Firmware archive of about 13.4 MB whose name gives only DS-80249_P and revision 2.0, with no brand or device stated. It is unclear whether the code is a board number or a product model, so open the archive and check the files and any notes before use. Firmware like this is usually written to a SPI flash chip with a programmer or loaded through the vendor's update tool. Make sure the target matches the label and revision, read and keep a backup of the original chip, and verify the image size matches its 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 @emdadbios. Enginerys does not host this file.
