BIOS firmware archive for the Dell Latitude 5300 built on board 18827-1, with the name pointing to a 32MB flash image. The 18827-1 style number follows the Wistron pattern, so Wistron is the ODM behind this mainboard. Technicians use such a dump to recover a board that will not post or has corrupted firmware by writing it to the SPI chip with a programmer such as a CH341A. Confirm the board number on the PCB matches, read and save the original chip contents first, and make sure the image size equals the chip capacity.

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 →
