BIOS firmware for the Dell Latitude 3440, Wistron motherboard 213247-1, in a 13.2 MB RAR archive. The name gives no version number or flash capacity, so inspect the extracted files to see whether they are a full SPI image or a region-only file. Wistron boards made for Dell use this six-digit-plus-dash numbering on the PCB. Images like this are written to the SPI flash with an external programmer when the laptop is bricked. Back up the original chip first and compare the image size with the chip capacity before writing.
