However, SCSI Probe and everything else I have tried shows it as SCSI ID #4. Perhaps the jumpers are mislabelled, I don't know. >Your drive may need active termination.

The 68 pin to 50 pin adapter seems to also be a terminator. There are three IC chips on it, and it has jumpers on it labelled "Termination Disable". I have these jumpers all off. I suspected that I may have to try something like you suggested. I will play with the order of the drives, SCSI ID's, everything until I get it to work. An update on this: I had OS X installed on a partition of the 2 GB drive. As a goof, I booted into OS X to see what happened; both a cold boot and a warm reboot. Amazingly, OS X mounted the drive no problem on boot! But OS 9 still won't do it, unless I start up Drive Setup and mount it myself. However, I also tried (last night) to blow out all versions of MacOS and reinstall from scratch. OS 9.1 installed fine (but stlll won't mount the drive). I went to reinstall OS X with XPostFacto, and then POOF! The mac thought about it, then rebooted into OS 9 again. The OS X CD didn't even boot, let alone get me to the installer. >> Not sure if this will be any help. So take it for what it maybe worth---- I know OS X on my 7300/200 takes a lot more time to load than OS 9. That extra time my allow your Atlas to fully spin up and mount???. Thus, perhaps the Atlas is not spinning up fast enough for OS 9 to mount the volume on start up. Check any spin type jumpers on the Atlas. As far as the SCSI ID, how are your ID pins numbered, 1-2-3-4, or 0-1-2-3? You can have 16 different SCSI addresses (0 thru 15) on 68 pin drives and the jumper pins are additive. Usually the first pin is ID1 second pin is ID2, third pin is ID4. If you jump the first and second pin you get ID3, and so it goes until all four pins are jumped for ID15. Perhaps ID#2 on the adapter is third pin and thus SCSI ID4?? --glen (digest mode) -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
