As the title says, has anyone installed 2 of the ATI Radeon 3870 (mac edition) cards and get crossfire mode to work successfully in XP under bootcamp? I've been trying to for a few days now with no luck! The drivers for bootcamp on ATI's site won't install on my machine for some reason and when I use the normal xp drivers (successfully) I can't get the crossfire option to show up in catalyst control center. Also, in the catalyst control center, it only shows the primary card as enabled and says my other is disabled. However, they are both enabled and working just fine according to the device manager. Cards are installed in 1st and 2nd slot. I'm totally stumped and getting very frustrated. Any thoughts?
