I know this is off topic for this list but I am desperate for an answer. I got a used PowerPC 6400 for my class. It doesnt have an OS on it. I have a disk of OS 8.5. When I start the computer it starts with the CD but it comes up with an error saying the file map is not good. Can someone tell me how I can reinitialize the hard drive so that I reinstall the OS from scratch. I come from a Wiindo$ background so I just dont know how to do this. Please help me out so I can give this computer to my students to use. ThanksRuss Edwards russ.edwards at spymac.com www.spymac.com ---- Get Urchin 6 On Demand web analytics.
