RAR archive, 7.77 MB, named MeViper 3.0, apparently a utility package related to Intel Management Engine work. The name gives no device or board details. Tools of this kind are generally used to analyse, clean or rebuild the ME region of a BIOS dump before it is reflashed to the SPI chip. Scan the contents and read any instructions before running anything. Always keep the original dump read with a programmer, so the board can be restored if an edited image fails to boot.
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 @cidschematicandboardviewofficial. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
