After the test POST-code is recorded in the Manufacturing Test Port, the procedure for testing the corresponding equipment begins. If the testing procedure fails in the Manufacturing Test Port, the POST code of the last procedure remains (which caused the error). If you know the POST code of the last procedure, you can identify the device that caused the error.
Reading POST codes can be done in several ways. If your motherboard has a built-in indicator of POST-codes, you can learn information about the POST-code of the last procedure from it. The POST-code of the last procedure performed on some systems may be displayed on the monitor screen during the POST procedure. A special expansion card can be used to read POST codes. Since the BIOS is produced by several manufacturers, respectively, each BIOS of an individual manufacturer has its own table of POST codes.
