I have an old motherboard. The problem is that its on board graphics is not working. The motherboard does not detect PCI video card automatically. I have to change primary video adapter to PCI from BIOS. But how to access BIOS when there is no display. Is there any method by which I can force video through PCI video card?.........
Reset the BIOS settings using the clear CMOS jumper and/or removing the battery. By default, it should use an external video card first.
