I'm trying to install an IBM OEM version (according to ebay seller) Matrox G450 PCI card to an XP system. When I try to run latest or previous driver installation, this card shows up in the "devices not supported" box as Matrox G400/G450 (if it is supported, you will only see one box which is "devicese supported"). I've contacted Matrox support via forum. The advices I got are: upgrade bios, try another system. try a previous version of driver. I tried all of them and this card does not work for either system I tried. I also tried both install with another AGP G450 together and install this PCI card alone. Neither worked. The card has following information: Product code: G45FMDVP32DOE3D PN SN: 80P4527 YL102443B045 version: 7003-0301 REV_A I was wondering if anyone had similar experience or knows what problem is? Thanks for help.
