BIOS dump for the ASUS S551 series, model S551LN, intended for main board revision 2.2. The RAR archive is about 3.34 MB and contains the image to be written to the flash chip with an external programmer. Repairers use such files to bring back boards with damaged firmware or after replacing the BIOS chip. Confirm that the revision printed on the PCB reads 2.2, check the image size against the chip, and read out the original before overwriting anything so it can be restored if needed.
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.
