BIOS dump, 16 MB, for Lenovo motherboard NM-C781, an LCFC board number; LCFC is the Lenovo-owned ODM that uses the NM- prefix. The name gives no laptop model, BIOS version or ME state, so treat it as an untested full SPI image. A 16 MB file matches a 128 Mbit flash chip. Back up the original firmware with a programmer first, check the NM-C781 marking on the PCB, and expect to restore serial number and machine type data after 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 @cidschematicandboardviewofficial. 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 →
