BIOS archive for a board identified only as MT55 CHY, packed as an 8.61 MB RAR. The name gives no brand, revision or version, so the target hardware should be confirmed against markings on the motherboard before relying on it. A file of this kind is generally flashed to the SPI chip with a programmer to recover a board with damaged firmware. Always read and back up the original chip first, and ensure the image size matches the flash capacity, otherwise it will not fit.
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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
