installing yes, but all DMA based functions will not work. To get DMA
working the driver needs to program the virtual DMA engine of the Magnum
and handle cache flushes. This isn't needed for Intel, so the ISA
sounddriver don't do this.

I've never looked at the ISA sound support. I had a quick look over
the spec of the Magnum sound board (I hope, that's the same one, which
is built in on my M700 mainboard) and pulled together all the needed
datasheets. But there is still more important stuff to do, than sound.

I haven't look at my processor. Maybe next time when I open my box.


See, you not only have to be a good coder to create a system like Linux,
you have to be a sneaky bastard too ;-)
