Yesterday, I installed a new (to me) Aopen AK77-8XN motherboard in my computer. I also installed an 80 gig hard drive (newly formatted), a Soundblaster Live! sound card, a Belkin wireless G card, Windows XP SP2, and a Diamond Radeon 9550 video card. I then installed the latest VIA Hyperion drivers for the mobo. With the VIA AGP driver installed, the display turns to garbage so I had to uninstall it. Next I installed the latest Catalyst drivers for the video card. Everything seems to be working ok, but when I open the Catalyst control center, it tells me that the video card is running with PCI read and write enabled and AGP mode disabled. Both the mobo and the video card are supposed to be AGP 8X capable. The mobo bios says that only AGP 4X mode is enabled and I can't change that field. There is a later beta bios that was introduced for the Sempron processor, but because it was a beta, so I didn't upgrade. Any ideas on how I can get this card to operate in AGP 8X mode like it is supposed to?
