Method for testing a processor module in a computer system

摘要: A reliable diagnostic system for running power-up diagnostics, displaying results, and retaining a power status history. First, method of testing processor module in computer is provided. including serial port reads test instructions from PROM line controller through the by way bus response to reset instructions. Next, means connecting control modules Accordingly, backplane connectors are provide wide signal conducting elements having multiple solder connection points backplane. The electrically connected each these elements. Also, an apparatus indicating failures console panel provided comprising LED's visible user, LED corresponding particular module. Any which remains lit indicates failure Finally, maintaining Status indicators various environmental conditions supplied. When any indicator changes value, stored non-volatile memory. In event shutdown, memory then retains history representing prior shutdown.
