BIOS image for the ASUS TUF X470-PLUS GAMING desktop motherboard, stored in a RAR archive of about 28.6 MB and labelled as fully working. Boards of this kind keep firmware on an SPI flash chip that can be programmed out of circuit or with a clip when the board will not post after a failed update. Before writing, read and keep a copy of the current chip contents, and confirm that the image size matches the chip capacity, since a mismatched file will not fit or boot correctly.
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 @biosarchive. Enginerys does not host this file.
