BIOS archive for the ASUS X401A notebook, mainboard revision 3.0. It is meant for reflashing the system SPI chip when the laptop powers on with no display, keeps restarting, or was left corrupted by a failed update. Write it with an external programmer such as a CH341A, either with a clip or with the chip removed. Confirm that the PCB revision reads 3.0, save the original chip contents before erasing, and check that the image size corresponds exactly to the capacity of the installed flash chip.

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 →
