Hi there List-Pals, I have an old G4 dual processor power mac, 450 each processor. my mom gave it to me a while back when she got a newer one, and I do not know the actual model name, though I do have the serial number. I found a chart online about firmware updates, but I think it only has newer models, though I'm not certain (they use the code names and I don't know mine). I currently have OSX 10.2.8, and I have a disk to install Tiger. The instructions said to update my firmware before installing. Anyone out there have useful factoids on this??? Thanks!
