BIOS package for the ASUS X540SA laptop motherboard at revision 2.1, labelled as fully working. At 40.4 MB the RAR is large for a single image and probably contains multiple files or tools, so review the contents before use. Technicians write the correct image to the SPI flash with a hardware programmer to revive a board that will not post. Check the model and revision on the PCB, back up the original chip contents, and confirm the file size matches the flash chip capacity before programming.
