Asus P4B266-C thinks I have a non 1.5v AGP card, PLEASE HELP!

I've got a Hercules 3d Prophet 4500 64MB, which is a fully agp2.0 compliant 1.5v card... but the AGP warning light comes on and won't let me power on the system.. any ideas anybody?

doh... figured out what the problem is. my videocard only operates at agp2x and the board only supports 4x.. dammit!
