Raw 16 MB BIOS binary whose name points to an LA-C871 board, a Compal-style code, with 20G2 appended as an extra tag the name does not explain. The size matches a 128 Mbit SPI flash chip, so the image can be written directly with a programmer such as a CH341A or RT809. Confirm that the board marking and chip capacity match before writing, and always read and save the existing contents first so the original serial data and settings can be recovered if needed.
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 @efibios. 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 →
