  41                                     For example, system error may be not supported to process and Platform should have mechanism to reset system to manufacture mode.
  42                                     Another, if system and user variables are wanted to be distinguished to process, the interface must be called after EndOfDxe.
  43   @retval EFI_OUT_OF_RESOURCES      Not enough resource to process the error.
  44   @retval EFI_INVALID_PARAMETER     The specified Flag or Type is an invalid value.
