Dell BIOS firmware for the Redwood BMLK platform, Wistron board 14274-1, with the Dell part code 475W5 included in the name, packed as a 4.03 MB RAR archive. Five-digit numbers with a dash suffix follow Wistron's ODM scheme, the suffix marking the revision. The dump is written to the SPI flash with a programmer to recover a dead or looping board. Check that 14274-1 and the code on the PCB match, back up the original chip with its service tag data, and verify the image size equals the chip capacity.
