Raw BIOS image of exactly 1.00 MB in BIN format, named with the number 411820210001-r and a cnf ok note that seems to indicate a confirmed working dump. The name gives no brand or model, so identify the target board before using it. A 1 MB image corresponds to an 8 Mbit SPI flash chip and can be written directly with a programmer such as a CH341A. Read and keep the original chip contents first, and only write it when the chip capacity is 8 Mbit and the board markings match.
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 @freeschematicdiagram. 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 →
