BIOS dump for an all-in-one PC identified as B50-35 with board number 13123-1, in a 2.08 MB RAR archive. The five-digit number with a dash suffix follows Wistron's board numbering, so Wistron is likely the ODM behind this mainboard. The brand is not given in the name, so confirm the system before use. The image is meant for rewriting the SPI flash on a unit that does not POST or has a corrupted firmware. Check the board label against 13123-1 and back up the original chip before writing.
