I had a right messabout getting sound for dos to work,
if i was you id buy a board with an ISA slot if you can find one (ebay !).
I have a ISA soundblaster 16 and sound blaster 2.0 and
both work perfect and sound nice.
It all comes down to motherboard, quite a few dont support pci soundblaster
devices. Asus p4c800 deluxe does, most pci soundcard works with this board for me but SIS chipsets - forget it

, and most new motherboards wont touch a dos pci soundcard.
