I've got an Asus P2B mb that apparently is 2x AGP. The bios hasn't been
updated for years. Is it possible for a bios upgrade to change the AGP slot
from 2x to 4x?

No.

A mainboard using the 440BX chipset only supports AGP 1 (1X and 2X).

I've used an nVidia Geforce 4200 card (AGP 2) in a BX system. It worked
fine.

I have read suggestions that some AGP 3 cards are back compatible, but I
have no personal experience with that.

No, the chipset only supports 2X. Most newer cards should work on that
board though, unless they support 1.5V only (GeForce 6600GT is one of
those that won't work).

No. 2x cards use a different voltage than 4x cards do.

Most definitively not. This is a hardware question, not something that can
be changed in software.

Well, this is sort of true.. for the card to actually run at AGP 4X, it
will be using 1.5V signaling voltage, however most AGP 4X cards are able
to fall back to AGP 2X using 3.3V signaling if this is all the board
supports.

As no one has mentioned there are also slots cut into the VGA card that will
not allow the installation of an incomatible VGA card.

It installed fine so the slots were compatible.
