Oops! I installed FC6 i386 on a new box: Dell OptiPlex 745 with core 2 duo em64T CPU. It should have been x86_64. Is it worth changing? Can I 'upgrade' or do I need to do a new clean install? Thanks guys! Bill Ps I have / and /home is separate partitions - if I do a clean install can I just throw away the / partition and keep /home?
