Archive for the ASUS Sabertooth X79 motherboard, a 563 KB RAR whose contents the name does not describe. The X79 chipset places it on Intel's LGA2011 high-end desktop platform. At this size the archive most likely holds boardview or schematic-style data rather than firmware, useful for tracing VRM rails, finding shorted capacitors and locating test points. Confirm what each extracted file is, and compare the revision on your PCB before trusting component placement.
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.
