    You normally have to remove the drive and there is a dip switch to set scsi id.

    You first need to check what other units / devises you have on that chain. We use to use SCSIprobe. We also used unit #7 for our cpu. No more than one unit can have to same number. If all you have is the hard drive and a CD (which is usually #3), then you either have a bad hard drive, SCSI chain, SCSI ribbon cable, system disk or a system that isn't able to load on the 9600. The 9600 should have 2 SCSI chains, so moving to the other SCSI chain is very easy.

    The main SCSI hard drive is id 0, but it shouldn't make a difference if there are no conflicts.



    Have you zapped the PRAM ? (Hold down command + option + p + r immediately after booting the Mac until the Mac resets). This can fix quite a few startup problems (e.g. my 6400 didn't like the Darwin 6 CD, and PRAM zapping was needed to bring it back).
