BIOS archive for the ASUS X540SA at board revision 2.0, 3.71 MB as RAR. A separate revision 2.1 image exists, so compare the revision printed on the PCB before choosing this one. Extract the file and confirm the image size equals the SPI chip capacity. Use an external programmer to read and save the original contents first, then write this image to recover a board with corrupted firmware or a no-boot fault.
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.
