Compressed BIOS firmware for the Lenovo G580 laptop, with 20157 most likely being the Lenovo machine type number. The 2.82 MB RAR probably holds a flash dump, and the (2) suffix suggests a second copy of a similar archive. Extract it to check file sizes before use. Such images are written to the SPI chip with a programmer to recover a board with no display. Identify the mainboard and revision on the PCB, since G580 units used several board designs, and save the original chip first.
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.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
