BIOS archive for the ASUS X451CA mainboard at revision 2.1, compressed to 3.42 MB in RAR. ASUS prints the board model and revision on the PCB, so check both before writing this image. Use it to reprogram the SPI flash when the notebook powers up without picture or stops after an interrupted update. Open the archive and confirm the binary size matches the flash chip capacity. Read the original chip with a programmer first so any system data can be restored if needed.
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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
