Compressed firmware of 1.80 MB identified only by the part number 71R-A14HV6-T840, which belongs to the same A14HV6 board family as the T810 and T821 releases. No board version or device model is given in the name, so compare this code against the label on your PCB before use. Such dumps are written to the BIOS flash chip to revive a board that does not POST. Read and preserve the original contents first, and confirm the image length matches the flash 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 @biosarchive. Enginerys does not host this file.
