command, and the monitor is identifying its configuration. Keyb is either VT100 or
Two-tone, depending which keyboard your monitor ROMs support.
Sun Workstation, Model Sun-2/120 or Sun-2/170, Sun-2 keyboard
The Model 120 or 170 workstation has just been powered on, or you entered a 'kb'
command, and the monitor is identifying its configuration.
Timeout Bus Error .. .
See "Bus Error ... ". The attempted access was invalid because no device responded at
the addressed location. This most often happens for Multibus references. The program
was probably trying to access a device or section of memory which does not exist, or
which has gotten into a hung state. If this occurs in response to a boot command, the
device you are trying to boot from is not installed in your system.
tm: error nn during config of ctlr cc
tm hard err nn
tm: no response from ctlr cc
A standalone program (possibly the boot program) is trying to use the Tapemaster
nine-track tape drive, and has encountered an error. This could be caused by a bad or
missing tape, loose or misplugged cables, incorrect jumpers on the Tapemaster con-
troller board, or hardware errors. Nn can be decoded by looking in the Tapemaster
Product Specification.
Unknown device
The current program (possibly the boot program) has tried to use a device which is
unknown to the standalone I/O system.
Upper Byte Parity Bus Error ...
See "Bus Error ... " and "Parity ... ". The preceding access was to a word in memory
with a parity error in its upper byte.
ui i, uoo, uaabaud, ubbbaud, uuaaaaaa, uecho
The monitor is describing its console and serial port configuration in response to a 'u'
command. I is the input device (k for keyboard, or a or b for a serial port);
0
is the
output device (a for screen, or a or b); abaud and bbaud are the baud rates on the serial
ports; aaaaaa is the address of the Zilog 8530 chip which implements the serial ports,
and echo is 'e' if input echoing is enabled ("full duplex") or 'ne' if disabled ("half
duplex").
Using RS232 A input.
A-12
The monitor did not find the Sun keyboard, so it is taking input from one of the serial
ports on the back of the Workstation, marked "RS232 A". If this is unexpected, make
sure that the keyboard is plugged into the correct socket on the workstation. The key-
board must be plugged in before system power is turned on. If you connect a Sun key-
board after this message appears, you can let the monitor know about the keyboard by
entering the Abort sequence (hold down the upper left key on the Sun keyboard, and
press 'A'). The monitor will switch to using the Sun keyboard since that's where the
Abort was typed. Then type 'c' to continue whatever program was running when you
aborted.
If
you don't want to use a Sun keyboard, connect a normal ASCII terminal to the
"RS232 A" connector on the back panel. Configure the terminal for 9600 baud, no
parity, one stop bit. Things that you type on the terminal will be displayed on the Sun
video screen, if you have one, or on the terminal's screen.
