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 01x Undetermined problem errors. 02x Power supply errors. 1xx System board errors. 101 System board error - Interrupt failure. 102 System board error - Timer failure. 103 System board error - Timer interrupt failure. 104 System board error - Protected mode failure. 105 System board error - Last 8042 command not accepted. 106 System board error - Converting logic test. 107 System board error - Hot NMI test. 108 System board error - Timer bus test. 109 Direct memory access test error. 121 Unexpected hardware interrupts occurred. 131 Cassette wrap test failed. 152 161 System Options Error-(Run SETUP) [Battery failure]. 162 System options not set correctly-(Run SETUP). 163 Time and date not set-(Run SETUP). 164 Memory size error-(Run SETUP). 199 User-indicated configuration not correct. 2xx Memory (RAM) errors. 201 Memory test failed. 202 Memory address error. 203 Memory address error. 3xx Keyboard errors. 301 Keyboard did not respond to software reset correctly, or a stuck key failure was detected.
