BIOS image named r08uj17ww in BIN format, zipped to 4.49 MB. The name looks like a Lenovo style BIOS version code, but it gives no laptop model or board number, so you will need to confirm which machine it belongs to before use. A raw BIN image is written directly to the SPI flash chip with a programmer to revive a board that powers on but does not boot. Read and keep the original chip contents, check that the file size equals the chip capacity and match the board.
