Well, I think I may have found a workaround. I was unable to boot into 9.2.2 again tonight due to the errors, and after some playing around, I booted off of my Panther CD and switched my startup disk to another copy of 9.2.2 on another partition. This time things booted fine. I started checking into details, and noticed that the version of the Mac OS ROM in the system I normally boot from was 9.0.1, while the version in the system that worked was 8.7. I moved 8.7 into my normal system folder, restarted, and things booted just fine.<br><br>I'm not sure if using the older ROM will break something else, but it seems it *will* allow you to boot even if the monitor is throwing the USB Setup Errors. Not sure why that behavior would have changed in the newer version...<br><br>
