[SunRescue] Booting a Sun3

[James W. Birdsall]

   You probably got this working a while ago (I'm running way behind on my
mail), but here's some thoughts:

   1) Sun-3's will not boot from a disk that has SCSI parity turned on.
   2) Sun-3's don't have the 3/0 SCSI ID inversion that SPARCs do. When you
tell a Sun-3 to boot from the disk with SCSI ID 0, it really does, instead of
remapping it to SCSI ID 3.
   3) I would think that dd'ing the miniroot onto the disk via another
machine would work, but I don't know enough about the mechanics of
bootblocks and such to be sure.
