BIOS dump for a V470 notebook with a Core i7, board LA470 MB, discrete-graphics version 10250-2N, reported as working by the name. The DIS tag means a dedicated GPU build, so it should not be used on an integrated-graphics board. The 10250 board code follows the Wistron numbering pattern, with the suffix marking revision. After unpacking the 2.42 MB ZIP, compare the image size with the SPI chip, save the original contents with a programmer, and then write the file.
