Clean-ME BIOS image set for the Dell Latitude 5470, motherboard Compal LA-C831P, described in the name as checked and working. A Management Engine region in factory state helps clear ME-related boot faults and long power-on delays after board repairs. Program it onto the SPI flash with a hardware programmer such as a CH341A or RT809H. Back up the existing chip contents first to keep the service tag and MAC data, and confirm the LA-C831P marking on the board.
