My G4 behaved exactly the same way the first time I tried to install X: I got the "You must restart" screens, the freezes, etc. and I did all the stuff you've done to try to fix it with no effect. I finally tried pulling the RAM chips and putting them back in one by one. Turned out one of the three RAM sticks was bad, at least as far as OS-X was concerned (it always worked fine in 9), because with that one chip removed OS-X installed and ran fine ever after. I found out which RAM chip was "bad" by trial and error. By the way I had bought name-brand RAM from a reputable dealer, too-- OS-X is just incredibly fussy about the quality of the chips. Apparently if there's the slightest flaw in them, X won't install or run.

Try pulling all your RAM except for the bare minimum. Retry the installer.

We're trying to install OS X (10.3 CD) for the first time on a 300MHz blue&white G3 tower (which, by the way, doesn't seem to appear as an option in Apple's specs).

80GB Maxtor drive erased fine, and the OS 9.2.1 CD installed fine. The 9.2.2 update didn't work properly in Software Update, but ran fine from the desktop after the reboot.

So OS 9 seems stable on this machine as would be expected.

BUT, OS X has been a nightmare. The first few times trying to install were greeted with a variety of behaviors:

- a white-lettering-on-black rectangle (in 4 languages) saying only that the Mac needs to be restarted

- OS X install failed with no error detail

- installer log revealed an error: "root:bootstrap_lookup(): unknown error code

- two other error messages (system rebooted itself before we could write them down) after a mostly successful install - this happened during optimization (log indicated that install was successful, but optimization failed)

At two early reboots, the system started to come up in OS X, then dropped into a full-screen console login screen.

Finally, after several reboots, the system mysteriously seemed to work for awhile, but then started to get the white-lettering-on-black message again. his now seems to be a persistent behavior, though we can still reboot into OS 9 and all still seems fine.

Any ideas? We've repaired disk several times. We zapped PRAM, we unplugged all peripjerals. The OS 10.3 CD boots consistently and seems to run fine, just something about the ability to get OS X installed successfully on the hard disk. Is this model inherently flawed or incompatible in some way?

Thanks,
Gordon
