UEFI BIOS image for a board named A14HV0X, revision 4.0, in a RAR of about 2.65 MB. The maker and device are not given, so confirm the board marking matches before flashing. Being marked UEFI distinguishes it from a separate legacy image for the same revision. Technicians write it to the SPI flash with an external programmer to recover a dead or bricked board. Read and keep the original contents first, and make sure the image size equals the chip capacity.
