Having both OS 9 and OS X on the same volume should not be a problem unless you go rummaging around the OS X system in OS 9. OS X has many mechanisms to protect itself from inadvertent damage, none of which are recognized by OS 9.

Please excuse my confusion. From your previous posts you apparently do have a set of OS X 10.3 Install CDs. I rashly assumed those came with your Mac. In any case follow my instructions using the OS X 10.3 install disc 1 that you have. It will work the same way.

If we knew what it was we were doing, it wouldn't be called research, would it?
