BIOS archive for the K580 built on the Quanta TWH platform, board DATWHMB18D0, the same design used by the A560 and A580. Quanta numbers its main boards with this DA...MB pattern. The dump serves to reprogram the SPI flash with a programmer after a failed update or when the board shows no display. Read the original chip before writing, keep the backup safe, check the board number on the PCB, and make sure the image size matches the chip capacity.
