Zip archive containing a binary named only for its size, 2 MB, with no brand, model or board number given. A 2 MB image fits a 16 Mbit SPI chip, a capacity common for EC firmware or older system BIOS. Since the source is unknown, open it in a hex editor or firmware tool to find identifying strings before use. Read and keep the original chip contents first, and confirm the chip marking matches the expected capacity before writing with a programmer.
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.
