BIOS dump for the ASUS X540UBR board revision 2.0, intended for units with a 7th generation Intel CPU, packed in a 13.7 MB RAR archive. The name states an 8MB image and describes it as fully working. Extract it and write it to the SPI flash with a programmer such as a CH341A after reading and saving the original chip contents. The image must match the 8MB chip capacity. Since the same model also exists with 8th generation processors using different firmware, confirm the CPU generation and board revision before flashing.
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.
