A RAR archive holding a 32 MB BIOS dump for the Dell Latitude 5310, board number 19840-1. The 19xxx-x number follows the Wistron numbering scheme often seen on Dell business notebooks. Extract the image and write it to the 32 MB SPI flash chip with a programmer to recover a board that fails to boot or to clear corrupted firmware. Verify the chip capacity and the board code printed on the PCB first, and keep a full backup of the original chip, which carries service tag data.
