I have the identical machine. The bottem line is that CMBO runs using rave instead of open GL for graphics. Although classic runs 99% of programs very well - there are some limitations - and CMBO is one of them. I'm happy to report ,however, that the game runs beautifully in Os 9.2.2, and that the GeForce 2 MX is powerful enough for me to run all the mods I want without any slowdowns. Although I use Os X exclusively now, I still restart in 9.2.2 to play CMBO - not that big of a deal. As for the classic rave extension, and having the Os' on different partitions ----- don't worry about it. Leave the extensions alone - it plays great the way it is in 9.2.2. As for the seperate partitions for different operating systems - this is a big debate on apple-centric message boards. I run both on one partition and everything works great ---- dont forget, this is the way apple sells them afterall - with both OS' on one partition. I hope this helps.
