So I've been looking at the popular asrock 775i65G R3.0 board for a win98/dos machine but have read conflicting things about how a pci sound card would work. I have a Yamaha YMF 744 card that was supposed to be good for DOS but I read here: Yamaha YMF7x4 Guide that the board I have does not support DDMA and therefore the card won't work under DOS.
But then I saw a video by philscomputerlab that states the i865 chipset is great for dos/win98 and apparently works fine with at least the aureal vortex 2: https://youtu.be/rr2r_mvKfuQ. But unfortunately aureal vortex 2 cards aren't exactly cheap.
So since the asrock board uses the 865G chipset I'm not sure if it would be good or not?
I also have a socket 939 board that has a vt8251 southbridge which I've read doesn't support DDMA either. However, supposedly the vt8237 does support DDMA.
So what exactly do I need to make sure a sound card works in DOS with the more modern 939/775 chipsets?
