You probably do need to use `fdisk /MBR:80`. 80h was the traditional IO
port for the first BIOS HDD. IIRC, 00h for Floppy A:, 01h for Floppy B:,
all non-removables (usually meaning HDD) start at 80h.
This may be different for a BIOS (some Dell, Compaq, HP BIOSes, IIRC) that
supports Zip 100/250/750, LS-135/270, Jaz 1GB/2GB Drives, Syquest SparQ
1GB, SyJet 1500. Castlewood Orb 2.2GB/5.7GB drives.
What does `fdisk /INFO:80 /TECH` and `fdisk /INFO:81 /TECH` return when
booting from the FDI-USB image?
