Well I hate when people say this, but I'm going to say it.. :) When I did a default install of ubuntu, it saw all 4 gigs without a hitch. So does that mean it already includes PAE, or something else ? Aside, I will read up on PAE. I'll read up about 64 bit as well, I've been hesitant to make the jump only cause any word of mouth i've heard said that it's not ready for production. Maybe that's off base, it's only what "i've heard" Thanks ! Jeff.
