looks like whosdat wants you to verify that the old video card will still work in the motherboard, cause...
video cards have to function at a basic level (without the drivers i think), otherwise how could you see BIOS ?
If your new card won't even work in BIOS, I'd be inclined to think it was bad.
Inspect it for jumpers, maybe you need to set one or something. Also look for physical damage, burn evidence, etc...
Is it seated properly in the slot ? Is it locked ?
If it were another piece of hardware, I'd say install the drivers first (using the old card) and then change the cards out, so the new drivers would be available on boot. But I can't believe a video card needs special drivers just to display BIOS.
