3Sun3 machines usually need little or no preparation before installing
4NetBSD, other than the usual, well advised precaution of BACKING UP
5ALL DATA on any attached storage devices.

7You will need to know the SCSI target ID of the drive on which you
8will install NetBSD.  Note that SunOS/sun3 uses confusing names for
9the SCSI devcies: target 1 is sd2, target 2 is sd4, etc.

11It might be a good time to run the diagnostics on your Sun3.  First,
12attach a terminal to the "ttya" serial port, then set the "Diag/Norm"
13switch to the Diagnostic position, and power-on the machine.  The
14Diag. switch setting forces console interaction to occur on ttya.
15
16The console location (ttya, ttyb, or keyboard/display) is controlled
17by address 0x1F in the EEPROM, which you can examine and change in
18the PROM monitor by entering "q1f" followed by a numeric value (or
19just a '.' if you don't want to change it).  Console values are:
20	00: default graphics display
21	10: tty a (9600-N-8-1)
22	11: tty b (1200-N-8-1)
23	20: Color option board on P4

25NetBSD will use the EEPROM setting to determine which device to
26use as the console, so you should make sure it is correct.
