ASUS X540SA BIOS for board revision 2.1, packed in a 3.78 MB ZIP archive. The revision is printed on the mainboard and should match before flashing, since a revision 2.0 image exists separately. Extract the archive and confirm the image size equals the SPI flash capacity. Technicians write such files with a programmer to recover a corrupt BIOS, but should always read and store the original chip first so the board can be restored if needed.
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.
