I recently came across an old 500 G3 ibook and am having a bit of a problem with it. everytime i turn it on, a folder appears with a flashing question mark. obviously i need to reinstall whichever mac OS, but will the hard drive still be good? my friend told me about being able to boot and install a mac os from a pb to another mac. they were connected with a standard 4 pin firewire he claims. has anyone heard about this? whats the fastest way to get this ibook up and running
