We need to install Matrox G550 (PCIe 1X) dual head DVI cards on Intel 915GEV motherboards with onboard video. If we install the card "normally" by selecting the PCI as primary, the card works but device manager shows a red x on the onboard video and CMOS can't be accessed on bootup. This isn't an acceptable solution, and we're waiting for a better response from Intel, which so far says the 16x PCI slot must be populated by a 16x card. Since the cards and mbs have already been purchased, it would be great to find a solution that doesn't involve different graphic cards or mbs. Are there PCI 16x blanks available?. We know about the ADD2 Cards that give you a single DVI on the card and uses the VGA onboard for the dual head capability, but we need to run 2 DVI's.
