Second copy of a Lenovo IdeaPad S340 BIOS binary, also 16.0 MB and matching a 128 Mbit SPI flash. The name states no board number, platform or version, so it is unknown whether it matches the other S340 dump or differs from it; a checksum comparison will tell. Because the S340 was built on both Intel and AMD platforms, check the motherboard markings first. Before programming, back up the existing chip, confirm that its capacity matches the image, and verify the result after writing to avoid a no-boot condition.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosfilebins. Enginerys does not host this file.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
