RPB). If the command finds the segment or RPB, its address plus 512 is left
in SP (R14). If it does not find the segment or RPB, the console issues an error
message and preserves the contents of SP. If you do not specify a qualifier,
/RPB is assumed.
Format:
FIND [qualifier-list]
Console Commands 3–5

Qualifiers:
Command specific:
Searches memory for a page-aligned block of good memory, 128K bytes
/MEMORY in length. The search checks only memory that is deemed usable by the
bitmap. This command leaves the contents of memory unchanged.
/RPB

Searches all physical memory for an RPB. The search does not use the
bitmap to qualify which pages are checked. The command leaves the
contents of memory unchanged.

Examples:
>>>EX SP
G 0000000E 00000000
>>>FIND /MEM
>>>EX SP
G 0000000E 00000200
>>>FIND /RPB
?2C FND ERR 00C00004
>>>

! Check the SP.
! Look for a valid 128 Kbytes.
! Note where it was found.
! Check for valid RPB.
! None to be found here.

3.6 HALT
The HALT command has no effect. It is included for compatibility with other
VAX consoles.
Format:
HALT
Example:
>>>HALT
>>>

! Pretend to halt.

3.7 HELP

3.9 LOGIN
Allows you to put the system in privileged console mode. When the console
security feature is enabled (see Section 2.2) and when you put the system
in console mode, the system operates in unprivileged console mode. You can
access only a subset of the console commands. To access the full range of
console commands, you must enter this command. The format of this command
is as follows:
LO[GIN]
When you enter the command, the system prompts you for a password as
follows:
Password:
You must enter the current console security password. If you do not enter the
correct password, the system displays the error message, ILL PSWD. When
you enter the console security password, the system operates in privileged
console mode. In this mode, you can use all the console commands. The system
exits from privileged console mode when you enter one of the following console
commands:
•

BOOT

•

CONTINUE

•

HALT

•

START

3.10 MOVE
The MOVE command copies the block of memory starting at the source address
to a block beginning at the destination address. Typically, this command has
an /N qualifier so that blocks of data are transferred. The destination correctly
reflects the contents of the source, regardless of the overlap between the source
and the data.

Console Commands 3–9

The MOVE command performs byte, word, longword, and quadword reads and
writes to moving the data efficiently. The MOVE command supports physical
and virtual address spaces only.
Format:
MOVE [qualifier-list] {src_address} {dest_address}
Qualifiers:
Data control: /B, /W, /L, /Q, /N:{count}, /STEP:{size}, /WRONG
Address space control: /V, /U, /P
Arguments:
{src_address}

A longword address that specifies the first location of the source data
to be copied.

{dest_address}

A longword address that specifies the destination of the first byte
of data. These addresses may be an actual address or a symbolic
address. If no address is specified, + is assumed.

Examples:
>>>EX/N:4 0
P 00000000 00000000
P 00000004 00000000
P 00000008 00000000

3–10 Console Commands

3.11 NEXT
The NEXT command executes the specified number of macro instructions. If no
count is specified, 1 is assumed. After the last macro instruction is executed,
the console reenters console I/O mode.
Format:
NEXT {count}
The console implements the NEXT command using the trace trap enable and
trace pending bits in the PSL and the trace pending vector in the SCB.
The console enters the Spacebar Step Mode. In this mode, pressing the
spacebar initiates each single step, and a carriage return forces a return to the
console prompt. The following restrictions apply:
•

If memory management is enabled, the NEXT command works only if the
first page in SSC RAM is mapped in S0 (system) space.

•

Overhead associated with the NEXT command affects the execution time of
an instruction.

•

The NEXT command elevates the IPL to 31 for long periods of time
(milliseconds) while single-stepping over several commands.

•

Unpredictable results occur if the macro instruction being stepped over
modifies either the SCBB or the trace trap entry. This means that you
cannot use the NEXT command with other debuggers. You must validate
PR$_SCCB before using the NEXT command.

Arguments:
{count}

A value representing the number of macro instructions to execute.

3.13 SEARCH
The SEARCH command finds all the occurrences of a pattern and reports the
addresses where the pattern was found. If the /NOT qualifier is present, the
command reports all addresses in which the pattern did not match.
Format:
SEARCH [qualifier-list] {address} {pattern} [{mask}]
SEARCH accepts an optional mask that indicates bits to be ignored (don’t care
bits). For example, to ignore bit 0 in the comparison, specify a mask of 1. The
mask, if not present, defaults to 0.
A match occurs if (pattern and not mask) = (data and not mask),
where:
Pattern is the target data
Mask is the optional don’t care bitmask (which defaults to 0)
Data is the data at the current address

Console Commands 3–13

SEARCH reports the address under the following conditions:

3.16 START
The START command starts instruction execution at the address you specify.
If no address is given, the current PC is used. If memory mapping is enabled,
macro instructions are executed from virtual memory, and the address
is treated as a virtual address. The START command is equivalent to a
DEPOSIT to PC, followed by a CONTINUE. It does not perform a processor
initialization.

Console Commands 3–19

Format:
START [{address}]
Arguments:
[address]

The address at which to begin execution. This address is loaded into
the user’s PC.

Example:
>>>START 1000

3.17 TEST
The TEST command invokes a diagnostic test program specified by the test
number. If you enter a test number of 0 (zero), all tests that are allowed to
be executed from the console terminal are executed. The console accepts an
optional list of up to five additional hexadecimal arguments.
You can see a full listing of all the tests by running test 9E.
Format:
TEST [{test_number} [{test_arguments}]]
Arguments:
{test_number}

A two-digit hexadecimal number specifying the test to be
executed. Test 9E displays a full list of all the available tests
and their parameters.

{test_arguments}

Up to five additional test arguments. These arguments are
accepted, but the console cannot interpret them.

Example:
>>>TEST 0
70..69..68..67..66..65..64..63..62..61..60..59..58..57..56..55..
54..53..52..51..50..49..48..47..46..45..44..43..42..41..40..39..

3–20 Console Commands

3.18 UNJAM
The UNJAM command performs an I/O bus reset, by writing a 1 (one) to IPR
55 (decimal).
Format:
UNJAM
Example:
>>>UNJAM
>>>

3.19 X—Binary Load and Unload
The X command is for use by automatic systems communicating with the
console. The X command loads or unloads (that is, writes to memory or reads
from memory) the specified number of data bytes through the console serial
line (regardless of console type) starting at the specified address.
Format:
X {address} {count} CR {line_checksum} {data} {data_checksum}
Arguments:

Console Commands 3–21

{address}

The address to unload data from or load data to.

{count}

Indicates whether to load or unload data, and also indicates the
amount of data to load or unload.
If bit 31 of the count is clear, data is received by the console
and put into memory. If bit 31 is set, data is read from memory
and sent by the console. The remaining bits in the count are a
positive number indicating the number of bytes to load or unload.

The console accepts a load or unload command when it receives
the carriage return.

{line_checksum}

The line_checksum is the next byte the console receives. The
line_checksum is not echoed.
The line_checksum is verified by adding all the command
characters, including the checksum and separating space, into an
8-bit register initially set to zero. The line_checksum does not
include the terminating carriage return, rubouts, or characters
deleted by a rubout. If no errors occur, the result is zero.
If the line_checksum is correct, the console responds with the
input prompt and either sends data to the requester or prepares
to receive data.
If the line_checksum is in error, the console responds with an
error message. This prevents the operator from inadvertently
entering into a mode where the console accepts characters from
the keyboard as data and does not provide an escape mechanism.

{data}

If the command is a load (bit 31 of the count is clear), the console
responds with the input prompt (>>>), then accepts the specified
number of bytes of data to be put into memory and an additional
byte of received data_checksum. The data is verified by adding
all data characters and the checksum character into an 8-bit
register initially set to zero. If the final content of the register
is nonzero, the data or checksum is in error, and the console
responds with an error message.
If the command is a binary unload (bit 31 of the count is set), the
console responds with the input prompt (>>>), followed by the
specified number of bytes of binary data. As each byte is sent, it
is added to a checksum register initially set to zero. At the end
of the transmission, the two’s complement of the low byte of the
register is sent.

{data_checksum}

3–22 Console Commands

If the data_checksum is incorrect on a load, or if memory or
line errors occur during the transmission of data, the entire
transmission is completed, and the console issues an error
message. If an error occurs during loading, the contents of the
memory being loaded are unpredictable.

The console represses echo while it is receiving the data string and checksums.
The console terminates all flow control when it receives the carriage return at
the end of the command line to avoid treating flow control characters from the
terminal as valid command line checksums.

3.19.1 Controlling the Console Serial Line
You can control the console serial line during a binary unload using the control
keys (Ctrl/C, Ctrl/S, Ctrl/O, and so on). You cannot control the console serial
line during a binary load, because all received characters are valid binary data.
The console has the following timing requirements:
•

It must receive data being loaded with a binary load command at a rate of
at least 1 byte every 60 seconds.

•

It must receive the command checksum that precedes the data within 60
seconds of the carriage return that terminates the command line.

•

It must receive the data checksum within 60 seconds of the last data byte.

If any of these timing requirements are not met, then the console aborts the
transmission by issuing an error message and returning to the console prompt.
The entire command, including the checksum, can be sent to the console as a
single burst of characters at the specified character rate of the console serial
line. The console is able to receive at least 4K bytes of data in a single X
command.

3.20 ! (Comment)
The comment character (an exclamation point) is used to document command
sequences. It can be placed anywhere on the command line. All characters
following the comment character are ignored.
Format: !
Example:
>>>! The console ignores this line.
>>>

3 Where two adapter cables are shown, they are electrically identical. The only difference is the angle at which

the cable is projected off of the 50-way connector.

4 The total length of cable used must not exceed 27 feet.

A.2 Host Power Rating
You must ensure that the total power drawn by the approved module, the host,
and other auxiliary equipment drawing power from the host, is within the
rating of the host power supply.
Digital has designed all permutations of the host configuration to operate
within the limits of the host power rating. The module power rating is shown
in Table A–2.

A.3 Module Isolation
Except at the connector that plugs into the host, clearance and creepage
distances of Xmm and Ymm, as listed in Table A–3, must be maintained
between the approved module and other parts of the host, including expansion
cards. Clearance is the shortest distance in air between two points. Creepage
is the shortest distance along a continuous surface between those same two
points.

1 The distances shown in parentheses apply in an uncontrolled environment where heat, humidity,
and temperature may fluctuate.

Creepage distances apply when the module is installed in a controlled
environment. You can check creepage distances by measuring the distance
between adjacent parts.
If in doubt, seek the advice of a telecoms safety engineer. Failure to install the
module in accordance with these instructions will invalidate the approval.
