Dave, I think you missed something. If you only had an AGP card, it would still boot up, since, even if it is set in the bios to look for a PCI video card first, it will just go on to the AGP bus, once a PCI card isn't found. (How's that for a way too long sentence? My grammatical skills deteriorate after a very tiring day)<g> It will then find the AGP card, and voila, you will see an image on the screen. (This assumes you begin with one card installed, which is the preferred way, anyway, just so that what you experienced won't happen.
There are various stages of boot up, and the first, text based stage, only needs one card/monitor to boot with. You just can't place both cards in the slots, and then only hook one of the monitors up like that. Since the BIOS "found" that first PCI card, that's the one it wanted to boot with, by default, and you didn't have a monitor hooked up to it.
Good information for the future, should you mess around in there again.<g>
