BIOS .bin image for the Lenovo IdeaPad S400 on Compal board LA-8951P, packed into a 3.24 MB RAR. It is used to reflash the board's SPI chip with an external programmer, for example when a failed update leaves the laptop unbootable. Because other dumps of the same board are available, comparing them can help find a clean one. Read and save the existing chip contents first, and confirm the board number on the PCB matches. Check that the binary size equals the chip's capacity.
