Firmware archive for the Lenovo IdeaPad S415 notebook, a Compal design with project code ZAUSA, linked to board number LA-A331P. Compal LA-xxxxP numbers are printed on the motherboard and should match before using the dump. The image is used to restore a corrupted BIOS on the SPI flash chip with an external programmer when the laptop does not show a picture. Check that the image size matches the chip capacity and back up the existing chip contents before writing.
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.
