Working BIOS image for the Wistron motherboard 213109-1, stored in a 9.27 MB RAR archive. The name marks it as OK, meaning it was reported to boot after flashing, but it gives no brand or model. Five or six digits followed by a dash revision is a typical Wistron board code, and these boards are built for several notebook brands. Extract the dump and compare its size with the SPI chip before programming it with a CH341A or similar tool. Always read and keep the original contents first.
