I'm back with my friends ex-Compaq computer probs. The bios upgrade from compaq to gigabyte went off fine. The udma 100 hdd hauls butt at udma 66. Now since its so much faster they would like to run applications which use more than the 8mb shared system video memory. I didn't see any way to disable the onboard video in the new bios. There IS an option initiate 1st- agp or pci video. Will this board [Gigabyte GA5SMM -SiS 530 & 5595 AGPset] accept a pci video card?
