Firmware archive for the ASUS X430UN motherboard, revision 2.1, considerably larger than a single image at about 17 MB, so it likely holds several files; check the contents before use. Such dumps are flashed to the SPI chip with an external programmer when a board fails to start or loses its firmware. Match the revision printed on your PCB to 2.1, read the existing chip contents for backup, and choose the image whose size matches the flash capacity, since an oversized file will not fit.
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.
