BIOS dump for the Dell Vostro 3550 on Wistron mainboard 10245-2, project DQ15, Intel version. The Wistron five-digit number with a revision suffix is usually printed on the PCB. The Intel tag separates this board from AMD-based versions, which need different firmware. The 2.09 MB RAR likely contains an image for a 2 MB flash chip. Technicians program it with a CH341A or similar tool to fix a corrupted BIOS. Confirm the board marking matches, and keep a copy of the original chip before writing.
