I have a Biostar M7VIK Socket A mobo with latest website BIOS (0326B), which is supposed to feature 8x AGP support. I recently purchased an ATI/Sapphire RADEON 9250 which is 8x AGP compatible. The card works with the mobo, but I cannot alter the AGP mode in the BIOSit is locked at 4x AGP. What must I do to modify it to 8x AGP? This is quite annoying, especially considering that the one of the mobo's supposedly uber features is 8x AGP.
