easiest thing to do: get the video driver cleanup utility from the omega drivers, run the cleanup utility, install the dna drivers, save the atioglxx.dll file, run the cleanup utility again, then finally reinstall the catalyst drivers.
unfortunately, the people that made the .exe file for the DNA drivers are using a really weird compression format that not even WinRAR can understand. so, you're going to have to take the above steps to get the lone file. kinda sucks, don't it??
See the struggle of the faithless lot as they negate their time
How low to sink to the depths of their frame of mind
