I sat down with the book last night and read it from front to back (motherboard manual).
On page #20 at the very top it reads,
"In addition, under this configuration, the BIOS Setup and POST screens can only be output from the HDMI port."
This is in reference to having both DVI and HDMI both hooked up at the same time during boot up.
Goes to show, if all else fails. Read the MANUAL.
