I'm confused why FILO hasn't started using the OpenBIOS IDE driver if FILO's
driver is a mess.

I thought patches would be too hard to look through, since there are changes
on nearly every line to support segments.  All of the data structures had to
be moved into the EBDA (Extended BIOS Data Area) segment, and that meant
passing different parameters to every function.  Generating the patches is
easy, though, so I'll send you one on Monday.

Yep, that would be the next thing to do.

Is there another free BIOS somewhere that already has that support?  Maybe I
shouldn't be starting with ADLO at all.
