The BIOS
Gigabyte has once again gone with an Award BIOS - and once again, to get access to the "hidden" advanced settings you have to press CTRL-F1 before entering their "MB Intelligent Tweaker" menu.
Once you do CTRL-F1, you get access to far more tweaking features :-)
(My apologies for the poor quality of BIOS screen captures; I used a high resolution camera that somehow ended up with extremely strong moire effects. I've reduced the moire in Photoshop at the expense of some blurring.)

Here is the "Standard CMOS Features" menu - nothing unsual, other than listing 10 channels.

Here are the details on once channel:

The "Advanced BIOS Features" let you control boot priority, "Speedstep" and virtualization.

The "Integrated Peripherals" menul lets you choose RAID vs. "Normal" mode for SATA, and lets you enable/disable various on-board peripherals such as audio, lan, etc.
