Lenovo BIOS dump in raw BIN format, 16 MB in size, which corresponds to a 128 Mbit SPI flash chip. The name describes it only as a new Lenovo BIOS and gives no model or board number, so its source machine cannot be confirmed from the name. Open it in UEFITool or a hex editor to check the version strings before use. Write it with a programmer only after saving the original chip contents, and confirm the target flash is 16 MB and the board matches.
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 @technodev_bios. Enginerys does not host this file.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
