POST error codes

Each time you turn the computer on, it performs a series of tests to check that the system is operating correctly and that certain options are set. This series of tests is called the Power-OnSelf-Test, or POST. POST does the following:

•Checks some basic system-board operations

•Checks that the memory is working correctly

•Starts video operations

•Verifies that the boot drive is working
