BIOS POST Codes

The POST card is an expansion board that has its own digital indicator and outputs the initialization codes of the motherboard to it. With the latest code output, you can determine which component has a malfunction. These codes depend on the BIOS manufacturer of the motherboard. In the absence of errors and normal passing of the test, POST gives to its indicator a value that does not change during the operation of the computer, depending on the BIOS version, for example, on most cards, at the end of the initialization, the code FF is issued.
