Strictly you don't ened a BIOS extension. IDE drives were designed ot be
compatible wit hthe Western Digital controller in the original PC/AT. If
you can modify the dirve geometry tabel [1] then it will work with the
drivers in the BIOS ROMs.
Up to a point perhaps. But don't expect to get every byte of a 330GB
IDE drive. It might work with small IDEs (bad idea; they seem to be
falling like flies) or a small CF card.
In any case, you're going to need a PATA controller. Best to get one
with support built-in.
You might also get away with just a DDO, if your OS will support that
(i.e. I'm not aware of any DDOs that work with the 286 version of Xenix).
