ASUS X451CA firmware image for mainboard revision 2.1, supplied as a 4.85 MB RAR and marked as a working, fully tested BIOS. Revision 2.1 boards may differ from earlier ones, so match the revision silkscreened on the PCB before use. The extracted image is programmed onto the SPI flash chip with a tool such as a CH341A or RT809 to cure no-boot and black-screen faults caused by damaged firmware. Always read and keep a copy of the original contents, and confirm the dump size equals the chip size.
