Firmware archive for the Lenovo G580 notebook, packed as a 2.92 MB RAR. The name gives no board number, revision or BIOS version, so inspect the contents before use. The G580 was built on more than one mainboard design, so read the board number printed on the PCB and make sure it matches whatever the archive turns out to target. Typical use is reflashing the SPI BIOS chip with a hardware programmer after a failed update. Keep a backup of the original dump in case the image is wrong.
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.
