Is the SATA drive being emulated as IDE by BIOS?  Or, is this SATA
drive being used as native SATA?  If you're using BIOS calls, would
that mean the SATA drive is being emulated as IDE?

E.g., I can boot SATA drive emulated as IDE into DOS, but I can't
access other SATA drives from DOS.  I have to load SATA drivers in DOS
to access other SATA drives.  The SATA boot drive is being emulated as
an IDE drive by BIOS, but other drives aren't.

Could there be a similar issue or related issue here?  E.g., for an IDE
boot maybe the BIOS exposes other devices it may be emulating?
