Reporting a successful bios flash for motherboard GIGABYTE GA-X79-UD3
Flashrom reports as multiple different chips, visual inspection shows mine to be "MX25L6406E"
All went smooth, excellent work guys! Much respect!
Put outputs into pastebin so I don't have too much clutter.
Outputs:
flashrom -p internal -V
