Firmware for the Dell Latitude 5310 on board 19840-1, holding a 32 MB BIOS and marked as OK. The archive is about 22.7 MB compressed. Five-digit numbers with a dash suffix like this follow the Wistron board scheme. A 32 MB image requires a 256 Mbit flash, so confirm your chip capacity before programming. Back up the original, since Dell images carry service tag and configuration data, and verify the board number on the PCB before writing with an SPI programmer.
