BIOS archive for a Lenovo 330S board marked 330S-KBL-MB-V07, revision MP, which usually means the mass-production release. KBL refers to the Kaby Lake platform. The ZIP is about 4.80 MB and needs extracting to get the image. Write it with a flash programmer to revive a board with corrupt firmware. Check that the PCB marking matches, dump and keep the existing chip contents first, and make sure the image size equals the flash chip capacity.
