I have a PowerBook G4 --- silver keyboard, power button is in the middle of the right hand bezel, and the label in the battery compartment says 1.25GHz/512MB/80G/SuperDrive/BT/APX/Backlit KB. I can't identify the model more than that as for some reason Apple never decided to label this machine.
I can't find a MacOS 9 image which will work. I've tried the universal boot CD, the CD for unsupported G4 Macs, and the Powerbook Titanium 1GHz image. I get 'Bootinfo is not compatible' errors when booting from OF, except for the Titanium image, which does load the ROM but then errors out with 'checksum error. Loading ELF. DO-QUIESCE finished'. multi-boot won't touch the CD images.
What is this machine, and can I get MacOS 9 running on it?
