Zipped BIOS dump for a Lenovo Flex 2-14D on the LF145M mainboard, Wistron board number 13287-1, compressed to 2.46 MB. The image inside is meant to be written to the SPI flash with a hardware programmer, such as a CH341A-type tool, when the stock BIOS is corrupted. Wistron numbers boards as five digits plus a revision. Read and save the original chip contents first, and confirm that the image size equals the chip capacity, otherwise it will not fit or will not boot.
