BIOS backup dump for the Lenovo board NM-D474, an LCFC design, as a 16 MB binary image. Being described only as a backup, the name does not say which laptop model, BIOS version or ME state it holds. Such a dump is normally written to the SPI flash chip with a programmer such as a CH341A to recover a board with corrupted firmware. The 16 MB size must match the capacity of the chip on your board, and you should save a copy of your original chip contents first, since serial number and other unique data may differ.
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 →
