Compressed firmware dump named top, likely the companion of a bottom image from a board that uses two flash chips or chips on both sides. The name states no device, board number or chip size, so it is of little use without knowing its origin. When reflashing, write each image only to its matching chip, verify the unpacked file size against the chip capacity, and keep a backup of the original contents. An unknown dump written to the wrong board can leave it unable to start.
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 @vinafix_bios. Enginerys does not host this file.
