BIOS image for the Lenovo Flex 2-15, platform LF15M, motherboard 13308-1, stored as a 3.18 MB RAR archive. The five-digit board number with a dash suffix is Wistron numbering, identifying Wistron as the board maker. Technicians write this dump to the SPI chip with a programmer to recover a board with no post or a corrupted firmware region. Read and save the original chip contents first, since they hold serial and system data, and make sure the PCB carries the same number.
