Firmware dump for a Lenovo motherboard identified as I470MS1, revision 1.0, compressed in a 13.3 MB RAR. The name does not state the laptop model, so match the board marking on the PCB before using the image. Images like this are flashed to the BIOS SPI chip with a hardware programmer to bring back a board that will not power on, shows no display or fails after a bad update. Check the flash chip capacity against the extracted file size. Always read and keep the original contents so that serial and system data can be restored.
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.
