I believe they both do. Are you referring to the KT266A Pro2? If so yes, definately. I have this board & no jumpers, just BIOS. On the down side the FSB adjustment is a bit odd. If you set the CPU FSB as 100 you get 100 - 132mhz FSB adjustments, if you set the CPU FSB to 133 you get 133 - 166mhz adjustments. A bit strange, but workable.
Now don't even get me started on that annoying D-LED buzzer/CPU warning setup - lol.
