Answer:
The secondary video card isn’t booting because it can’t access the resources it needs for proper initialization. If you’re using two different PCI video cards (which is common on an older PC), try swapping those cards to different slots. If you’re using an AGP and a PCI video card, the PCI card may need to be set as the primary video adapter.
Check your BIOS setup and see if there’s a setting that determines which video device (AGP or PCI) should be booted first. If you have an AGP and a PCI adapter, try reversing the boot priority; for example, direct the BIOS to boot the PCI device before the AGP device.
It’s usually best to have the AGP video card set as the primary device because the AGP card will typically offer a far better performance than a PCI device.
If you reverse the initialization order and the problem disappears, you can try to replace the PCI card with a newer model that will initialize properly when the AGP card is set as the primary device once again. |
