BIOS for the ASUS S551LB laptop, board revision 2.1, in the variant fitted with an NVIDIA GeForce 740M graphics chip. The RAR archive is 6.76 MB. A dump like this restores firmware when an update failed or the chip got corrupted, and is written with an SPI programmer. Because the name specifies the discrete GPU variant, check that your board carries the same graphics option and revision, back up the original flash before writing, and confirm the file size matches the chip capacity.
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.
