I'm running this in parallel to my GigE thread about OS installs, but thought I'd post this problem separately to see if anyone has any ideas. Whenever I try to run the 10.0.3 install disk, I get the below error during booting. I'm using an original 10.0.3 pressed install disk. The same error has appeared on two different system configurations: 1. Sawtooth 400mhz w/2gb RAM, Radeon 8500 2. GigE dual 500mhz, 2gb RAM, GEForce 2MX Twin-View. I've run AHT(short test) on this computer, and everything passed. I've also successfully installed OS 9.2.2, Panther, and Leopard(using LeopardAssist) on this computer. It runs fine on Tiger the Tiger install that was done on the Sawtooth. I've done the standard stuff-PMU reset, PRAM reset, etc. I updated the firmware to the most current version-4.2.8. Does anyone have any ideas about what could be going on here?
