Compact archive, about 502 KB, for a board labeled G41D3 with a W suffix. The name points to an Intel G41 chipset platform with DDR3 support, though the W marking is not explained and no maker is given. Contents are unspecified and are probably a BIOS dump given the size, so unpack and check before use. When reflashing, back up the original SPI chip with a programmer and confirm that the image fits the chip capacity. Also make sure the board marking matches exactly, as similar names exist.
