Tested BIOS dump for the Wistron motherboard 17934-1, labelled LS730WH, distributed as a RAR archive of about 13.8 MB. The 17934-1 number follows Wistron's numbering, and the same board appears in Lenovo Yoga S730 files. The tested tag suggests the image has been flashed successfully on a working board. It is meant for writing to the SPI flash with a programmer when firmware is corrupted; read and keep the original chip contents first, and make sure the image size equals the chip capacity.
