BIOS image for the ASUS X540UBR laptop, board revision 2.0, marked in the name as working, inside a 5.95 MB RAR. A tested dump like this is used to recover a board with corrupted firmware by writing it to the SPI flash chip with an external programmer such as a CH341A or RT809H. Read and keep the original chip contents before programming, since serial number and other board-specific data may differ. Confirm that the image size matches the flash chip capacity and that the PCB revision is 2.0.
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.
