IIRC the Aureal support was fairly poor. Just a
warning.
Any PCI card is probably not going to be able to support legacy DMA type
transfers, but siimple SB port 220H I/O shouldn't be a problem with PCI
cards that do emulation right. There have been some discussions about PCI
sound cards in real mode DOS on the vintage gaming fora.
Where is this board? I googled it but I am not sure if the hits I
received were "the one". :)
