RAR archive of 1.02 MB for board NM-G681 with an RTX 5060 GPU marked GN22-X4. NM-xxxx numbers follow the Compal style, so Compal is likely the board maker. The name does not specify the exact contents, but the size and GPU code point to firmware for this board and graphics combination. Extract it and review the files first. If you program a chip, save the original contents beforehand and verify the board number printed on the PCB matches.
