Hi, I am completly newbie to Mac. I have been giving a G3 266 with half the operating system (8.6, but no browser , network, stuffit, nothing...) I want to install a new system from scratch (clean install ?). How do you do this in a Mac? I have an original Mac OS 9.0.4 cd from a G4. I can boot with it but I can not install it. Is it in Mac that there are different versions of the software for different procesors?. I also have a cd with OS X.1, but it says that I need to have version 9 previousy. Is this an upgrade CD, or is this normal in Mac? any help will be very appreciated .
