BIOS dump for the Lenovo G580 built on the Compal LA-7982P mainboard, compressed into a 3.07 MB 7z archive. Compal names its laptop boards with the LA-xxxxP pattern, and that code is printed on the PCB, so check it before flashing. A dump like this is written to the SPI flash chip with a programmer such as a CH341A to recover a corrupted BIOS or a board that will not start. Read and save the original chip contents first, and confirm that the image size matches the chip capacity, or it will not fit.
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.
