Archive for the ASUS A7J, 1.06 MB in RAR format, with no indication in the name of whether it contains a schematic, boardview or firmware. Extract it and review the contents before relying on it for repair work. Material like this is used to follow power rails and signal paths, find components and test points, or reprogram a BIOS chip with an external programmer. Match the motherboard number and revision printed on the PCB, and always back up the original chip before writing any image.
