Unlocked BIOS image in a 1.39 MB RAR for a board coded M841, at the DVT stage, meaning a design validation build rather than final production. Unlocked normally indicates a password or security lock has been removed from the dump. No brand is named, so confirm the M841 marking on the motherboard before flashing. Read and keep the original SPI chip contents with a programmer first, and check the image size equals the flash chip capacity so the write will fit.
