Two of them, actually.  A 4/330 can go to 40MB (16 on 2 cards, 8 on the
mainboard) with 1MB SIMMs.  4MB SIMMs can be used with a high enough OBP
version (3.0.1?).  4.1.1 is the latest.

That's 0,30,1, as the sun4 boot partition was the second partition on the
CD (at least in Solaris 2.4, I believe SunOS 4 was the same).

The numbers are x,y,z where:

x = scsi controller
y = SCSI ID * 8 + LUN
z = partition ID

In case anyone is curious.  All in hex, of course.
