BIOS firmware archive for the Lenovo S415 laptop, supplied as a 1.82 MB RAR file. The name states only the model, with no board number, revision or firmware version, so open the archive to check its contents first. A dump like this is used when a machine shows no display or loops on power-up because of corrupted firmware, and it is written to the SPI flash chip with an external programmer. Read and keep the original chip contents first, and confirm the image size matches the flash capacity.
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 @biosbigarchives. Enginerys does not host this file.

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 →
