[net.wanted.sources] Intel 8237-A5 DMA Programming, Anyone?

mlandau@Diamond.BBN.COM (Matt Landau) (09/09/86)

Does anyone in Usenet-land have experience programming the Intel 8237-A5 DMA
controller used in the IBM PC, preferably from Microsoft assembly language?
I've got the Intel data sheets, but they're not as much help as they might
be (surprise :-).  The task at hand is to communicate with a peripheral
device (someone else's) that's sending data via DMA, and to retrieve that
data into memory buffers somewhere in a Lattice C program.

Ideally, someone's already written a library of DMA communication routines
that s/he wouldn't mind sharing with the Net.  Failing that, I'll settle for
pointers and advice.

Please respond by mail, and if anyone else is interested, I'll post a
summary.  Thanks as always.
