Raw 4 MB BIN dump named after the P8H61-M LX3 board, an Intel H61 desktop board model from ASUS, though the name gives no version or revision. The size corresponds to a 32 Mbit SPI flash chip. Technicians write such images with a CH341A or similar programmer to recover boards that no longer post. Back up the existing chip contents first, since serial and MAC data may be stored there, confirm the board model on the PCB and make sure the chip capacity matches the 4 MB image.
