BIOS archive for the Asus S551LB, with 2.1 most likely referring to the main board revision, packed as a 3.33 MB RAR. The image serves to restore the firmware on this laptop when it is bricked or shows no display after a failed update. Asus prints the board model and revision on the motherboard, so confirm they match before flashing. Use an external SPI programmer, save the original chip read first because it holds unique data, and check that the file size corresponds to the flash chip fitted.
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.
