BIOS image shared by the ASUS X1502ZA and X1403ZA laptops, board revision 2.1, supplied as a 7.41 MB RAR archive. These models use closely related mainboards, which is why one dump covers both. A technician programs this image into the SPI flash with an external programmer to recover a dead or bricked board. Back up the original chip first to keep serial and licence data, confirm the PCB reads R2.1, and ensure the image size equals the flash chip capacity.
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 →
