Given that this is a 486, I don't think that the BIOS is your

What kind of IDE cable are you using to hook up the second drive? If
it's an 80-conductor (UDMA) cable, then it's likely that the old IDE
controller can't see the drive. You need the 40-conductor cable.
You may also have to jumper the drive to restrict it to 8GB or less
(some drives can do this).
FWIW,

The cable is a 40-pin ribbon cable (the old kind).
