BIOS firmware for the Dell Inspiron 3521 on Compal motherboard LA-9101P, packed as a RAR archive. Compal manufactures this board for Dell, which is why it uses the LA-xxxxP numbering. Technicians flash such an image to the SPI chip with a programmer to recover a machine with no display, endless restarts or corrupted firmware. Dell dumps also contain service tag and system data, so read and save the original chip first, confirm the board number matches, and verify the image size equals the flash chip capacity.
