QEMU and DOS (Ultra)-DMA drivers (Emulation)

> May I ask why you are looking for such a driver?
Hmmm - replying to a question with a "why" question - isn't that a common phenomenon in forums where wanabee experts want to demonstrate a noobie that he/she has no idea what they are doing? :-D

Seriously: I have a feeling that Qemu is a bit buggy in this terrain. My attempts to make a DMA driver work in Qemu ( xdma32.dll ) were NOT successful so far. And this seems a bit strange, because adding support for multi-word DMA for an UDMA driver is a rather simple, almost trivial thing to do. I did it in 86Box and it worked, but admittedly, 86Box isn't exactly regarded as the gold standard in the emulator world.
