All right. I undefined the disk in CMOS (which now believes there is no hard disk installed) but I'm having the same problem. FDISK hangs creating a new partition, just after it says "Drive capacity is 77 Mbytes" or the message to that effect. I checked out the jumpers on the unit, and they are set for IRQ 11, BIOS address C8000, I/O port 170, drive select 0.
