Trying to reinstall Poser 4, both thru OS X Classic and booting straight into OS 9. First problem: the P4 installer can't kill 'USBserver' applet, and aborts install. Os 9 is now refusing to boot up on its own (system pref/startup disk/etc.) Repaired permissions, ran Applejack, you name it I'm stumped. I don't want to whistle up CL, 'cause they're just going to tell me to upgrade to P5. I accidentally nuked my Poser folder (AND my entire 5 gig runtime) so I'm not feeling too well. Daz Studio's latest build will not install on my machine either! It dumped it into the trash and when I DID manage to get it installed, the runtime's contents would not kick in upon figure load. Guess that's more of a D|S issue than P, but thought i'd mention it anyway. Rig: G4 450 OS X 10.2.8 with OS 9.2.1 1gig ram 60GB hd with plenty of room to play in... No hardware problems...everythign checks out otherwise.

It sounds like you corrupted system nine in the process of installing P4. The old adage is to re-install sys 9 clean. While it is still clean you might want to try the install of P4. Then you can add your inits and other prefs and what nots to the system. God knows it might work. I wish you luck

Run Diskwarrior prior to re-installing OS 9. Check for bad users, run in safe mode, try to recover Poser 4 folder, etc. If you have a Keyspan USBserver, any 3rd party USB or ethernet devices or any other machines connected, disconnect all of them, and turn off their associated software, if possible. It sounds like something is dumping a kernel extension in there that is screwing up Classic and/or the Poser installer. However, if you backed up Poser 4 from a previous installation, it doesn't need to be re-installed. Just drag the backed-up Poser 4 folder to your clean OS 9 disk (or apps folder).
