I'm running Windows XP and trying to set up dual monitors. I have two older ATI PCI Video Cards. The primary card (the one in the PCI slot that takes priority over the other one at bootup) is an ATI 3D Rage Pro card, 4MB of video ram. The secondary card, which I placed two pci slots down on the motherboard, is an ATI 3D Rage II with 2MB of video ram. When I boot up, Windows XP is able to detect both cards, but it is unable to use whichever card is the secondary one. Looking at my device drivers, I see the yellow circle with an exclamation mark letting me know something is up. It says "This device cannot start: Code 10"). I'm assuming that it has the correct driver for both cards, because I can use either one as my primary display (by swapping their PCI slot locations). Since they are both older cards, I read something about certain cards requiring VGA BIOS to boot, but only one card can use the VGA BIOS? My best guess would be that this is the case, and the card that can't access the VGA Bios (whichever one is the secondary card) cannot start up during the bootup process. I looked at the jumpers on booth cards, and the only one they have is labelled INT, which can be set to either ENA, or DIS. I'm assuming that has to do with Interupt assignment, although I'm not sure if it would help my problem or not. They were both set to DIS, I tried setting the secondary one to ENA but it didn't solve anything. There is another lable on the circuit on both chips, right next to the INT, called VGA. Unfortunately this section has no jumpers so I can't change that on either card. I've also tried booting with "Plug and Play OS" turned on and off in the Bios settings, with no luck. Is there any way to get booth these cards working together so I can set up a Dual Display?
Thanks in advance,
