Appendix A. Error Codes
This section identifies the POST error codes and beep error codes for the PC 100 and PC 300.
POST Error Codes
POST error messages appear when POST finds problems with the hardware during startup, or when a
change in the hardware configuration is found. POST error messages are 3-, 4-, 5-, 8-, or 12-character
alphanumeric messages. An
x in an error message can represent any number.
