I'm totally new to this forum. Maybe this is why I can not run the fedora core 4.0 x86-64 boot disk? I have a dual Xeon with EM64T and I'm currently running Win-XPro and have loaded Win64 as well, but I want to load up Linux so as to utilize my 4 gig of ram or else I'll stay with windows :-( Any help would be appreciated.

In fact, Intel adding NX to their instruction set months before EM64T so there may be quite a few boxes out there that don't boot at all unless the bug only shows up on x86-64 capable boxes?
