I'm trying to get an old PCI video card (Diamond Stealth 2500) along with a normal PCI-E video card.
In BIOS, there is a setting to switch between PEG/PCI or PCI/PEG on startup (PEG is PCI-E Graphics). When I use PCI/PEG only the old PCI card works, when I use the other one, only the new PEG card works.
In PEG/PCI mode, Windows 7 recognizes the card and shows it in Device Manager as Standard VGA adapter, but it shows a warning for the device ("This device cannot start. (Code 10)").
