Short & quick:
PowerBook G4 w/OS 9.2 & 10.4(? - upgraded from 10.0) won't boot up after aborted browser install.
My sister was trying to upgrade Netscape Navigator 4.7 to 8.1 on her OS 9.2 (she is running a dual boot OS 9.2/10.4(?) PowerBook G4 (15" screen, unknown GHz/MHz, but I am attempting to track that info down). The system locked up and after awhile she powered down the totally unresponsive system.
Unfortunately I wasn't around to advise her before/during/after the upgrade attempt.
Now, on attempting to boot up, all she is getting is a question mark GUI prompt - obviously alerting the user to the inability of the PowerBook to initiate a bootable OS.
Any suggestions on appropriate course(s) of action to get the system up & running would be greatly appreciated.
