Archive of 85.1 KB containing BIOS or firmware for the Dell Latitude E5550 built on Compal board LA-A911P, tagged CD3301. Its small size means the zip may hold a partial or compressed image, so verify the contents before flashing. Compal is the ODM signalled by the LA-number pattern. Repair use is usually reprogramming the SPI flash with an external programmer on a unit that fails to start. Save the original chip first, check the PCB number, and confirm the image matches the chip capacity.
