Several motherboards that I've owned had "hidden features" in the BIOS that could be accessed with some combination of keystrokes. Now, I'm working with a XPS 8930, and am wondering if there's something similar that will access some of the stuff that's either grayed out in the settings (or hidden altogether). For example, I'm not finding any way to disable items like the onboard sound and graphics. I should note that, at one time, when you plugged a graphics card into and AGP or PCI-E adapter slot, the onboard graphic would be disabled automatically. As is, the sound and graphics hardware get's setup by Windows and clutter up the software environment. I simply want to get rid of the devices and run the system as cleanly possible. Searched for this, BTW, and didn't find anything that seemed applicable to the 8930.
