BIOS dump in zip form for the ASUS S4300U / X430UN, board revision 2.1, with the Management Engine region reported as cleaned. A clean ME region lets the Intel firmware reinitialise, which helps cure boot loops or long start-up delays after flashing. The image is written to the SPI flash with a programmer once the original chip is read and saved. Confirm the board revision printed on the PCB is 2.1, and make sure the file size matches the chip capacity before writing.
