BIOS firmware for the Lenovo IdeaPad S400 built on Compal board LA-8951P, supplied as a 3.30 MB ZIP. Compal labels its laptop motherboards with the LA-xxxxP pattern, and the code is printed on the PCB near the edge. Use the dump to recover a corrupted or password-locked board by flashing the SPI chip with an external programmer. Read and keep a backup of the original chip first, check that the image size equals the flash capacity, and confirm the board number before writing so the dump suits the hardware.
