BIOS firmware for the Lenovo G455 laptop, AMD variant, motherboard LA-5971P, packed as a 1.13 MB zip. The compressed archive probably holds a 2 MB SPI image, though the name gives no version. LA-5971P follows the Compal board numbering, so the board was designed by Compal for Lenovo. A technician would use it to reprogram a corrupted flash chip with an external programmer. Dump and save the original chip first, confirm the board number on the PCB, and check that the extracted image size equals the chip capacity.
