Raw BIOS ROM image for a Lenovo G455 laptop in its AMD version, built on the LA-5971P motherboard. The 2.00 MB size fits a 16 Mbit SPI flash chip, so it can be written directly with a programmer such as a CH341A or RT809. LA-xxxxP numbers follow the Compal board-numbering scheme, Compal being the ODM behind this design. Before flashing, check that LA-5971P is printed on the PCB, read and keep the original chip contents, and verify the target chip capacity really is 2 MB so the image fits.
