I bought a quicksilver powermac G4 the other day to run OS9. It had a clean install of 10.4 on it and no matter what I do it will not boot from my OS 9.2.1 disc. I've tried holding "C" when booting, holding "Option" when booting and selecting the CD from the boot menu, and going to system preferences > startup disk and selecting the CD as the startup disc. Nothing has worked. When I try to run the installer from the CD it gets about 90% done and then I get this error I've heard that I might not have the right firmware to run OS9, but I don't know how to check what version I have, nor do I know which one I need. What am I doing wrong?
