Firmware archive for a board labelled LV315KBMB, board number 17807-3M, with part reference 448.0DC05.003M. The five digit number with a revision suffix and the 448 prefix are typical of Wistron-made motherboards. The 10.1 MB zip probably holds a full SPI image, but check the contents before use. It is meant for reprogramming the BIOS chip with a programmer such as a CH341A or RT809 after a failed update or a corrupted dump. Always back up the existing chip and check that the image size equals the flash capacity.
