1 2Sun3 machines usually need little or no preparation before installing 3NetBSD, other than the usual, well advised precaution of BACKING UP 4ALL DATA on any attached storage devices. 5 6You will need to know the SCSI target ID of the drive on which you 7will install NetBSD. Note that SunOS/sun3 uses confusing names for 8the SCSI devcies: target 1 is sd2, target 2 is sd4, etc. 9 10It might be a good time to run the diagnostics on your Sun3. First, 11attach a terminal to the "ttya" serial port, then set the "Diag/Norm" 12switch to the Diagnostic position, and power-on the machine. The 13Diag. switch setting forces console interaction to occur on ttya. 14 15The console location (ttya, ttyb, or keyboard/display) is controlled 16by address 0x1F in the EEPROM, which you can examine and change in 17the PROM monitor by entering "q1f" followed by a numeric value (or 18just a '.' if you don't want to change it). Console values are: 19 00: default graphics display 20 10: tty a (9600-N-8-1) 21 11: tty b (1200-N-8-1) 22 20: Color option board on P4 23 24NetBSD will use the EEPROM setting to determine which device to 25use as the console, so you should make sure it is correct. 26
