Hello everybody out there,

I have a question regarding DMA programming: As far as I know, the
DMA has to be programmed with segments and offsets, which are not
available (?) in djgpp mode. Is it at all possible to program the
DMA from a djgpp compiled program?

If so, and if it is possible to point it out in a few lines, could
anyone do so?

My problem is that I have to record data via a soundblaster card, and
that is only possible with either interrupts (so I'm eagerly awaiting
release 1.11) or by polling the DMA. The direct bytewise mode is not
applicable to my problem :-(

Thanks in advance,

	Oliver
