Archive for an ITX-3317U-6CD8 board, marked ok tested in the name, 2.82 MB in RAR form. The name suggests a mini-ITX style board, with 3317U possibly pointing to the processor, though no brand is given. Contents are not listed, but the size fits a firmware dump for the SPI flash. Use it to reflash a board that fails to post. Match the board name on the PCB, back up the existing chip with a programmer, and check that the image size equals the flash capacity.
