Dell BIOS dump for Wistron board 17831-1, described in the name as tested and working, in a 5.42 MB RAR. Wistron uses five-digit numbers with a dash revision like this on many Dell Inspiron and Vostro boards. The image is intended for reprogramming the SPI flash with an external programmer when the laptop will not POST. Even with a confirmed good dump, read and keep the original chip first and check that the file size equals the chip capacity.
