I'm currently having a problem trying to run two graphics cards at the same time. The two cards I have are a Radeon x800 XL PCIE and Radeon 9250 PCI. I purchased the 9250 simply for its TV-Out capability. I currently have the other card hooked up to dual monitors. What I am trying to do is add a TV as my third display, preferably with an extended desktop.
What is happening is that I cannot get the two cards to co-operate together. I only get the two monitors if I choose to boot the x800 from my BIOS, and only the TV if I choose to boot the 9250. Other guides that I have read said that it is possible to change which boots first, however, I only have the option of booting one or the other. Is there a way to run them both at the same time?
When I visited This link a user was trying to do something very similar and said that by making two BIOS changes, he was able to get his setup working: 1. I had to turn on the option "Allow PCI VGA card to request IRQ"; and 2. I had to set the BIOS to use the PCI card as the first video card.
Is there something similar I can do?

I also called the ATI tech support to ask this same question, though the person I spoke with wouldn't give me a recommendation, she did say that she didn't think the 9250 would work for what I was trying to do. Is there another that would, however, without having to buy a Crossfire compatible one? Other guides that I have read said that I do not need SLI or Crossfire cards.
I get the message: Windows has stopped this device because it has reported problems. (Code 43) when either card is booted up.
