Asus S551LB BIOS for mainboard revision 2.2, supplied as a 3.36 MB ZIP archive. The name gives no BIOS version or flash chip, so examine the contents to see whether it is a full SPI dump or a vendor capsule. Technicians use such images to recover units stuck on black screen after a failed update, writing the dump directly to the chip with a programmer. Check that the board revision printed on the PCB is 2.2, save the original chip contents before erasing, and match the image size to the flash 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.
