I'm trying to run an old DOS game, Papyrus's Indy Car Racing II, in a DOS full screen. The game runs fine, but I'm having trouble getting sound to work. The program lets you pick a sound card, but of course my Aopen PCI AWE320 (Crystal CS4614 chipset) is not listed. The other option is to specify the Port Address, IRQ & DMA channel. I know the IRQ, because the BIOS displays it upon boot up. Does anyone know a way to determine the Port Address & DMA? There's nothing in the documentation that came with the sound card. Aopen's website is useless and they have absolutely no customer support whatsoever. Any ideas would be appreciated. Since I run dual boot with XP, if there is some way I could find out on the other side, let me know that, too. Thanks & have a nice day, Wally
