I've had to upgrade from OS8.6 to 9.1, and then 9.21 on my Blue & White G3 450mh, 1 gig ram, and , where i found 8.6 was rock stable, i'm having all sorts of boot instability problems with 9x..is this common (i mean is it more buggy than 8.6 naturally?)... On boot, often if the G3 has been off for more than a few hours, i get a type 10 error, forcing a restart, after all the extensions have finished loading and it's trying to load the finder..or else it gets to the desktop and starts blinking, loading and unloading the finder repeatedly, or else , if the finder does load, i get the message that the finder has 'unexpectedly quit', despite the fact that it clearly hasn't ...generally after two to four restarts it boots up fine and then it works just fine... Before I did the 9.21 upgrade from 9.1 I would get the 'unimplemented trap" error on boot and then clicking restart would give me 'system error', then a third reboot and it would boot fine (usually).. Yes, i've shuffled my extensions around, and tried to remove all the non-native extensions (but it's hard to tell if an extensions PowerMac native or not!) Anyone run into this..what did you do? A clean install is for me a last resort as i've got a huge system folder and it's clear that it's not the extensions, but the finder somehow that's buggy.. Thanks for any help

Check the Apple Site for Firmware updates, I'm pretty sure you need one when adding 9.2. Also consider a clean install, a pain I know, but a stable system is far more attractive. A Clean Installation renames your current system to previous system folder. You can copy the control panels and extensions across at your leisure checking for problems as you go. Remember 9.2 is different from 9.1 loads of bits no longer work the same. Good luck

Thanx..i think it mighta been a buggy extension as it's better now after lotsa "extension manager" time ..i am curious as to how 9.1 and 9.2 are so different, however, as i've heard that mentioned before...had the problem in 9.1 anyways so the difference wasn't the reason...wonder what they are, tho... As to the firmware updates..i've been holding back as apparently one of them supposedly disables your ability to apply a G4 chip upgrade afterwards..not sure which one though... Know anything 'bout that? Thanx....
