Firmware archive labelled MX-2 with the year 2011, 2.04 MB in RAR form. No brand or board number is stated, so the target device cannot be identified from the name alone, and MX-2 may be a model or project code. Open it to check the image files and their sizes, which should match the capacity of the flash chip on the board. Before writing with an SPI programmer, confirm the device and board markings correspond, and always read and store a copy of the existing chip contents first.
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.
