Hi, I have problem using the AGP slot in my SiS 730S-chipset motherboard. I cannot use the AGP slot instead of the default onboard AGP since I don't find a "AGP VGA Selection" in its bios but the manual shows that there is such option. If I need to download a new version of Bios, where I can download it? There is no web site address on my manual. How do I install it into Bios? Please help! Thank you.
