BIOS dump for an X1404ZA mainboard, revision R2.0, marked as working, provided as a 16 MB file with no extension. The name follows ASUS-style model naming, though no brand field confirms it. A 16 MB image fits a 128 Mbit SPI flash chip, written with a programmer such as a CH341A or a more capable unit for newer chips. Rename it to .bin if your software requires it, back up the original chip before writing, and check that the board revision on the PCB matches R2.0.
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 @schematiclaptopramkushwaha. 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 →
