Firmware dump for the Lenovo B40-30 laptop using the Compal LA-B102P mainboard, packaged in a 2.53 MB zip. The name states no revision or BIOS version, so inspect the archive before relying on it. Compal uses the LA-prefix numbering seen here for boards made for Lenovo and other brands. A technician writes such an image to the SPI chip with a programmer to fix no-boot or no-display faults. Read the original chip first, keep the backup, and confirm the image size and the board marking match.
