BIOS firmware archive for the ASUS X540SA laptop, motherboard revision 2.1, packed as a 3.78 MB ZIP. The name gives no version number or ME status, so open the archive and check what it holds before use. Images like this are typically written to the board's SPI flash with a programmer such as a CH341A when the machine no longer posts or a bad update has corrupted the BIOS. Match the revision printed on the PCB, back up the existing chip, and confirm that the dump size fits the flash part fitted on the board.
