BIOS image for the Dell Latitude 5540 on board 203032-1, sized for a 32MB SPI flash chip and packed as a 10.7 MB RAR archive. The board number follows the Wistron pattern, so Wistron is the ODM behind this design. Images of this size usually carry the full descriptor, ME and BIOS regions. Back up the original chip with a programmer before writing, because it holds machine-specific data. Confirm that the board number on the PCB is 203032-1 and that the chip really is 32MB.
