Firmware dump for the ASUS X451CA laptop, listed without a file extension and only 128 KB in size. That small capacity is typical of an EC (embedded controller) or keyboard controller firmware chip rather than the main BIOS image, though the name does not say which, so check it before use. Such a file is written with a programmer to the matching small flash chip. Back up the original part first and verify that the chip capacity equals the dump size.
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.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
