BIOS image for the ASUS X409JA notebook, described as tested and working, packed in a 5.10 MB RAR archive. The name gives no board revision, so check the motherboard label against the dump before flashing. Technicians write such files to the SPI flash chip with an external programmer to recover a laptop that fails to post after a bad update or corrupted firmware. Save the original chip contents before writing, and confirm the image size corresponds to the capacity of the chip fitted.
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.
