Dual Monitors using AGP Card and On-Board Video

I am having trouble configuring dual monitors using an agp card and
my onboard video. I know there must be a way to get this to work as I
have done it in the past, just can't remember how. Any advice?

Usually the motherboard automatically switches input to the AGP card
if installed, and disables onboard video. I have never heard of
running dual-monitors this way, and if possible, would require some
way of leaving both enabled and disabling the bios switching system.

Sorry, unless there is such an option in the BIOS, I don't know of any
way to force it. You could contact the company that made the board.

Most onboard video cards use the AGP interface themselves, and as I
understand it, only a single AGP interface is possible due to
architectural/design issues.

In other words, a dual-head AGP card is the way to go.

On the typical board with AGP slot and integrated video, the
integated video is running from a logical AGP port. Because
AGP is a port not a bus, you couldn't run both even if there
were a way of trying to trick the bios.

The typical solutions are either:

1) Pull the AGP card out, install a PCI video card and use
it plus the integrated video.

2) Use an AGP card with dual monitor outputs.

3) Install a PCI video card and use it plus the AGP card.

4) Pull the AGP card out and install a PCI card with dual
monitor outputs.

If you install a PCI card you would have to decide if it
should be considered the primary display device and make
changes to that setting in the bios if required.

I guess I was wrong, thanks for the info all!
