Newb to unlocking

Ok I looked at the toms hardware unlocking video and but he doesnt show it for the L5 for dual smp anyone where to unlock the L5 bridges?

I just got 2 xps 1600 today and im scared I might do something wrong I need to unlock the cpu and unlock it for smp HELP!!!!!!!!!!!!!!!!!!!!!

Ask this question in the SMP forum. I think there may be a sticky in there that talks about it as well. You can also do a search.
