I can’t find a System Board Extension for PnP Bios, for my system. I’m running Window’s ME. I have a Atholon elite 1.2 gig processor and have a Radeon PCI card, My monitor keeps going down and i get a frequency overload error, then i have to reboot.I have the SIS mother board not sure what chip set. I think it’s 630 or higher. I use Pc 133 sdram and also have the sound blaster live sound card. Can you help me. Any assistance would be appreciated. Thank You, Clayton Dammen.
