According to some user feedback, we found out that VIA PT880 PRO/Ultra chipset does not support GEN2 mode VGA card.
In order to resolve the issue, you would have to install the graphics card on another machine, acquire the PCI Gen 1 Firmware from your VGA vendor.
An example is that ASUS 8800GT card. After flashing GEN1 mode BIOS for ASUS EN8800GT PCIE card, it works fine on PT880 PRO/Ultra chipset motherboard.
