I installed two Nvidia Quadra FX1700 in X8DA3. In Windows XP, one of the two graphic cards is shown as the PCI device with an “!” mark in Device Manager. There is no video output from the card in question. The BIOS is the latest from the website.
You need to upgrade the BIOS to the X8DA31.125 (build date 1/25/2011) or later.
