2.2 Using the Alternative Console Port
MicroVAX 3100 systems provide an alternative console port through MMJ port
3. You can use this alternative console port in the same way as you would use
the standard console port, MMJ port 1. However, the alternative console port
does allow you to halt the system by pressing the break key on the keyboard,
a feature not available when you use the standard console port. To enable the
alternative console port, follow these steps:
1. Set the on/off switch on the system unit to the off (O) position.
2. Connect a terminal to MMJ port 3.
3. Set the break/enable switch to the up position.
The break enable LED lights when you set the switch to the up position.
4. Set the on/off switch on the system unit to the on ( | ) position.
The system recognizes the position of the switch only when you set the
power switch to the on ( | ) position.

2.3 Console Security Feature
The console security feature allows you to disable most of the system console
commands. When you set the security password, privileged users, who know
the security password, can use the full range of console commands. However,
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.

Chapter 3 describes the console commands.
The following subsections describe how to do the following:
•

Set the security password

•

Enable the console security feature

•

Change the security password

•

Disable the security password

•

Exit from privileged console mode

2–4 Console Security Feature and System Defaults

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 to 9 and A to 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 a 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.
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:
?31 ILL PSWD
>>>
4. Repeat steps 1 to 3 if you see an error message.

Console Security Feature and System Defaults 2–5

2.3.2 Enabling the Console Security Feature
When you have set the security password, you must enable the console security

Chapter 3 describes each of these commands.

2–8 Console Security Feature and System Defaults

2.4 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 VMS™ device names.

To set an alternative default boot device, enter the SET BOOT command using
the VMS 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 ESA0
The system responds with the following display when you have set ESA0 as
the default boot device:
BOOT = ESA0

Console Security Feature and System Defaults 2–9

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

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.

3.1 BOOT
Passes control to the virtual machine bootstrap (VMB) program, which resides
on the system ROM. The format of this command is as follows:
B[OOT] [/[R5:]<bflg>] <ddau>
where:
•

R5: represents a register, through which the hexadecimal value
represented by <bflg> is passed to the VMB.

•

<bflg> is the boot flag value.

•

<ddau> is the name of the boot device. It passes to the VMB in register
R0.
The Ethernet network boot device name is ESA0; SCSI boot device names
have the following format:
ddcull
where:
dd is the device mnemonic
c is the controller destination (always A)

Console Commands 3–1

u is the SCSI ID value of the boot device
ll is the logical unit number
The console program accepts device names in lowercase characters, but it
is recommended that you use uppercase characters. You can specify more
than one boot device, and you can type a colon at the end of the device
names as shown in the command format. You can specify up to two devices
on the command line. You must separate device names by typing either a
space or a comma.
If the nonvolatile RAM (NVR) contains a default boot device name, the console
program passes the descriptor for this device to the VMB. The VMB then boots
the system from the specified device.
If you do not specify a device name or qualifiers or both in the command, the
system attempts to boot from the default boot device specified in the NVR. If
the default boot device is not defined ({NULL}), the console program passes
a descriptor for device ESA0 to the VMB program. This triggers the VMB
program to boot the system over the network.

3.2 CONTINUE
Allows you to exit from console mode and enter (or reenter) program mode (the
operating system). The format of this command is as follows:
C[ONTINUE]
The address to which control passes is one of the following:
•

The address stored in the program counter when the system went into
console mode.

•

The address that the user specifies using the DEPOSIT command.

3.3 DEPOSIT
Transfers the specified data to the specified address. The format of this
command is as follows:
D[EPOSIT] [{/B | /W | /L | /Q | /A}] [{/P | /V | /I}] [/G] [/U] [/N:<n>]
[{<addr> | <sym> | + | - | * | @} [<datum>]]
where:
•

/B /W /L /Q /A /P /V /I /G /U /N:<n> are deposit command qualifiers
(see Table 3–1).

3–2 Console Commands

If you do not specify a size or address qualifier, the console program uses
the size and address qualifier of the previous memory-specific command. If
you specify conflicting qualifiers, the console program ignores the command
and generates an error message. The effects of the miscellaneous qualifiers
are not valid outside the command in which they are specified.
Note
The /U (unprotect) qualifier allows access to almost any address. If
you do not use the /U qualifier, you can access address locations in
the range 2000.0000 to 3FFF.FFFF (excluding the TOY clock). The /U
qualifier is intended for use only by firmware developers.

•

<addr> is the hexadecimal address into which you want to deposit the
data.

•

<sym> is a mnemonic that represents the address into which you want to
deposit data (see Table 3–2).

•

+ - * @ are operators that you can use for relative memory addressing (see
Table 3–3).

•

<datum> is the value you want to deposit in the address location you
specify.

Addressing Method Description

The memory address specified by the most recent DEPOSIT or
EXAMINE command.

The memory address immediately following the address specified by the
most recent DEPOSIT or EXAMINE command. For physical or virtual
memory address, the address specified is the address of the most recent
DEPOSIT or EXAMINE command plus the size that the most recently
specified size qualifier indicates (1 for byte, 2 for word, 4 for longword.)

The memory address immediately before the address specified by the
most recent DEPOSIT or EXAMINE command. For physical or virtual
memory address, the address specified is the address of the most recent
DEPOSIT or EXAMINE command minus the size that the most recently
specified size qualifier indicates (1 for byte, 2 for word, 4 for longword).

Indirect addressing. The format is @<address>, where <address> is a
hexadecimal address used as a pointer to another address. If you do not
specify an address, the address that the command uses is the address
used by the most recent memory referencing command.

Table 3–4 shows some examples of memory addressing.

Console Commands 3–5

Table 3–4 Examples of Memory Addressing
Example

Description

DEPOSIT R0 200

Stores the value 200 in the register R0.

DEPOSIT/P @R0 200

Stores the value 200 in the address pointed to by the
register R0. The /P qualifier specifies that the value in the
R0 register is a physical address reference.

DEPOSIT/V @R0 200

Stores the value 200 in the address pointed to by the
register R0. The /V qualifier specifies that the value in the
R0 register is a virtual address reference.

DEPOSIT @ 200

Stores the value 200 in the address specified by the most
recent memory referencing command.

3.4 EXAMINE
Displays, in hexadecimal format, the contents of the specified address. The
format of this command is as follows:
E[XAMINE] [{/B | /W | /L | /Q | /A}] [{/P | /V | /I}] [/G] [/U] [/N:<n>]
[{<addr> | <sym> | + | - | * | @} [<datum>]]
where:
•

/B /W /L /Q /A /P /V /I /G /U /N:<n> are qualifiers. The EXAMINE
command uses the same set of qualifiers as the DEPOSIT command (see
Table 3–1).

•

<addr> is the hexadecimal address into which you want to deposit the
data.

•

<sym> is a mnemonic that represents the address that you want to
examine. The EXAMINE command uses the same mnemonics as the
DEPOSIT command (see Table 3–2).

•

+ - * @ are operators that you can use for relative memory addressing. The
EXAMINE command uses the same operators for memory addressing as
the DEPOSIT command (see Table 3–3).

•

<datum> is the value you want to deposit in the address location you
specify.

3–6 Console Commands

3.5 FIND
Forces the console program to search the main RAM memory (starting at
physical address zero) for the following:
•

A page-aligned 128K-byte segment of main memory

•

A restart parameter block (RPB)

If the console program finds a 128K-byte memory segment or an RPB, the
console program places the starting address of the segment or RPB, plus
512, in the stack pointer (SP) register. If the console program does not find a
memory segment or RPB, the console program issues an error message. The
format of this command is as follows:
F[IND][/MEMORY | /RPB
where:
•

/MEMORY is a qualifier that specifies a search for a 128K-byte, pagealigned segment of memory.

•

/RPB is a qualifier that specifies a search for an RPB.

The FIND command searches for an RPB if you do not enter a qualifier.

Flag

Definition

00000001

RPB$V_CONV—Conversational boot. At various points in the
system boot procedure, the bootstrap code requests parameters and
other input from the console terminal. If the DIAG is also on, the
diagnostic supervisor then goes into MENU mode and prompts the
user for devices to test.

00000002

RPB$V_DEBUG—Debug. If this flag is set, VMS maps the code for
the XDELTA debugger into the system page tables of the operating
system.

00000004

RPB$V_INIBPT—Initial breakpoint. If RPB$V_DEBUG is set, VMS
executes a BPT instruction immediately after enabling mapping.

00000008

RPB$V_BBLOCK—This skips the files-11 boot and performs only
the boot block type boot.

00000010

RPB$V_DIAG—Diagnostic boot. The secondary bootstrap is an
image called [SYSMAINT]DIAGBOOT.EXE.

00000020

RPB$V_BOOBPT—Bootstrap breakpoint. Stops the primary and
secondary bootstraps with a breakpoint instruction before testing
the memory.

00000040

RPB$V_HEADER—Image header. Takes the transfer address of
the secondary bootstrap image from that file’s image header. If
RPB$V_HEADER is not set, transfers control to the first byte of the
secondary boot file.

00000080

RPB$V_NOTEST—Memory test inhibit. Sets a bit in the PFN bit
map for each page of memory present. Does not test the memory.

00000100

RPB$V_SOLICT—File name. Prompts for the name of a secondary
bootstrap file.

00000200

RPB$V_HALT—Halt before transfer. Executes a halt instruction
before transferring control to the secondary bootstrap.

00000400

RPB$V_NOPFND—No PFN deletion (not implemented); intended
to inform the VMB not to read a file from the boot device that
identifies bad or reserved memory pages, so that the VMB does not
mark these pages as valid in the PFN bitmap.

00000800

RPB$V_MPM—Specifies that multiport memory is to be used for the
total executive memory requirement. No local memory is to be used.
This is for tightly-coupled multiprocessing. If the DIAG is also on,
