Could have been a file corruption, I had one somewhere when Tiger installed for the first time. Again, after installing the computer would have a kernel panic on every restart or shutdown. The solution was to do a Archive and Install over the existing 10.4 tiger installation, that fixed it rather painlessly. The traditional hardware method limited the problem down to the Apple usb keyboard.. Oddly enough most of the time the computer would not panic if the keyboard was substituted for the original mini G4 / imac keyboard. So, something was messed up there, but it is all fixed now minus the DVD player issue. Note that prior to this I was running on a upgraded system folder that had been around problem free since Mac os 10.0. Considering the changes made since then it is not out of the question for something like that to happen over that much time. Daniel J.
