Firmware dump for Compal board LA-C671P, labelled C20-00, provided as an 8.33 MB ZIP archive. The laptop brand and model are not given; C20-00 is probably the project or model code but is not explained. LA-xxxx numbering is Compal's mainboard scheme, used across many laptop brands. Extract the image and program the SPI BIOS chip with a programmer. Match the board number on the PCB, save a backup of the original chip, and make sure the image size equals the chip capacity.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
