Get a copy of the MS-DOS "Encyclopedia".  I know that's a pretty stupid
name for a $75 paperback, but there is some previously undocumented
information there that is still no printed in the MS-DOS technical
reference manual.  None of this stuff is new; the only reason MS finally
put it in print is that it became common knowledge in the industry
anyway.

Don't get a copy of Michael Hyman's book "Memory Resident Utilities,
Interrupts, and Disk Management with MS & PC DOS" MIS Press.  It's
too vague where the details are important, and the bottom line is
wasted time & money.  Not Recommended.

Also, there is a list of (previously) undocumented DOS functions
posted on SIMTEL.  I don't know the name of it right off-hand.

Lastly, a good book on multithreaded operating systems should be handy.
You need to have a good understanding of the issues involved in reentrancy,
interrupt service routines, and timeslicing.

Good Luck.
