BIOS dump for the Chewbacca 14 platform, Kaby Lake-R UMA design with integrated graphics, board 17879-1B and PCB part 448.0E809.001B, in an 11.0 MB RAR archive. The five-digit board number with a hyphen suffix follows the pattern Wistron uses, though no laptop brand is given. Technicians write such images to the SPI flash with a programmer to recover a non-booting board. Match the board number and revision on the PCB, save the original chip, and verify the image size against the chip capacity.
