Small firmware archive named only M26G4 A09, 370 KB in RAR form, with no brand or board number given. The A09 suffix looks like a revision or version label, but the device it belongs to cannot be determined from the name alone, so inspect the contents and any notes before use. Files of this size often hold EC or small BIOS images rather than a full modern SPI dump. Identify the target chip on the board, read and save its current contents, and only write once the size and target clearly 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 @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 →
