Well? I thought the 2006 and 2007 Mac Pros have 32bit EFI. How come then is the 2007 Mac Pro not listed under Apple's unsupported hardware for Windows 7 in Boot Camp 3.1 today? On my 2006 Mac Pro, I can't boot from the 64bit Windows 7 retail DVD and I assumed it was the same for the 2007 Mac Pro... so how did they get so lucky? I'm really confused now. What's so wrong with 2006 Mac Pro?
