So does that mean it already includes PAE, or something else ?
One of those two. You sure you didn't install a 64-bit version of Ubuntu? > Aside, I will read up on PAE.

Maybe that's off base, it's > only what "i've heard" We're deploying a lot of 64 bit stuff around here. Our experience has been that the OS is as solid on amd64 as it is on i386. Server applications are the same. There are, however, a lot of desktop applications that are still flaky on 64-bit -- mostly non-mainstream ones. We got in a crunch and had to reinstall a workstation back to i386 because of it, or I would have filed some bug reports. -- Bill Moran Collaborative Fusion Inc. _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
