Firmware archive listing two board codes, NB5720-MB-U-V2 and NB5729-MB-U-V2, packed in a 6.47 MB RAR. No brand, chip or version is stated in the name, so identify the target from the PCB silkscreen and open the archive to see which images are included. Dumps like this are written to the SPI flash with an external programmer to recover a board that fails to boot. Read the original chip first, keep the backup, and confirm that the image size matches the flash capacity before writing.
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.
