If you can find a copy, pick up The Programmer's CP/M Handbook, by Andy
Johnson-Laird (Osborn/McGraw Hill, ISBN 0-88134-103-7).  It's an excellent
reference on the subject, having two chapters devoted to writing a BIOS with
a lot of programming examples.

In case you haven't heard, DR US was recently bought out by Novell, so I
suspect that they are in a pretty serious state of transition right now.
