I posted a few days ago about B&W G3, 9.2.2 freezing when checking "Devices and Volumes" under System Profiler. Messed around w/ extensions and could get it working, but then couldn't get Old HP Deskwriter C (slow but solid) printer to work (w/ Keyspan serial card)which had worked before. Altered extensions settings in attempt to resolve, and now it's totally screwed up--machine freezes immediately after startup. Same result if bold down space bar on startup. If hold shift on startup, end up w/ blank bright blue screen. QUESTION: How can I get to extensions manager to revert to Base or All 9.2.2 settings? Another clue--running a 17" crt studio display which has drivers. Have considered hooking up to a plug and play monitor which may not have driver issues, but thought I would first ask for help. TIA .
