I noticed my new Optiplex 330 came with two video cards:  a Radeon HD2600 in DVI, and an onboard VGA card.  I would like to use both simultaneously, but when I plug in two monitors and start the computer, only the onboard card turns on and generates a bios error that I am plugged into the incorrect video card.

Is it possible to have both monitors at once with the cards and bios available?
