ASUS X450LD BIOS at revision 2.1, an 8 MB image described as the ME region file, meaning it includes the Intel Management Engine region. The size suits a 64 Mbit SPI chip, and the revision should match the one printed on the PCB. Technicians flash such an image when ME corruption causes boot faults or a no-display condition.
