The board only has 2 PCI slots, which may make life with an 0404 difficult. Then again, you might be able to get it to work. If you don't have any driver installed at all, then with the computer shut-down, remove the 0404 from the computer. If there is a driver installed, remove it (un-install). You might also open the Hardware Manager and "un-install" that "Creative Audigy". Boot into Windows without the 0404 in a slot. That should clear the Windows' registry. Since the Windows stuff now says "Creative Audigy...", and there isn't an IRQ assigned for a WDM Audio Device (or something of that nature) in the IRQ list, then the computer identified your 0404 as an Audigy. That can happen if you don't cancel the "New Hardware Found..." wizard after you've inserted the 0404, or if you install Windows with the EMU card inserted in the slot, or if the card is damaged.
After you've re-booted into Windows without the card, shut-down and re-insert the 0404, only this time, put it in the #2 PCI slot instead of the #1. Leave the case open for that "just-in-case" scenario. Boot-up into Windows and cancel the "New Hardware Found..." wizard. (If one doesn't come up, then Windows has once again identified the card as a Creative Audigy, which isn't good, and you'll get nowhere. Post back if that happens.) Install the EMU drivers from the EMU
