BIOS firmware archive tied to the ASUS X1404ZA, board revision R3.0, with the ASUS X1504ZA also named. That suggests the two models share this platform, but the name does not confirm full compatibility. The 7.30 MB RAR holds a dump meant to be written to the SPI flash chip with a hardware programmer such as a CH341A. Read and save the original chip contents before erasing it. Make sure the image size matches the chip capacity, and confirm the model and revision on the board.

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 →
