Lenovo BIOS image of 16 MB in raw BIN form, associated with board NM-D471, a number following the LCFC numbering used for Lenovo-designed laptop motherboards. The name itself says only new 16 MB, giving no model, version or region-clean status. The size suits a 128 Mbit SPI flash chip, which a CH341A-class or similar programmer can write directly. Check that the PCB silkscreen reads NM-D471 and that the chip on the board really is 16 MB, and save a backup of the existing contents, including serial and key data, before writing.
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 @schematiclaptopramkushwaha. 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 →
