Q: I have 939Dual-SATA2 / 939Dual-VSTA / 939A8X-M / K8A8X-M / K8Upgrade-1689/K8Combo-Z motherboard. When using Nvidia 7600GS/6600LE/6800GS/7800GS "AGP" card, I am not able to install the VGA card driver. How can I solve this?(11/19/2006) A: This problem will occur on some AGP cards which does not use native AGP chip, but use native PCI-E chip with an "PCI-E to AGP Bridge" to become AGP interface.
Please set "AGP P2P Deep Fifo" to [Enable] in the BIOS. (Advanced>Chipset Settings>AGP P2P Deep Fifo)
It may need to upgrade the BIOS for this option:
