After getting the disk installed we were unable to run FDISK to setup the DOS partition. It failed with "Error reading fixed disk." We ran the hardware diagnostics and it failed trying to access track 0 on the hard disk. My guess is that the BIOS in this old beast doesn't know what to think about the 20M drive (they were all 10M back then I believe) and improperly identifies it to DOS at which point it goes south. Can anyone confirm my hunch? I think I have two options available: 1) Find some newer BIOS ROMs and installed them in the PC or 2) Install the disk in a newer machine, run FDISK (and FORMAT?), then put it back in the old PC. I hate to go to such trouble if I'm on the wrong track... FWIW, the BIOS is version C1.10 dated 25-Apr-1981, the new disk is a Kalok KL320, the controller is Western Digital.
