I found this tidbit of information when getting information together for my Build Your Own Computer class. Take the AGP out of BIOS, it is the secondary card if you have a PCI with it. Boot with the PCI and you should be fine!
Multiple Display Support in Windows 98
Windows 98 provides support for using more than one display device at a time - you simply install a separate PCI or AGP graphics card for each additional display you intend to use. With multiple displays, you can expand your desktop, run different programs on separate displays, even play some newer games with multiple views. And each display can have a different resolution and color depth!
Note that, under Windows 98, one graphics card is automatically designated by the system as the primary graphics card. Each additional graphics card is designated by the system as a secondary graphics card. If you are installing more than one graphics card, you need to consider the following:
· If you install both a PCI and an AGP graphics cards in the same system, the AGP card will become the secondary graphics card.
· If you install two or more PCI graphics cards in the same system, the primary card is typically the one installed in the PCI slot with the lowest number. This is typically the PCI slot furtherest from the computer's ISA slots. Consult your computer system manual for help in selecting a slot.
In order to display two video output at the same time, you need to use a video card with multiple video output, such as the Matrox G400 32MB dual head.
