So the older windows drivers don't work when you try to install or what? A while back I was working on a motherboard with integrated audio (soundmax I think) with xp drivers but no Vista drivers at the time. I could not get the xp drivers to install in Vista no matter what I tried. But oddly enough, if I just did a driver update in vista, and pointed it at the old xp partition to look for the audio drivers, it managed to find and install working ones just fine. I have no idea what the difference was and it was an awful kludge, but it worked! (surely there is an easier way than setting up a dual boot though)
