Yes, that is one of the catagories of rare, a EFI-32 bit system that
was originally shipped with a 32 bit only CPU, that later got upgraded
in the field with a 64 bit CPU, that still runs a EFI-32 bios.
Are you sure the 2007 firmware is EFI32? I would of thought
since they upgraded the base system to a 64 bit CPU they would
of shipped it with a EFI-64 bios.
