Pardon me if I seem rude, but if you have the book, please
read it.  Your questions are specifically answered there.
Sorry, I don't have page numbers; my book is at home.

For those of you who don't have the book [yet :-) ], the
answers are:
- Yes, hard disks are supported.
-   The controller chip must be the same NEC chip used in
    the IBM PC or AT (depends on which driver you use).  I
    *think* the part number is 745 or 765 or some such.
-   The source code for both drivers is on both the PC and
    the AT diskette sets.
