My problems are twofold: I have a system that's dualbooting Win2K & WinXP. In 2000, I have the monumental task of trying to find some Win2K drivers that will allow me some rudimentary kind of performance out of the PwrColor Radeon HD 4650, so I can get out of 640x480! Can't believe there aren't some generic Microsoft drivers that would give me better resolution than THAT!! I could swear there were with Win98! And in XP, although I've got nice resolution, no matter what I do, every time when I start WinXP, I get this ATI error message "Could not load file or assembly `MOM.Implementation' or one of its dependencies. The system could not find the file specified." And if I try to load/run Catalyst, I always get this ATI error message "Could not load file or assembly `CLI.Implementation' or one of its dependencies. The system could not find the file specified." Any assistance you could offer would be greatly appreciated!! Thank you!!
