Why bother with soundcard-drivers at all (and yes, all their links point to the unwanted Driver Easy package) when the file in your link, PW4031.zip, is available elsewhere on the live & archived web.

None of those drivers worked. After installing the SoundMax and the Cirrus ones Windows 98 kept autofinding them and installing those over anything else upon OS start / when I asked it to find more hardware. After a few ghost sessions (I have two of these systems, I had an image stored) to restore the baseline, and spending far too many hours on this, I threw a CT4810 at it, disabled the onboard sound (which worked fine in XP) and called it a day.

Strange, as this board came out in 2001 - I don't see why the OEM didn't provide Windows 98SE drivers, as the OS was only 2 years old at the time of the motherboard release.
