Base System Description
This chapter describes the VAX 4000 Model 200 base system, including the
following:
•

Power-up self tests

•

Digital Storage Systems Interconnect (DSSI) architecture

•

Specifications for the KA660-AA/BA CPU and MS650-BA/BB memory

1.1 System Overview
The VAX 4000 Model 200 base system components are housed in two
different enclosures: the BA430 enclosure, which contains a 12-slot Qbus backplane, and the BA215 enclosure, which contains a 6-slot Q-bus
backplane.
Each base system contains the following:
•

A KA660–AA/BA (M7626–A/–B) central processing unit (CPU) module

•

From one to four MS650–Bx memory modules.

The base system modules are located in the following card slots:
•

MS650–Bx memory modules are installed in slots 2 through 5.

•

The KA660 CPU module is installed in slot 1.

The base system operates from the KA660 CPU firmware and the controls
on the CPU cover panel. 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.
Figure 1–1 is a block diagram of the VAX 4000 Model 200 system.

1.2 Firmware Overview
Two electrically programmable read-only memory (EPROM) chips on the
KA660 CPU module contain the firmware. This firmware consists of the
following three major programs, which perform the system power-up selftests 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. The standard VAX console functionality
is emulated whenever you execute a program in ROM.
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 fatal 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 cover panel. See your VAX 4000 Model 200 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 the VAX 4000 Model 200 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 CPU cover panel to
enable, the console program enters Console I/O mode after the powerup self-tests are completed successfully. The console program also enters
Console I/O mode in response to any external halt condition.
CAUTION: Do not press the Restart button while the console program is
in console mode. Doing so destroys the system state and prevents normal
operation.
Console I/O mode allows you to control the system by entering commands at
the console prompt >>>. You may enter these commands in either uppercase
or lowercase letters. Enter each command, then press Return .

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.

also <CR>

Return

Action

(rubout)

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>).
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 X 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.
Toggles insertion/overstrike mode for command line editing. By
default, the console powers up to overstrike mode.
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 .
Moves the cursor one position to the left.
Moves the cursor to the end of the line.
Moves the cursor one position to the right.
Recalls the previous commands.
Deletes the previously typed character. Same function as X
(rubout), above.
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 .
Resumes output to the console terminal. Not echoed.

Ctrl/U

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

1.4.2 Console I/O Mode Commands
Table 1–2 lists and describes the I/O mode commands. You can display the
list of commands by entering HELP at the console prompt (>>>).
For a complete explanation of how to use the commands, along with
information on qualifiers and arguments, refer to the KA660 CPU Technical
Manual (EK–KA660–TM).

1.5 Digital Storage Systems Interconnect (DSSI)
The KA660 CPU module contains an embedded DSSI chip on the module
which becomes a DSSI bus interface connector that is dedicated to the mass
storage devices in the VAX 4000 Model 200 system. (See Figure 1–1 for the
VAX 4000 Model 200 block diagram.)
The DSSI bus interface connects to a DSSI Integrated Storage Element
(ISE). An ISE is a 5.25-inch disk drive that has special mounting brackets
for simplified enclosure installation and upgrading.
Each DSSI bus has the following characteristics:
•

A 4-Mbytes-per-second bandwidth

•

Up to eight nodes (one interface and up to seven ISEs)

•

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 DSSI bus interface supports up to eight nodes. These eight nodes
include the DSSI interface and seven ISEs.
An ISE can maintain connections to more than one DSSI interface. In a
dual-host configuration in which multiple CPUs can be connected to the
DSSI bus interfaces. For example, two VAX 4000 Model 200 systems can
have access to each ISE over a shared DSSI bus.
For more information about using VAX 4000 Model 200 systems in a dualhost configuration, and the advantages of such configurations, see the VAX
4000 Model 200 Dual-Host Systems manual.
