BIOS dump for the Dell Latitude 7350 on board 223117-1, archived as a 24.6 MB RAR. The numeric 223117-1 style matches Wistron's numbering, so Wistron is the ODM behind this Dell board. The name gives no BIOS version or chip type, so check the contents before use. Technicians write such an image to the SPI flash with a programmer to revive a board with corrupt firmware. Read and save the original chip first, since it carries the service tag and system data, and make sure the image size matches the chip.
