Tried installing Cat 7.5 on my W2K machine: "Setup could not find a driver compatible with your hardware or operating system." So that's it ? I mean, W2K has been unsupported since 6.6, but up to 7.4 all sets work regardless. And that's damn fine too, since with the last officially supported 6.5 set I had crashing issues in some of my games, which later versions fixed. Is 7.5 really incompatible with W2K ? What is so damn different about XP that I am not aware of ? I was perfectly fine with running a unsupported driver, but I'm not happy with having no more new ones. NV's drivers are still for both systems, I guess I'm done with Ati, next box will have a NV card. And possibly an Intel CPU as well. Too bad, I liked AMD and Ati much better than Chipzilla and NV for a long time. But those times are over.
