Archive for an H61M-HVS motherboard, revision 1.00, packed as a RAR of about 337 KB. Its name does not say whether it holds a boardview, schematic or firmware, so inspect the contents before planning a repair around it. Verify the model and the 1.00 revision against the PCB markings. If it contains a boardview, open it in a dedicated viewer to find parts and test points. If it is a BIOS image, dump and save the original flash contents first and check that the file size matches the chip.
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 @cyberlanelectonik. Enginerys does not host this file.
