So I have an old iMac G3 (500mhz). Long story short. Running 10.something. Tried upgrading to 10.4 but had to update firmware from 9.2. Had 9.2 installed but firmware upgrade failed; no idea why. I said screw it, plugged in the firewire and wiped the drive from my Macbook Pro, thinking I could just run a clean install of everything. I reformatted in Mac OS Extended (Journaled) which I now learn is wrong. THE QUESTIONS: What format should it be to run the classic environment so I can reinstall 9.2 do the firmware upgrade then proceed with my install of 10.4? How the hell do I do this now that the drive isn't responding to any format attempts from my Macbook? Is there an easy work around? /Yeah, I'm a noob. Sorry for cluttering the board.
