POST codes correspond directly to tests that are taking place by the POST. When a POST card stops at a specific POST code during the boot process, that specific code can be referenced to a list of possible POST codes generated by your specific BIOS and can help determine what the problem is.
Important: A POST code is not the same as a system error code, a STOP code, a Device Manager error code, or an HTTP status code (sometimes referred to as a browser error code or an Internet error code).
Some POST codes share code numbers with one or more of these other types of error codes but they are different errors with completely different meanings.
