Firmware archive named by a board code, 71R-A14HV6 with suffix T840; the name states no brand, model or chip type, so confirm the code against the label on the motherboard. The 1.84 MB RAR is likely a BIOS image intended for direct SPI flash programming. Use a CH341A, RT809H or similar tool when the board does not post after a failed update. Read and keep the original chip contents before erasing, and make sure the unpacked image size equals the capacity of the installed flash chip.
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.
