- The OD is not a SCSI device. I guess you could call it a
- "special case," but then too booting from en (thinwire) or tp
- (10BaseT) would similarly be a "special case."

- That depends on how old the cube is. The original cubes shipped with
- the internal drive set to SCSI UNIT=0 (assuming they had internal
- drives). Later ones (and all slabs) shipped with the internal
- drive set to SCSI UNIT=1. The default boot device is "sd0"--
- that's *not* synonymous with SCSI UNIT=0--it's simply the lowest
- unit-numbered thing on the SCSI bus that has "boot potential."
