This is something that I've wanted to know for a long time. Would the
helpful soul with this info please email it to me also?

I can be reached at: amark@cs.joensuu.fi

Thanx!

...or better yet post some info.  It seems that there is enough interest.

I've seen a few postings over the past few days requesting info on how to
program the PC's DMA and interrupt hardware.  A good book to check out (in
fact the only book I've found so far) is Lewis Eggebrecht's "Interfacing to
the IBM Personal Computer".  It is a SAMS book, ISBN 0-672-22722-3, costs
about $25.00.  Be sure to get the second edition as it covers the AT and
PS/2 lines as well as the XT.

Should anyone know of other sources, please post to this newsgroup.  I
believe that the info would be of general interest.

As an interesting sidenote, I believe that Eggebrecht is now head of
engineering at Commodore-Amiga.

Yes, the first edition was an extremely helpful book.  I wore the covers
off my copy when I had it at my last job.  I coudln't remember the title
of the thing or I would have told the original questioner about it.
"That beige/brown/yellow book with a pc on the front" just doesn't do
for a description... :)

There's a lot more in that book than just DMA, it covers about
everything to do with the hardware.  Recommended for anyone doing
anything beyond rudimentary i/o work with a PC.
