According to Wikipedia, the following started supporting EFI at some point:
Linux with elilo HP-UX on IA-64 OpenVMS OSX Windows 2000 on Itanium Windows Server 2003 for IA-64 Windows XP 64-bit Edition Windows blah blah. EFI is the only supported mechanism to boot OSX, I believe, and BIOS is the only supported mechanism to boot basically anything not in the list above. The list fortunately has most important OSes, but that would include DOS for example. Basically, OSX has switched completely because they control the whole hardware stack. I think everyone else is switching too, but because people apparently still want to run windows 95 on their 16 way super servers they're taking longer.
