If you're like me, & have no idea exactly what ASUS' PEG Link Mode does, then head on over to ARP, as I'm about to do, & read all about it.

"There have been hints that ASUS kept quiet about PEG Link Mode because they wanted to upstage their competitors by shipping motherboards that magically outdo their competitors. Of course, the secret was soon exposed and ASUS was literally forced to reveal the PEG Link Mode as one of their unique motherboard features."
