    I have my XFX 4890 flashed, and it works great in OS X. The problem is that I can't get it to recognize in Bootcamp. I am using bootcamp 3.1, but when i try to install the ATI bootcamp drivers/catalyst it won't let me because it says it can't find the components.

    Initially my device manager said my card was a vga enabled device with a yellow question mark, but I installed the windows xp drivers and now it recognizes it as a 4800 series card but still I can't boot from it or install catalyst.

    I have a macpro 1,1, OSX 10.6.3 I have been trying for days to get this working, please any help or advice would be greatly appreciated!

    no thoughts?

    Nobody has any thoughts or theories? Even if you don't know how to fix it, and thoughts would probably help....

    why are you using bootcamp drivers? there is nothing magical with them. it's just a collection of old versions of drivers. always download the latest ones from manufacturers website.

    I tried that, and the manufacturer display drivers install just fine....but cataylst doesn't install. It fails every time, and I have even reinstalled windows XP thinking maybe there were conflicting apps/drivers. I have even installed my friends unflashed XFX 4890 into my computer and tried, and still nothing. In the end, my computer still won't read my video card. But it works in OSX. Its so confusing!

    But its really good to know that the ATI package is useless, I was wondering why they had those posted!

    Try one of the Driver Cleaner type programs.

    Get rid of ALL GPU drivers, ATI or Nvidia.

    Restart and reinstall drivers, make sure they are for XP.

    Yep, that worked! Looks like bootcamp installed some faulty or old drivers. I just had to clear them out and reinstall them because it wasn't letting me update them. Thanks guys!
