Base System Description
This chapter describes the base system, including the following.
•

Power-up self-tests

•

Digital Storage Systems Interconnect (DSSI) architecture

•

Specifications for the KA6nn–AA CPU, and the MS690–BA/–CA/–DA memory
modules

1.1 System Overview
All base system components are housed in a BA440 enclosure, which contains a
12-slot backplane, 7 Q–bus slots; 1 slot reserved for CPU, and 4 slots for memory.
Each base system contains the following.
•

A KA6nn–AA (L4005–nA to L4006–nA) CPU module, located in slot 5.

•

From one to four MS690–BA/–CA/–DA memory modules.

MS690–BA memory modules are not supported on Models 700A and 705A.
The system operates from the KA6nn CPU firmware, the controls on the console
module, and the System Control Panel (SCP). The firmware is described in
Section 1.2. Base system operation also integrates Digital Storage Systems
Interconnect (DSSI) technology, which is discussed in Section 1.5.

1–2 Base System Description

1.2 Firmware Overview
Four flash-eraseable programmable read-only memory (FEPROM) chips on
the KA6nn CPU module contain the firmware. This firmware consists of the
following three major programs, which perform the system power-up self-tests
and diagnostics.
•

A console program

•

A set of self-tests for the CPU and memory

•

A primary bootstrap program (VMB)

The console program receives control whenever the processor halts. In a processor
halt, processor control passes to the console program and instruction execution
continues.
Control passes to the firmware under any of the following conditions.
•

You turn on the system.

•

You press the Restart button.

•

You assert the Q22–bus BHALT signal by pressing the Halt button.

•

You enter a break when the Break Enable/Disable switch is set to enable.

•

A HALT instruction is executed.

•

A system error occurs.

Base System Description 1–3

1.3 Power-Up
At power-up, the console program determines the console device type and console
language, then runs the self-tests for the CPU and memory. You choose the
console language when you perform the set-up operations during your console
terminal installation procedure.
You determine the type of power-up mode by setting the Power-Up Mode switch
on the CPU console module. See your Operation manual for the following
power-up information.
•

Power-up procedures

•

Power-Up Mode and Break Enable/Disable switch settings

•

Examples of successful power-up sequences

•

Boot and autoboot procedures

See your Troubleshooting and Diagnostics manual for examples of problems you
may encounter during power-up.

1.4 Console I/O Mode Overview
If you set the Break Enable/Disable switch on the console module to enable,
the console program enters Console I/O mode after the power-up self-tests are
completed successfully. The console program also enters Console I/O mode in
response to any external halt condition.
Console I/O mode allows you to control the system by typing commands at the
console prompt (>>>). You may enter these commands in either uppercase or
lowercase letters. Enter each command, then press Return .

1–4 Base System Description

1.4.1 Control Characters in Console I/O Mode
Table 1–1 lists the keypad control characters that have special meaning in
Console I/O mode.
Table 1–1 Console I/O Mode Control Characters
Character

Action

Return also <CR>

The carriage return ends a command line. No action is taken on
a command until after it is terminated by a carriage return. A
null line terminated by a carriage return is treated as a valid,
null command. No action is taken, and the console prompts for
input. Carriage return is echoed as carriage return, line feed
<CR><LF>.

< x (rubout)

When you press < x (rubout), the console deletes the previously
typed character. The resulting display differs, depending on
whether the console is a video or a hardcopy terminal.

For hardcopy terminals, the console echoes a backslash (\ ) followed by the character
being deleted. If you press additional rubouts, the additional deleted characters are
echoed. If you type a non-rubout character, the console echoes another backslash, followed
by the character typed. The result is to echo the characters deleted, surrounding them
with backslashes. For example:
EXAMI;E< x (rubout)< x (rubout)NE <CR>
The console echoes: EXAMI;E\ E\ ;NE<CR>
The console sees the command line: EXAMINE<CR>
For video terminals, the previous character is erased and the cursor is restored to its
previous position.
The console does not delete characters past the beginning of a command line. If you press
more rubouts than there are characters on the line, the extra rubouts are ignored. A
rubout entered on a blank line is ignored.)
Ctrl/A or F14

Toggles insertion/overstrike mode for command line editing. By
default, the console powers up to overstrike mode.

Ctrl/C

Echoes ^C<CR> and aborts processing of a command. Has no
effect as part of a binary load data stream. Clears Ctrl/S and
re-enables output stopped by Ctrl/O .

Ctrl/D or

Moves the cursor one position to the left.
Moves the cursor to the end of the line.

Ctrl/E
Ctrl/F or

Moves the cursor one position to the right.

Ctrl/H ,
F12

< x (rubout), or

Recalls the previous commands.
Deletes the previously typed character. Same function as <x
(rubout), above.

Ctrl/O

Ignores transmissions to the console until you enter Ctrl/O .
Echoes ^O when disabling output, which is not echoed when it
re-enables output. Output is re-enabled if the console prints an
error message, or if it prompts for a command from the terminal.
Output is also enabled by entering Maintenance mode: press
Break or enter Ctrl/C .

Ctrl/Q

Resumes output to the console terminal. Not echoed.

Ctrl/R

Echoes <CR><LF>, followed by the current command line. Can
be used to improve the readability of a command line that has
been heavily edited.

Ctrl/S

Stops output to the console terminal until you enter Ctrl/Q . Not
echoed.

Ctrl/U

Echoes ^U<CR>. Entered, but otherwise ignored if typed on an
empty line.

The console accepts Console I/O mode commands up to 80-characters long. Longer
commands produce error messages. The character count does not include rubouts,
rubbed-out characters, or the <CR> at the end of the command.
Two or more consecutive spaces and tabs are treated as a single space. Leading
and trailing spaces and tabs are ignored. You can place command qualifiers after
the command keyword or after any symbol or number in the command.
All numbers (addresses, data, counts) are hexadecimal, but symbolic register
names contain decimal register numbers. The hexadecimal digits are 0 through
9, and A through F. You can use uppercase and lowercase letters in hexadecimal
numbers (A through F) and commands.
The following symbols are qualifier and argument conventions.
[ ] = an optional qualifier or argument
{} = a required qualifier or argument

1–6 Base System Description

1.4.2 Console I/O Mode Commands
Table 1–2 lists and describes the Console I/O mode commands. You can display
the list of commands by entering HELP at the console prompt (>>>).
Table 1–2 Console I/O Mode Commands
Command

Action

BOOT

Initializes the processor and transfers execution to the VMB.

CONFIGURE

Invokes an interactive mode that permits you to enter Q22–bus
device names, then generates a table of Q22–bus I/O page
device CSR addresses and interrupt vectors.

CONTINUE

Causes the processor to resume instruction execution at the
point where the halt occurred. Does not perform a processor
initialization.

DEPOSIT

Deposits data into the address you specify. 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.

EXAMINE

Examines the contents of the memory location or register of
the address you specify.

FIND

Searches main memory starting at address 0 (zero) for a
page-aligned 128-Kbyte segment of good memory, or a restart
parameter block (RPB).

HALT

The HALT command has no effect. It is included for
compatibility with other VAX consoles.

HELP

Displays the correct syntax for all console commands.

INITIALIZE

Performs a processor initialization.

Exit from the secure console by entering the password at the
prompt. The LOGIN command may only be executed while in
secure console mode.

MOVE

Copies the block of memory starting at the source address to a
block beginning at the destination address.

Executes the number of macro instructions you specify. If you
do not specify a number, 1 (one) is assumed.

REPEAT

Repeatedly displays and executes the command you specify.
Press Ctrl/C to stop the command. You can specify any valid
console command except the REPEAT command.
(continued on next page)

Base System Description 1–7

Table 1–2 (Cont.) Console I/O Mode Commands
Command

Action

Finds all occurrences of a pattern and reports the addresses
where the pattern was found. If you include the /NOT qualifier,
the command reports all addresses for which the pattern did
not match.

SET BFLAG

Sets the default R5 boot flags. The value must be a
hexadecimal number of up to eight digits.

SET BOOT

Sets the default boot device. The value must be a valid device
name.

SET CONTROLP

Sets Control-P as the console halt condition, instead of a
BREAK.

SET HALT

Sets the halt action you define. Acceptable values are the
keywords: default, restart, reboot, halt, restart_reboot, or a
number in the range 0 to 4 inclusive.

SET HOST

Connects to the DUP or MAINTENANCE driver on the node
or device you specify.

SET LANGUAGE

Sets the console language and keyboard type.

SET PSE

Once a password has been set, the state of the secure console
enable bit, PSE, will determine whether the secure console
mode will be entered when certain console commands are
executed. If PSE = 0 (disabled), the console will remain in
privileged mode even if a password has been set. If PSE = 1
(enabled), the console will enter into secure mode when the
following commands are executed:
BOOT (with any supplied parameters)
CONTINUE
HALT
START
Once in secure console mode, the only commands which may be
executed are BOOT (with no qualifiers) and LOGIN (in order
to enter the password and exit into priviliged mode). Since the
BOOT command will take no qualifiers in secure console mode,
it is advisable to SET BOOT and SET BFLAG prior to exiting
privileged mode.

SET PSWD

Set the password to be entered in order to exit from the secure
console to the privileged console. A 16-character password
must be typed at the "PSWD1:" prompt. The password must
be typed again for verification at the "PSWD2:" prompt.

virtual address. Equivalent to a DEPOSIT to PC, followed by
a CONTINUE. Does not perform a processor initialization.

TEST

Invokes a diagnostic test program specified by the test number
you enter. If you enter a test number of 0 (zero), all tests
allowed to be executed from the console terminal are executed.
The console accepts an optional list of up to five additional
hexadecimal arguments.

UNJAM

Performs an I/O bus reset, by writing a 1 (one) to IPR 55
(decimal).

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. For use by automatic systems
communicating with the console.

The following examples show sample displays for the commonly used commands
SHOW and SET.
The SET command sets the parameter to the value you specify. The SHOW
command displays the console parameter you specify.

1.5 Digital Storage Systems Interconnect (DSSI)
The KA6nn CPU module contains two DSSI bus adapters and two more DSSI bus
adapters on an optional DSSI daughter board. The DSSI adapters are dedicated
to the mass storage devices in your system.
The DSSI adapters on the KA6nn CPU module provide a path to two separate
DSSI busses (Bus 0 and Bus 1) through which the CPU can communicate with
DSSI devices. The DSSI adapters on the optional DSSI daughter board provide a
path to two additional separate busses (Bus 2 and Bus 3) through which the CPU
can communicate with additional DSSI devices.
Each DSSI bus has the following characteristics.
•

A 4-Mbytes-per-second bandwidth

•

Up to eight nodes (one interface and up to seven additional DSSI Devices
(RF-series ISEs, TF85/TF86s, and adapters))

•

Eight data lines

•

One parity line

•

Eight control lines

DSSI architecture improves system performance as follows.
•

The DSSI bus handles all mass storage transactions.

•

Mass storage devices can act independently, since each device contains its
own controller. Several devices can work simultaneously.

The two DSSI bus interfaces support up to 16 nodes. These 16 nodes include the
2 DSSI interfaces and 14 additional DSSI devices.
An ISE can maintain connection to more than one DSSI interface. That feature
allows ISEs to be shared by multiple CPUs in a DSSI VAXcluster configuration.
The installation of KFDDB–AA/AF options offer 2 additional DSSI buses.
For more information about DSSI VAXcluster configurations and the advantages
of such configurations, see the section on DSSI VAXcluster capability in your
system Operation manual.
