// Description:
// OEM Rom ID Check protocol is for Flash utility to send customer defined specific ROM ID for BIOS to ID version
// checking uses.
//
// BIOS should provide inserted ROM file's specific ROM ID location and then check it, when ID is given by Flash
// Utility after OFBD_EXT_TBL_END.
//
// Moreover, Flash utility will have corresponding action, either stop flashing BIOS.
