BIOS file for the Lenovo N580 laptop on Compal board LA-7982P, packed as a RAR archive of about 3 MB. Compal names its motherboards with an LA- prefix and a four-digit project number, and the code is printed on the PCB near the memory or edge of the board. The image is meant for repairing corrupted firmware by writing the SPI flash chip with an external programmer. Check that the board number matches, save a backup of the original chip, and confirm the dump size fits the installed flash.
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.
