SCSI is great but there is a bit of vodoo to it.

If everything has been moved you need to a) check for conflicts b) check for termination. Termination is easy, kind of. Basic rule is the last device in the chain gets terminated. Device ID's are set in order of the chain, 1st device having the lowest number, usually.

It is possible to have some devices in a chain show up and not others even though the device works.

Terminated cables are easy to spot, they will have a big block on the end. Won't look like a normal ribbon cable.

Checking termination on drives is easy, look at or around the pinouts, the area on an IDE where you would set master/slave. The drive should have a schematic telling you what pins are what, sometimes it's printed right on the board. Termination is usually labled "term"

SCSI Id's range from 0-7. The ID is acheived by jumping 3 pinouts. No jumpers = 0, jumper first set only = 1, jumper second set only=2, jumper third set only= 4. Jumping combinations gets you 3,5,6,7. jumper 1st+2nd =3, 1st+3rd=5, 2nd+3rd=6, all 3=7.

CD drives like to be either 1st or last, not in between. Boot drives should be set to 0.

Now if everything is still in the original server and the boot drive does not show I'd say it's fuched.
I am using a more modern computer. I have no interest in working with a 486 server with 64 megs RAM . The computer I am using only has a IDE cdrom to boot my wonder cd and a SCSI card for the two drives. Same cable from server, but terminated after second drive with my terminator. The cable does not have an external one and nothing built in.
