Listing of IBM PC Diagnostic Error Codes
Jerry Schneider Capital PC User Group Washington, DC
All personal computer error codes for the Power On Self Test, General Diagnostics, and Advanced Diagnostics consist of a device number followed by two digits other than 00. (The device number plus 00 indicates successful completion of the test.)
This list is a compilation from various sources, including USENET's Info-IBMPC Digest, IBM Technical Reference Manuals, and IBM Hardware, Maintenance and Service manuals.
Code Description
