BIOS dump for the BM5918 board revision 1.0, carrying firmware version CQCN34WW and described as fully working. The WW-ending version string follows the style Lenovo uses for its BIOS releases, though the name does not state a model. Write it to the board's SPI flash with an external programmer to recover a bricked or non-booting system. Verify that the board marking matches, back up the original chip first, and ensure the image size corresponds to the chip capacity.
