Grandfather has a PBG3 of the earlier vintage. Currently running 9.2.2 which I installed about December/03, and uses a cardbus card to provide USB port for an epson printer. Recently started giving "Bus Error - Please restart with extensions off" bomb at startup.
Watch the extensions crawl. The one that crashed is the one that occurs alphabetically *after* the last one displayed. You need to figure out which that is and trash its prefs (essentially).
Rebooting Ext. Off, then a restart, gets the machine working no problem. However, the bomb happens again eventually, of course. Not sure about frequency, but I "fixed" the same problem Easter weekend, and it was back today. Machine lives on a desk, gets very light use for e-mail and browsing, so shouldn't be anything loose. Ideas as to the cause of this? Which "bus" is it?! Motherboard bus, loose cardbus card?
"Bus error" is a generic memory access failure. I/O devices are mapped to memory ports, so it could be a driver being unable to talk to a peripheral too. Could be software or hardware caused...
Is the machine about to croak totally? Software conflict?!
Probably not.
Follow George's advice re the USB.
And it's probably worth trying the basic cleanup:
Boot with exts off then trash: CarbonLib Preferences Finder Preferences Mac OS Preferences System Preferences Navigation Services (folder) Open Transport Preferences (folder) and Epson Preferences:<printername> (just that file)
Empty the trash. Run Disk First Aid on all partitions. Reboot. Hit the control panels and Finder preferences to reset them as you want. Then rebuild your desktop database.
