Hi again, I'll quit my constant posting in a moment. :). I forgot to mention that prior to attempting to boot into 64-bit mode, I made sure my EFI was 64-bit. Those are the only requirements I know. The processor is the right one, and the EFI is capable. But the interesting thing is that holding down 6 and 4 doesn't do anything.
