BIOS dump for the Dell Latitude 5300 laptop on motherboard 18827-1, reported as working, in a RAR archive of about 19.8 MB. The number with a dash suffix follows the Wistron scheme, the ODM that manufactured this board for Dell. Such a dump is used to restore firmware on a board that will not POST, written with an external SPI programmer. The archive size suggests more than one image, so check the chip capacity and choose the file that fits, after saving the original contents.
