A word of caution about the Phoenix book:  There are a significant number of
typos in the book (especially in the tables).  We used the Phoenix book to
*learn* ABIOS, but the IBM Tech Reference to *use* it.

On the subject, has anybody had any trouble with specific ABIOS functions?
We've found at least one bug (in the Reset Disk service) and have had some
poor luck with one other function (switch back to Real mode).
