I just bought a 32Meg Riva TNT2 Video card. I have disable the onboard video card in bios and in windows (win2k). The problem I am having is when I change the value "Assign IRQ to VGA" in bios to enabled. It works when I boot up. However when I reboot or shut down, the setting changes back to disable. I replaced the CMOS battery, but no luck. Any help is appreciated.
