I have just purchased Powerbook G3 from someone here on ehmac and will receive it this week. This may be a silly question, but I am hoping someone can humour me on this one. The drive will be partitioned with OS 9 on one and X on the other. I have never used either of these, nor have I had a partitioned hard drive. How do I start up in one or the other? Also, how do I switch between them? And, given my complete ignorance, is there anything else I should know or that might be useful? Thanks in advance.
