RAR archive for the Z96FM board, revision 2.0, 1.33 MB in size; the name does not say whether it contains a schematic, boardview or firmware, so extract it with WinRAR or 7-Zip and inspect the contents. The revision tag matters, as rev 2.0 material should be matched only against a PCB printed with the same revision. If a flash image is inside, read and save the original chip contents with a programmer first, and confirm that the image size equals the capacity of the installed SPI 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 @schematicslaptop. Enginerys does not host this file.
