Robert,

I had the exact same problem during the install. The only way I could find to complete the install was to remove the RAM from the upper slot. No amount of PRAM zapping, video driver deletion, permissions repairing, or even reformatting the destination drive would change the 'color-meltdown' abortive install process. Removing the top-slot RAM worked. BTW, running an exhaustive RAM check utility from OS 9 finds NO problem with the memory module, and I never saw a similar problem in any version of OS X from 10.1 up to 10.2.6.

The good news is you can reinstall the RAM module once you've got a working Panther OS. Everything works as it should, with one major exception: trying to repair permissions using Disk Utility. Since installing Panther on this machine, any attempt to repair permissions from the boot disk will cause the color-meltdown every time. The only other time I've gotten the meltdown event is during a large (> 200MB) network copy from the Lombard to my G4. Smaller copies seem OK. I'm not sure what the problem is, but it seems the video RAM gets corrupted during these operations, and locks the system up tight (no cursor movement or response to keyboard) - the three-finger salute is the only thing that will get you out of this condition.

It seems clear (to me at least) that this is a (OS) software problem/conflict. Hope someone eventually figures this out, or Apple supplies a fix. Being as it only happens when more than the supported amount of RAM (256MB) is installed, I doubt Apple is too concerned with this. This problem only began happening with the 10.2.8 version of the OS, and has persisted through the 10.3.2 revision. Feel free to post any ideas or suggestions you may discover about this; I've scoured the 'net, and have yet to find a solution. Good luck. . .

Rick


I have a lombard with 512 RAM and 40GB HD. currently running the latest version of 10.2. When i try to install Panther it gets most of the way through the install and then the screen goes "funky" as if both the vertical and horizontal hold both go at the same time. i tried an archive and install, completely wiping the HD with norton and installing nothing but Panther, but it refuses to install. i got the same problem with the ill fated 10.2.something upgrade that i was dumb enough to install right when it was new.

Any ideas or suggestions would be greatly appreciated
