Firmware dump packed in RAR for a board labelled DS-80255 P, revision 1.1; the name does not state which device or brand it belongs to, so confirm the identity by matching the PCB silkscreen. At 15.8 MB the archive likely holds a full flash image read from the board memory. Dumps like this are written with an SPI or EEPROM programmer to recover a unit with corrupted firmware. Before writing, back up your own chip, check that its capacity matches the image size, and verify the revision printed on the board.
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.
