Hi i have a Compaq Presario SG3100UK Desktop PC and i want to enable the onboard card when PCI-e video card is installed. at the minute all I see in deviece manager is the PCI-e video card even though in the bios the onboard is set as primary. From what I am reading PCI-e slots disable onboard card on most PC's. My quesion - is there a bios mod to overwrite this?
