Zipped BIN firmware dump for the Lenovo IdeaPad S400 built on Compal board LA-8951P, with no revision or version given in the name. The LA-xxxxP pattern is Compal's numbering, so matching it on the PCB is the reliable check. Technicians use the image to reprogram the SPI BIOS chip with a programmer such as CH341A after corruption or a failed update. Extract the archive, confirm the file size matches the flash chip capacity, and read and store the original chip contents before writing the replacement.
