2.3 Console Security Feature
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:
•
LOGIN—Use this command with the security password to become a
privileged user.
•
BOOT—Use this command without parameters to boot the operating
system when the boot device has been set.
The following subsections describe how to do the following tasks:
•
Set the security password
•
Enable the console security feature
•
Log in to privileged console mode
•
Change the security password
•
Disable the security password
•
Exit from privileged console mode
Chapter 3 describes the console commands.
Console Security Feature and System Defaults 2–5
2.3.1 Setting the Security Password
The console security feature is disabled when you receive the system. To set
the security password on the system, follow these steps:
1. Enter the following command at the console prompt (>>>):
>>> SET PSWD
The system responds with the following prompt:
>>> PSWD1 :
Note
The security password must be a string of EXACTLY 16 hexadecimal
characters (0 through 9 and A through F).
Write down the security password and store it in a safe place. If
you forget the security password, you must call your Digital Services
representative to disable the console security feature.
2. Enter the security password and press Return.
The system does not display the security password as you type it. The
system responds with the following prompt:
>>> PSWD2 :
3. Verify the security password by entering it a second time.
Again the system does not display the security password as you type it. If
you 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:
?80 ILLEGAL PASSWORD
>>>
4. Repeat steps 1 to 3 if you see this error message.

2.3.2 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:
>>> SET PSE 1
2.3.3 Logging in to Privileged Console Mode
When the console security feature is enabled, you must enter the security
password to log in to privileged console mode. In privileged console mode you
can use the full range of console commands. To log in to privileged console
mode, follow these steps:
Note
You must set the security password before following these steps (see
Section 2.3.1).
1. Enter the following command:
>>> LOGIN
The system responds with the following prompt:
>>> Password:
2. Enter the security password and press Return.
The system does not display the security password as you type it. If you
enter the correct security password, the system returns you to the console
prompt and you become a privileged user. You can now use the full range
of console commands.
If you enter an incorrect security password, the system responds with the
following error message:
?81 INCORRECT PASSWORD
>>>
3. Repeat steps 1 and 2 if an error message displays.
Console Security Feature and System Defaults 2–7
2.3.4 Changing the Security Password
You must be a privileged user to change the security password. To change the
security password, follow these steps:
1. Follow the procedure in Section 2.3.3 using the current security password
to log in to the system.
2. Enter the following command:
>>> SET PSWD
The system responds with the following prompt:
PSWD1 :
3. Enter a new security password and press Return.
The system does not display the security password as you type it. The
system then responds with the following prompt:
PSWD2 :
4. Verify the new security password by entering it a second time.
The system does not display the security password as you type it. If
you enter the correct, current security password at the >>> prompt, and
correctly enter the new security password a second time, the system saves
the new security password in nonvolatile memory. The system does not
lose the new security password when you turn off the system.
If you incorrectly enter the new security password a second time, the
system responds with the following error message:

2.4 Setting the Default Boot Device
When the system is shipped, it is set to boot from the system disk, DIAO. This
RF-series disk holds the factory installed software (FIS).
If the TOY battery has discharged, the default boot device may have to be set.
Use SHOW BOOT to verify.
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 VMS device names.

Console Commands
This chapter describes the console commands that a priveleged user 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 Section 2.1 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 Section 2.3 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.
3.1 BOOT
The BOOT command initializes the processor and transfers execution to VMB.
VMB attempts 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 flag’s bitmap to VMB 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 flag 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 included in a string of boot devices, the Ethernet device, EZA0,
should be placed only as the last device of the string. The system will
continuously attempt to boot from EZA0.
Set the default boot device and boot flags with the SET BOOT and SET
BFLAG commands. If you do not set a default boot device, the processor times
out after 30 seconds and attempts to boot from the Ethernet device, EZA0.
Qualifiers:
Command specific:
/R5:{boot_flags}
A 32-bit hex value passed to VMB in R5. The console does not
interpret this value. Use the SET BFLAG command to specify a
default boot flag’s 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 32 characters. When specifying a list
of boot devices, the device names should be separated by commas
and no spaces. Apart from checking the length, the console does
not interpret or validate the device name. The console converts
the string to uppercase, then passes VMB a string descriptor to
this 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 100A 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 entered console mode
or an address that the user specifies using the DEPOSIT command. The
CONTINUE command does not perform a processor initialization. The console
enters program I/O mode.
Format:
CONTINUE
Example:
>>>CONTINUE
$
!VMS 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 and the default data size is longword. 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, it is extended on
the left with zeros.
Console Commands 3–3
[{data}]
Additional data to be deposited (as many as can fit on the command line).
Examples:
>>>D/P/B/N:1FF 0 0
! Clear first 512 bytes of
! physical memory.
>>>D/V/L/N:3 1234 5
!
!
!
!
>>>D/N:8 R0 FFFFFFFF
Deposit 5 into four longwords
starting at virtual memory address
1234.
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 on reads from physical
memory. The EXAMINE command also supports an /INSTRUCTION qualifier,
which will disassemble 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

Console Commands 3–5
3.5 FIND
The FIND command searches main memory, starting at address zero for a
page-aligned 128-KByte 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]
Qualifiers:
Command specific:
/MEMORY
Searches memory for a page-aligned block of good memory, 128 KBytes
in length. The search looks only at 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 looked at. The command leaves the
contents of memory unchanged.
Examples:
>>>EX SP
G 0000000E 00000000
>>>FIND /MEM
>>>EX SP
G 0000000E 00000200
>>>FIND /RPB

! 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:

3.9 LOGIN
Allows you to put the system in privileged console mode. When the console
security feature is enabled 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
use this command. This command may only be executed in secure console
mode. 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, INCORRECT
PASSWORD. 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 Console Commands
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 more than one datum is transferred. The destination
correctly reflects the contents of the source, regardless of the overlap between
the source and the data.
The MOVE command actually performs byte, word, longword, and quadword
reads and writes as needed in the process of moving the data. Moves are
supported only for the physical and virtual address spaces.
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

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, subsequent
spacebar strokes initiate single steps 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 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 in conjunction with other debuggers.

3–14 Console Commands
3.13 SEARCH
The SEARCH command finds all 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
SEARCH reports the address under the following conditions:
/NOT Qualifier
Match Condition
Action
Absent
True
Report address
Absent
False
No report
Present
True

False
Report address
The address is advanced by the size of the pattern (byte, word, longword, or
quadword), unless overridden by the /STEP qualifier.
Qualifiers:
Data control: /B, /W, /L, /Q, /N:{count}, /STEP:{size}, /WRONG
Address space control: /P, /V, /U
Command specific:
/NOT
Inverts the sense of the match.
Console Commands 3–15
Arguments:
{start_
address}
A longword address that specifies the first location subject to the
search. This address can be an actual address or a symbolic address. If
no address is specified, + is assumed.
{pattern}
The target data.
[{mask}]
A mask of the bits desired in the comparison.
Examples:
>>>DEP /P/L/N:1000 0 0
! Clear some memory.
>>>
>>>DEP 300 12345678
! Deposit some search data.
>>>DEP 401 12345678

3.14 SET
The SET command sets the parameter to the value you specify.
Format:
SET {parameter} {value}
Parameters:
BFLAG
Sets the default R5 boot flags. The value must be a hex number
of up to eight digits.
BOOT
Sets the default boot device. The value must be a valid device
name or list of device names as specified in the BOOT command
description in Section 3.1.
HALT
Sets the user-defined halt action. Acceptable values are the
keywords "default", "restart", "reboot", "halt", "restart_reboot", or
a number in the range 0 to 4 inclusive.
HOST
Makes a DUP connection to a DSSI device.
LANGUAGE
Sets console language and keyboard type. If the current console
terminal does not support the multinational character set (MCS),
then this command has no effect and the console message
appears in English. Values are 1 through 15.
PSWD
Allows you to enable or disable the console security feature of the
system. The SET PSE command accepts the following values:
1. 0—Console security disabled
2. 1—Console security enabled
When the console security feature is enabled, only a subset of the
console commands are available to the user. These commands
are listed in Section 2.3. To enable the complete set of console
commands once the console security feature is enabled, you must
use the LOGIN command (see Section 3.9).
PSWD
Allows you to set or change the console security password.
RECALL
Sets command recall state to either ENABLED (1) or DISABLED
(0).
SCSI_ID
Sets the SCSI ID of the SCSI controller, to a number in the range
0 to 7. The SCSI ID of the SCSI controller is set to 6 by default.

Format:
SHOW {parameter}
Parameters:
BFLAG
Displays the default R5 boot flags.
BOOT
Displays the default boot device.
CONFIG
Displays the system configuration. The command displays
information about the devices that the firmware has tested. It
also displays the device errors that the most recent device test
detected.
DEVICE
Displays all devices in the system.
HALT
Shows the user-defined halt action.
DSSI
Shows the status of all nodes that are on the DSSI bus. For each
node on the DSSI bus, the console displays the node number,
the node name, and the boot name and type of the device, if
available. The command does not indicate the "bootability" of the
device.
The node that issues the command reports a node name of "*".
The device information is obtained from the media type field of
the MSCP command GET UNIT STATUS. In the case where the
node is not running or is not capable of running an MSCP server,
then no device information is displayed.
ETHERNET
3–18 Console Commands
Displays hardware Ethernet address for all Ethernet adapters
that can be found. Displays as blank if no Ethernet adapter is
present.
LANGUAGE
Displays console language and keyboard type. Refer to the
corresponding SET LANGUAGE command for the meaning.
MEMORY
Displays main memory configuration.
MEMORY/FULL
Additionally, displays the normally inaccessible areas of memory,
such as the PFN bitmap pages, the console scratch memory
pages, the Q22–bus scatter-gather map pages. Also reports the
addresses of bad pages, as defined by the bitmap.
PSE
Displays the condition of the console security feature of the
system.
QBUS
Displays all Q22–bus I/O addresses that respond to an aligned
word read, and speculative device name information. For each
address, the console displays the address in the VAX I/O space in
hex, the address as it would appear in the Q22–bus I/O space in
octal, and the word data that was read in hex.
This command may take several minutes to complete. Press
CTRL/C to terminate the command. During execution, the
command disables the scatter-gather map.
RECALL
Shows the current state of command recall, either ENABLED or
DISABLED.
RLV12

Displays the status of all disks and tapes that can be found on
the Q22–bus that support the UQSSP protocol. For each such
disk or tape on the Q22–bus, the firmware displays the controller
number, the controller CSR address, and the boot name and type
of each device connected to the controller. The command does not
indicate whether the device contains a bootable image.
This information is obtained from the media type field of the
MSCP command GET UNIT STATUS. The console does not
display device information if a node is not running (or cannot
run) an MSCP server.
SCSI
Shows any SCSI devices in the system.
TRANSLATION
Shows any virtual addresses that map to the specified physical
address. The firmware uses the current values of page table base
and length registers to perform its search; it is assumed that

Console Commands 3–25
3.18 UNJAM
The UNJAM command performs an I/O bus reset, by writing a 1 (one) to IPR
55 (decimal). SHAC and SGEC are explicitly reset, EDAL_INTREQ register
error bits are cleared and SCST_DMA map registers are cleared.
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}
If bit 31 of the count is clear, data is received by the console and deposited 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 the command upon receiving the carriage return. The next
byte the console receives is the command checksum, which is not echoed. The
command checksum is verified by adding all command characters, including
the checksum and separating space (but not including the terminating carriage
return, rubouts, or characters deleted by rubout), into an 8-bit register initially
set to zero. If no errors occur, the result is zero. If the command checksum
is correct, the console responds with the input prompt and either sends
data to the requester or prepares to receive data. If the command checksum
is in error, the console responds with an error message. The intent is to
prevent inadvertent operator entry into a mode where the console is accepting
characters from the keyboard as data, with no escape mechanism possible.
3–26 Console Commands
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
for depositing to 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 are 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.
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, then 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 in order to avoid treating flow control characters
from the terminal as valid command line checksums.
You can control the console serial line during a binary unload using control
characters ( CTRL/C , CTRL/S , CTRL/O , and so on). You cannot control the
console serial line during a binary load, since 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 one 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 4 KBytes of data in a single X
command.
Console Commands 3–27
3.20 ! (Comment)
The comment character (an exclamation point) is used to document command
sequences. It can appear anywhere on the command line. All characters
following the comment character are ignored.
Format: !
Example:
>>>! The console ignores this line.
