BIOS dump for the Dell Latitude 3400 built on the Wistron-numbered 17938-1 mainboard, supplied as a RAR archive of about 14 MB. The name marks the image as working and fully tested. Technicians write such a dump to the SPI flash with a hardware programmer when the board will not post, loops on power-up or has a corrupted firmware region. Read and save the original chip contents first, keep any service tag data you need, and check that the image size matches the capacity of the installed flash chip.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
