Noticed that an HP USDT 478M motherboard with i865G Graphics has a DVI 34-pin header, and a blank spot in the shell that can push out. Searching google for a while I can not find a pin-out for this header, or any drop in upgrade. It does say P65 next to the connector if that helps. Gave this to my son to play classic games on, and it would be great to hook it up to a 1080p wide CRT we have with that DVI. It only has a very small PCI slot that uses a specific length card HP 319958-002 HP nVIDIA Quadro4 100NVS, and all those selling it want more than you could just get another whole P4 machine with a 64mb graphics card several times for their price.

Thanks in advance for any information!
