I agree. Using the switches on the back of an external enclosure or trying to set an ID via software is no substitute for setting the jumpers manually. >> My experience has been that when the Mac tries to boot with SCSI drives with >> duplicate ID's, it just hangs - it won't go to the flashing question mark. > > There are a couple of other possibilities which come up.

I did a little SCSI before I met a Mac - I once designed a fully-populated triple-wide VME Eurocard SCSI controller for a Navy SONAR system with TTL and PAL components only to have a NCR single-chip solution released within days after getting the board working and sent off to production.
