I posted a thread about my powerbook which has gone haywire. To ensure it was a hardware issue, I installed Jaguar on my firewire external. It installed fine then booted up. The password reset utility shows no passwords or users installed, but when I start up this new install of OSX it says "other" for the username, and when I try to login or try various passwords the window just vibrates and resets the field for me to try again. Any ideas?
