ASUS VivoBook 15 X540UV firmware image for board revision 2.0, stored as a 5.55 MB RAR. Model and revision come straight from the name; no flash chip type is given, so check the marking on the SPI device before choosing a programmer profile. Typical use is recovery of an X540UV that powers on without display or loops after a bad BIOS update. Confirm the PCB reads Rev 2.0, read and keep the original contents, and only write once the binary size equals the chip capacity.
