I have two books that I think might be useful to someone on the MESS team emulating PC hardware...

DOS and BIOS Functions Quick Reference
1989 QUE
ISBN 0-88022-426-6

IRQ, DMA, & I/O
1995 MIS:Press
ISBN 1-55828-456-7

Both free if you want them, just tell me where to send them.
If nobody claims them, they're going either to my local library or in the trash.
