BIOS image for Compal board LA-E891P with the Intel Management Engine region cleared, supplied as a 4.93 MB ZIP. A cleaned ME region lets the firmware rebuild ME data on first boot, which helps with boards that power on and shut off or show ME errors. Compal LA-xxxxP boards are used in many branded laptops, Acer among them. Flash the image with an SPI programmer after backing up the existing chip. Then confirm the board number on the PCB and check that the image size matches the flash chip.
