Firmware archive for the Lenovo B40-80 laptop, a 3.60 MB RAR. The name gives only the model, with no board number, chip type or version, so check the contents and the PCB label before relying on it. A BIOS image like this is normally flashed to the SPI chip with a hardware programmer to recover a board left dead by a failed update. Read and save the existing chip before erasing it, and confirm that the image size matches the chip capacity, or it will not fit.

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 →
