For their PS/2 systems, IBM used a system of diagnostic codes to diagnose trouble spots in a given computer.  The problem was, these diagnostic codes were never really documented all that well.  The codes that I am presenting here are from documents I have read through, found on the web, found in old books, documents and technical papers.  As a computer technician, I rely on documentation to guide me through these types of messages.  Therefore, I hope to provide this to all those other technicians out there who get the opportunity to work on one of these.  And, yes, people still use them and some refuse to give them up.

The method for reading these codes is pretty straight forward.  The first part of the error code indicates the device that is causing the trouble.  The second part gives the meaning of the error.  You can think of the first part as the test code and the second part as the fault code.  A fault code of 00 indicates that no problem was found.  Thus 200 means the system memory was tested.   The 00 means that no fault was found.  201 would mean a memory error.   202 would mean memory address error; lines 00-15. 

This page is rather extensive and will be updated on a regular basis.  Like all the other codes out there.  If you know of any error codes that I am displaying incorrectly or that aren't here.  Let me know and I'll get it corrected as soon as I can.

Thanks to Mike Rose for erors 129 and 229!
