If the motherboard switches (or CMOS in >= AT) are set for 2 drives,

If the switches are set for 4 drives, then you could still use DRIVER.SYS
and access the drives as F: and G:,
Or use DRIVPARM, with /F:2

NOTE: DRIVPARM is present in both MS-DOS and PC-DOS, but UNDOCUMENTED in
PC-DOS, and is incompatible with the real IBM BIOS, although it will work
with almost all aftermarket BIOS's.
