RAR archive of 515 KB for the ASUS A58M-E motherboard, a micro-ATX design with the AMD A58 chipset and an FM2+ socket. The contents are unspecified by the name, though the size suggests a boardview, a schematic or both. Use them to follow nets from the power connector, check VRM MOSFETs for shorts and locate the BIOS chip. Extract the archive with WinRAR or 7-Zip, and verify the revision silkscreened on the board matches before relying on it.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @boardview. Enginerys does not host this file.
