1Sun3 machines usually need little or no preparation before installing
2NetBSD, other than the usual, well advised precaution of BACKING UP
3ALL DATA on any attached storage devices.

5You will need to know the SCSI target ID of the drive on which you
6will install NetBSD.  Note that SunOS/sun3 uses confusing names for
7the SCSI devcies: target 1 is sd2, target 2 is sd4, etc.

9It might be a good time to run the diagnostics on your Sun3.  First,
10attach a terminal to the "ttya" serial port, then set the "Diag/Norm"
11switch to the Diagnostic position, and power-on the machine.  The
12Diag. switch setting forces console interaction to occur on ttya.

14The console location (ttya, ttyb, or keyboard/display) is controlled
15by address 0x1F in the EEPROM, which you can examine and change in
16the PROM monitor by entering "q1f" followed by a numeric value (or
17just a '.' if you don't want to change it).  Console values are:
18	00: default graphics display
19	10: tty a (9600-N-8-1)
20	11: tty b (1200-N-8-1)
21	20: Color option board on P4

23NetBSD will use the EEPROM setting to determine which device to
24use as the console, so you should make sure it is correct.
