Dual Monitors - Video Cards Not Working

Have an Acer desktop with an integrated video card which is an S3 Graphics VIA/S3G Unichrome Pro. I have a separate AGP video card that I installed trying to set up dual video. Using Windows XP.

The AGP card started working and disabled the integrated video card, and I did not see the integrated card anymore in device manager, only the AGP card.

The bios setup for changing the display startup has 2 options -"Onboard/AGP" and "PCI Slot". Changing this option had no effect.

Seems my problem is that the computer sees either the onboard video card or the separate AGP card and I need a separate PCI card instead of the AGP card I now have. Does this seem right?

Also, if I need a new PCI card, does anyone know about any compatability problems with the S3 Graphics card I have ?

Thanks, Don
 
So you are trying to run 2 monitors off of an AGP graphics card and an Onboard graphics card? Is that correct?

Im not sure how possible that is, as you said, i think an AGP card disables the onboard graphics.
If you AGP card has 2 monitor connections you can run dual monitors off of that one card. or you could buy a cheap PCI card to run the secondary monitor off of.
 
yeah you need a video card that supports dual monitors i believe. Or two video cards that are NOT on-board.
 
Yes it needs to be a card that has 2x VGA or DVI ports,you cannot run one card with only 1 vga or dvi port and run the other monitor of the intergrated port as it gets disabled as soon as you put a gfx card in.
