I have a PowerBook G4. I blessed an OS 9 system folder, unaware that my PB couldn't boot OS 9. 
I also have a DVD in the drive, that won't eject using any method during boot.
So! If I start my PowerBook in firewire target disk mode, and re-bless the OS X system folder using --setBoot, doing all of this on my MacBook Pro, will that mess up my MacBook Pro, making it look for the folder on my PowerBook, or will it work the way I want it to and make my PowerBook boot to OS X again?
Thanks
