I tried the onboard sound, but the performance was bad at best, and I sacrificed a slot for a real sound card. Diamond Supra Express 56KFlex Modem. I am using Noton utilities for Windows 95. I had to remove the extra 128Mb memory module. Once it was removed the benchmark reported a normal 400MHz score.
Support is nonexistant.
However the website does have updated drivers for Windows 98 and NT 4.0. However the AMI Bios Flash utility on the website does not work. I had to search the net for the newest utility. The manual is very poor as far as explaning how jumpers should be set. I had to guess a couple of times as to where pin one was on certain jumpers.
