I bought the CFS3 cd to get ready for P3, and when P3 came, I installed using the copy files from disk option and it did great and is running great. But I hate having to put the stupid CFS3 cd in every time. My dvd/cd-rom drive is very noisy, so if I just leave the cd in, it makes a racket every time I start up the computer. I can live with this, but I've seen several no cd cracks for CFS3 and wondered if I installed one of those whether it would damage my OFF install. I don't have CFS3 installed, just OFF, and whatever files from CFS3 it needed. If anyone knows whether the no-cd crack for CFS3.1 will work in this situation without messing everything up, let me know.
