Sun3 machines usually need little or no preparation before installing
|
|
NetBSD, other than the usual, well advised precaution of
|
|
.Em backing up all data
|
|
on any attached storage devices.
|
|
.Pp
|
|
You will need to know the SCSI target ID of the drive on which you
|
|
will install
|
|
.Nx .
|
|
.(Note
|
|
.Tn SunOS
|
|
on the \*M uses confusing names for
|
|
the SCSI devices: target 1 is
|
|
.Li sd2 ,
|
|
target 2 is
|
|
.Li sd4 ,
|
|
etc.
|
|
.Note)

It might be a good time to run the diagnostics on your Sun3. First,
|
|
attach a terminal to the
|
|
.Li ttya
|
|
serial port, then set the
|
|
.Dq "Diag/Norm"
|
|
switch to the Diagnostic position, and power-on the machine. The
|
|
Diag. switch setting forces console interaction to occur on ttya.
|
|
Note that the 3/80 has a
|
|
.Dq "software"
|
|
diag switch you can set at
|
|
the PROM monitor prompt. To turn on diag boot mode, do:
|
|
.Ic q 70b 12
|
|
To return to normal boot mode, do:
|
|
.Ic q 70b 6 .
|
|
.Pp
|
|
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
|
|
.Ic "q1f"
|
|
followed by a numeric value (or
|
|
just a
|
|
.Sq Li \&.
|
|
if you don't want to change it). Console values are:
|
|
.(tag 00xxx -offset indent
|
|
.It Li 00
|
|
Default graphics display
|
|
.It Li 10
|
|
tty a (9600-N-8-1)
|
|
.It Li 11
|
|
tty b (1200-N-8-1)
|
|
.It Li 20
