    the nvidia drivers and AGP mode slider refuse to detect my motherboard AGP settings. where it says 'capabilities', it says 'unkown agp:0.0', and then my graphics cards available AGP modes (geforce4 4200) and says its running at 1x. I checked my bios and it says my motherboard is running the agp mode at 4x, and i really have an urge to fix this problem. can anyone help me? my motherboard is a VIA asus a7m266 (with 4x agp capabilities)
    thank you ahead of time.

    I couldn't tell u off the top of my head what mb it is but i just bought a Radeon 900pro 128 and have the same issue. the board had built in video that ran at 2X but it said when the agp port was used it would override that, which is does, but it is capable of running 4X but it still runs at 2X. there is no option to change that anywhere in the cmos. is there potentially a jumper on the board i have to change? i haven't been able to find any help anywhere for this.

    i actually got an answer if your using a amd a7m chipset...
    "ermmm... The A7M does not have a VIA chipset. It uses the AMD 761 North Bridge, and the VIA 686B South Bridge. So what you'll want to do is install the VIA4in1 drivers, but DON'T install the AGP driver. Then go to AMD's site here:,00.html and download the AGP driver. It's the second one from the top. Install that instead, and see if you get better results."
