Archive for a board identified as ATB250, also marked B250DA1, with the word chine in the name, likely meaning a Chinese-made board. The B250 in the name points to a board based on the Intel B250 chipset, but the contents are not stated. They may be BIOS dumps or documentation, so inspect the 4.77 MB RAR before use. When flashing any firmware from it, back up the original SPI chip and check that the image size matches the chip capacity.
