My system is a P4 2.53 on an Intel D845PEBT2 board.
The instructions with the board says the board only supports 1.5 v AGP
2x/4x cards, but not 3.3 v cards. Does this mean I have AGP or is it
AGP 2?
As far as I know there is no "AGP" and "AGP 2", at least not the way you're
specifying it. There's AGP 1x, 2x, 4x and 8x, and voltages running between
3.3 and 0.8. Generally the 3.3V cards are the least compatible with
anything. The slots and cards are supposed to be keyed so you can't plug the
wrong voltage into a slot, but I hear some 3.3V cards didn't follow the keys
properly and can be plugged into a 1.5V slot... thus damaging certain
motherboards. Basically if your card is AGP 4X it will be safe for your
motherboard, but if it's 2X there's a risk it might be 3.3V.
Then of course we can get into the whole short-lived "AGP Pro"
specification...
