BIOS image for the Sony VAIO SVF154B1EL on Quanta board DA0HKBMB6D0, revision D, described in the name as working. Quanta uses the DA0 prefix pattern for its motherboard numbers, and the revision letter must match the board. The dump is written to the SPI flash with an external programmer such as a CH341A when the laptop has a corrupted BIOS. Read and keep a copy of the original chip first, and confirm the image size equals the chip capacity before writing, inside the 6.29 MB RAR.
