The IBM is a new acquisition and I removed all drives but the cdrom and the tape and it still didn't work. Could a jumper on the motherboard make a difference. I went through them to make sure they made sense. Perhaps I should again. I don't remember if I changed any or not. The bios are as you sent them. Standard but with write-through amd ISA gating disabled. I am rebuilding the boot floppy now and will try it tonight. If it fails, I will rebuild with the > > options "SCSI_NCR_MAX_SYNC=0" #Restrict NCR to asynch. transfers line removed and try that. Boyd Why the restriction? -- _______________________________________________________________________ Boyd Faulkner faulkner@isd.tandem.com _______________________________________________________________________
