Old PCI Video Card and PCI-Express ATI Radeon HD 4200 Pro Living Together
- by Adam Driscoll
I have two video cards installed in a Dell Optiplex 745. The PCI card is from 2001 and I was hoping to be able to install it, allowing me to have 3 monitors. The Radeon is already running two itself. The problem is that when I boot the box with default BIOS settings the PCI card displays video to the single display but not the other two.
In device manager I can see that both video cards are visible with drivers loaded correctly but underneath monitors I only have a single Generic PnP monitor from the VGA connection to the PCI card.
If I switch the BIOS setting to force PCI-E I get the Radeon to display to the two other monitors. When I check device manager with this configuration I see that the PCI card displays an error saying the driver could not be started.
Any ideas?
