The catch is that for several reasons I am unable to use the CD drive to perform this installation, and am thusly relegated to using USB (I have no FireWire drives or other PPC Macs with which to perform a Target Mode install.). I would like to either reinstall Panther, or upgrade to Tiger. I have a PowerMac G4 (AGP) with a working copy of Mac OS 9.2, and a corrupted copy of OS X 10.3.
