BIOS package for the Lenovo Z51-70 built on Compal motherboard LA-C282P, compressed as a 3.63 MB zip. Compal uses the LA-xxxxP pattern for its laptop boards, and this one also appears under other Lenovo models, so the PCB revision matters. Extract the archive and check that the image size matches the SPI flash chip before programming. Read out and keep the original firmware first, since it holds the serial and system-specific data.
