Two of our machines here have little LEDs on their CPU boards. The first thing I do if one of them dies is to open the front of the machine and see is going on. Very useful when running in single user mode and you are not getting any replies from the console. Another of our machines has a number of lights on the front which report disk activity. You can tell what stage of the boot procedure it is at (before anything appears on the console) by the pattern of the lights. If something goes wrong it saves a lot of time knowing at what stage it went wrong. Bob Gray. Dept. of Computer Science. Heriot-Watt University.
