I had nothing but problems trying to run 2 ATI cards. In my case a Radeon
7200 (agp) and an Xpert98 (pci).
To get everything to work properly
1) Install agp card by itself, insure everything works properly
2) Add pci card to system and install ONLY the driver. The full install
seems to be too stupid to look at all ATI cards in system and appears to
only notice the pci card and it's lack of mm features etc. so removes the
existing software the agp card installed!!!
Under 98SE this still resulted in the Xpert's driver deleting the "TV-Out
enable/disable" dialog (presumably as it loaded at bootup) which meant I had
to always disable the 2nd card and reboot first to enable TV-Out. After
booting I could re-enable to 2nd card and the TV-Out control dialog
remained???
Under XP it was no problem.
Notice the bs one has to go through to update drivers because of having to
first remove the 2nd card, made it a real pain in the butt. I've eliminated
the problem by using an old Cirrus Logic card for the 2nd display
(documented as a supported 2nd card in displays.txt 98SE has).
