Archive of 2.82 MB named IRIS all in one, with no brand, model or board number given, so the target device cannot be confirmed from the name. It may relate to an all-in-one computer or a bundle of several dumps. Extract and inspect the contents, comparing them with a read of your own chip. Never write an unidentified image without backing up the original flash with an SPI programmer and checking that the image size matches the chip capacity.
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 @biosdumpcomputer. Enginerys does not host this file.
