Dell firmware image for Compal-built motherboard LA-L591P, 32 MB in size and supplied without a file extension; the name describes it as unlocked with a cleaned Management Engine region. The LA- prefix is Compal's numbering pattern, used on many Dell Latitude and Inspiron boards. A cleaned ME image is used to reprogram the SPI flash when a board fails to start because of firmware corruption. Dump and keep the original chip before writing, check the LA-L591P label on the PCB, and make sure the chip capacity matches the 32 MB image.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
