Sun3 machines usually need little or no preparation before installing
|
1999-01-13 10:30:01 +03:00
|
|
|
NetBSD, other than the usual, well advised precaution of
|
|
|
|
|
.Em backing up all data
|
|
|
|
|
on any attached storage devices.

You will need to know the
|
|
|
|
|
.Tn SCSI
|
|
|
|
|
target ID of the drive on which you
|
|
|
|
|
will install

.(Note

SunOS/sun3 uses confusing names for
|
|
|
|
|
the
|
|
|
|
|
.Tn SCSI
|
|
|
|
|
devices: target 1 is sd2, target 2 is sd4, etc.

It might be a good time to run the diagnostics on your Sun3. First,
|
|
|
|
|
attach a terminal to the "ttya" serial port, then set the "Diag/Norm"
|
|
|
|
|
switch to the Diagnostic position, and power-on the machine. The
|
|
|
|
|
Diag. switch setting forces console interaction to occur on ttya.

The console location (ttya, ttyb, or keyboard/display) is controlled
|
|
|
|
|
by address 0x1F in the EEPROM, which you can examine and change in
|
|
|
|
|
the PROM monitor by entering "q1f" followed by a numeric value (or
|
|
|
|
|
just a '.' if you don't want to change it). Console values are:
|
1999-01-13 10:30:01 +03:00
|
|
|
.Dl 00: No default graphics display
|
|
|
|
|
.Dl 10: No tty a (9600-N-8-1)
|
|
|
|
|
.Dl 11: No tty b (1200-N-8-1)
|
|
|
|
|
.Dl 20: No Color option board on P4
|

NetBSD will use the EEPROM setting to determine which device to
|
|
|
|
|
use as the console, so you should make sure it is correct.
