 @param[in, out]    BiosCommDataBuffer  On entry, pointer to BIOS communication data buffer.
                                        On exit, points to updated BIOS communication data buffer.

 @retval            EFI_UNSUPPORTED     Returns unsupported by default.
 @retval            EFI_MEDIA_CHANGED   Alter the Configuration Parameter or hook code.
