BIOS for the Dell Latitude 3460 Mobile Thin Client, project LOVE14BDW, built on board 14290-2, which follows Wistron numbering. BDW most likely refers to the Broadwell platform. The 17.7 MB RAR is larger than a single flash image, so it may hold a full dump plus extra files. Extract it and choose the correct image for your chip. Read and save the original flash first, since Dell dumps contain the service tag, and verify the board number and chip size before programming.
