Firmware archive labelled ds-80235_p with revision 1.2, about 14.2 MB in RAR form. The name does not identify the brand or device clearly, so open the archive and look for readme files, image names or headers that reveal the target hardware. Before writing any image, read and save the original flash contents with a programmer. Check that the image size equals the chip capacity, since a mismatched file will not fit or boot. Use it only after confirming that the board identification matches.
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.
