prep revision 1.2 
      1 Sun3 machines usually need little or no preparation before installing
      2 NetBSD, other than the usual, well advised precaution of BACKING UP
      3 ALL DATA on any attached storage devices.

      5 You will need to know the SCSI target ID of the drive on which you
      6 will install NetBSD.  Note that SunOS/sun3 uses confusing names for
      7 the SCSI devcies: target 1 is sd2, target 2 is sd4, etc.
      8 
      9 It might be a good time to run the diagnostics on your Sun3.  First,
     10 attach a terminal to the "ttya" serial port, then set the "Diag/Norm"
     11 switch to the Diagnostic position, and power-on the machine.  The
     12 Diag. switch setting forces console interaction to occur on ttya.
     13 
     14 The console location (ttya, ttyb, or keyboard/display) is controlled
     15 by address 0x1F in the EEPROM, which you can examine and change in
     16 the PROM monitor by entering "q1f" followed by a numeric value (or
     17 just 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
     22 
     23 NetBSD will use the EEPROM setting to determine which device to
     24 use as the console, so you should make sure it is correct.
