Compal LA-E891P BIOS image with the Management Engine region cleared, packed in a 4.76 MB RAR archive. Compal LA-numbered boards are used in many brand-name notebooks, so confirm the number printed on the PCB. A cleared ME region removes stored machine-specific ME data, which helps when a board fails to boot or shuts down after a few seconds due to ME corruption. Write it to the SPI chip with a programmer, but back up the original first, since serial and system data may need transferring.
