I'm trying to set up an IBM0064N1D. It's a wide SCSI 2gig. The NCR SCSI bios recognizes it but Fdisk won't. Jumpers give 15 address choices. The ones I've tried haven't made a difference including ID0. Drive is recognized with auto start on or off. Same with slave or master sync and terminator power. I think I've exhausted all the combination of jumper switches. Is it time to give up?
