Working BIOS image for the ASUS X1403ZA laptop with board revision R2.1, packaged as a 24.6 MB RAR archive and labelled as fully functional. Such dumps are flashed onto the SPI BIOS chip with a hardware programmer like a CH341A to revive a board that will not power on or show an image after a failed update. Before writing, back up the original chip, because it holds serial and system data, and check that the image size matches the flash capacity. The board revision on the PCB should also match R2.1.
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 →
