I'm on the Pro as well.
Us Pro people will NEVER see a BIOS update that gives us Multiplier options...The Multiplier isn't just a BIOS thing, there's Hardware involved.
So now I'm thinkin my Mom needs a computer, but don't need no Multiplier settings. I could just build her a machine with my Old Pro (perfectly fine hardware) and get myself the Pro2A...I'll be the hero for building her a machine and I'll have the upgrade...SWEEEET!
