Assuming that your problem is not related to SCSI configuration such as termination or ID selection, (and if you don't know what those mean, then ask, because that's likely your problem) then the simplest test is to just plug the SCSI cable into the other SCSI port. The S900 has two independent SCSI busses and you have a separate ribbon cable connector for each one inside the machine. So, if it doesn't work on one connector try the other connector. One connector is near the edge of the board close to the external SCSI port. This is the Bus 1 5 MB/s internal/external SCSI bus. The other is closer to the DIMM slots and is the Fast Internal SCSI Bus, Bus 0. It is unlikely that they'd both be bad in given machine. >Again, none of the CDs work so I can't move them in and out of a working >model to test. Someone told me it could be the motherboard itself. How on >earth can I check that? The only way it could be the motherboard on an otherwise working machine is if one of the SCSI ports was blown. But again, it's unlikely that they are both bad. And if you have working hard drives connected to either one, then it's fine. Jeff Walther -- SuperMacs is sponsored by <http://lowendmac.com/> and...
