Which simple i/o card? DMA is used by the floppy disk controllers,
sound cards, dram refresh, and little else! Perhaps you mean a network
card?

Sure!

OK, a pretty cool book on PC hardware is PC Intern (ISBN 1557552827),
but there's a lot of misprints. They're rather obvious, but in a few
places, numbers of ports etc. are printed wrong, and you have to
deduce a bit. Apart from that, it covers lots of chips (DMAC, PIC,
DSP, OPL2, CRTC, etc).

And you can always ask me questions, if you want; I've written a sound
blaster driver... but I still can't get 16 bit DMA working!!!
