As Jonathan pointed out the CD-ROM needs to be set to 512 byte block or the
Sun cannot boot from it. I don't know about Sony but that Plextor will just
DTRT once you jumper the pins labeled 'block'. Also set the SCSI ID to 6. That
is the default device that OBP looks for as the CD-ROM when you type 'boot

Just to be clear. Any SCSI CD will work to read disks from. It is just for
-booting- that the box wants to see a 512 byte unit.

The IPX was my first Sun boxen. It holds a warm place in my soul.
