Firmware archive for the ASUS VivoBook X540UP containing both a BIOS image and EC firmware for an ITE embedded controller. No board revision is stated, so check that your motherboard matches the X540UP before flashing. The BIOS is written to the SPI flash chip with a programmer, while the ITE EC image handles power sequencing, battery charging and keyboard functions and may need a separate flashing tool. Back up original contents before writing, and verify each image size against the corresponding chip.
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.
