ASUS X556UV BIOS dump for mainboard revision 3.1, with the Intel Management Engine region cleaned, as the CelanME tag indicates (a misspelling of clean ME). A cleaned ME region resets stored ME configuration, which often helps when a reflashed board shuts down after a short time. Program it with an SPI programmer after saving the original chip read, since that backup holds the serial number and MAC data. Confirm the revision on the PCB is 3.1 and that the image size matches the flash chip.
