BIOS dump for the Dell Latitude E7440 on Compal board LA-9591P, with the Management Engine region cleared and marked as working. A clean ME region is often used after replacing a chip or fixing ME firmware errors and slow-start faults. The 6.70 MB ZIP should be written with an SPI programmer such as CH341A or RT809. Read and save the original chip contents first, as they contain the service tag and system data, and confirm the image size fits the flash chips.
