A small problem... After install the machine reboots automatically. We are not given an opportunity to stop the reboot. In fact, we are not even told a reboot is going to happen. Maybe the installer needs a step that confirms the reboot with a Yes/No prompt? The issue is aggravated by OpenFirmware behavior. Each command I issue at the OF prompt results in a "corrupt disk" message. I can't even eject the cd. OF tries to load the OS for each command I issue. Jeff
