I once had a quite similar porblem, but the Os9 CD only hanged when i started the disk utilities. In the end it was a corrupted partition table on my hard disk. Actually it was a bug in disk doctor - there was an endless loop over partition entries... I could fix my problem using a linux for ppc CD. If you are not familiar with linux i suggest you try to boot your mac with another hard disk. good luck Till marco santos wrote: > Hello, > > I hope somebody will be able to help me on thi matter > because I have been struggling over this for two > weeks. > > My profile: > > Powermac G4 AGP Graphic 450 Mhz (Sawtooth) > Running OS X Panther 10.3.9 > > I bought an processor upgrade for my computer @ OWC. > It's a Dual 1.0 Ghz.
