Compressed BIOS package for the ASUS S551LN ultrabook, about 3.26 MB as a ZIP file. No version or board revision is given in the name, so check the extracted image and any notes inside. ASUS boards of this generation normally use a single SPI chip, and such a dump is written with a programmer when the laptop has no display or loops on power. Compare the extracted image with the flash capacity, back up the original contents, and verify the write before reassembly.
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.
