Sure, the active system components for your OSX are in a folder called System. Trash that and OSX can't boot. Shouldn't affect OS9 directly, though. If your OS 9 won't boot. The Flashing ? means that your Mac can't find an active (blessed) system. Boot to a startup CD, such as your OS 9 install CD. Once you get to the Finder, Open the System Folder. that's where your active components for OS 9 are normally found. Look for a System and a Finder. Also, your system probably needs a Mac OS ROM, also in the System Folder. those are the files that MUST be there. Any missing, someone here may be able to help you get good ones from OS9 install CD. If you do find all those, then move Finder out of System Folder to Desktop, drop there, then pickup and move back to System Folder. That short action should Re-bless the System Folder. Go to Control Panels and open Startup Disk, click on volume to make sure the volume is selected for Startup, close. restart. If nogo on that, then run some kind of disk repair tools from a startup CD.
