Firmware for the Intel DX79SR desktop motherboard, an X79 platform board, bundled as BIOS plus EC firmware in a 2.19 MB RAR archive. The name gives the BIOS flash size as 8 MB, so the main image should match an 8 MB SPI chip. The EC image belongs to the embedded controller handling power sequencing and fans. Use a hardware programmer to restore a board that fails to post after a bad update. Read and keep the existing chip contents before writing, and check each file against the chip it is meant for.
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 @biosarchive. Enginerys does not host this file.
