I just installed a 4.5G IBM SCSI-UW disk on my first SCSI adapter, and booted off of it now. Then mounts the RAID array to store our files/data on instead of booting from it as the system disk. > I have the same problem with 4.2 a DAC960 on an old IBM dual processor server. > > I was thinking trying to boot off floppy, a la: > > 1.
