Well, I have acquired disc images, which all seem good, and I have extracted the restore disk image parts from them, which, using OS X Disk Utility I have converted to a single large disk image. This image passes checksums just fine; but it won't restore properly. I have tried restoring it to a FireWire hard drive, and it gets to the very end, then complains of a checksum error (even though all the individual parts before doing that restore pass checksum.)
Yet if I do a file compare of the mounted restore image to the restored disk, it all matches.
I can boot the disk with my B&W G3 just fine, but trying to boot either OS 9.2.2 or 10.1.4 crashes on my iMac G4. (9.2.2 has the screen go black when the progress bar hits about the 1/4 mark - which is the same symptom I see from nearly every attempt to boot OS 9 unless I get EXACTLY the right boot set. 10.1.4 boots through the startup screen, then shows a "scrambled" screen in about a 100x100 pixel square in the upper-right corner, with just blue background image the rest of the screen.
I've tried swapping RAM multiple times, but I don't think that's it - I can boot 10.2, 10.3, 10.4, and 10.5 just fine, as well as my one working copy of 9.2.2.
Anyone have a confirmed-good iMac G4 800 MHz that they would be willing to throw a restore image on, confirm it works, maybe run OS updates on, then re-image for me?
