There is no IA64 apple hardware and likely never will be [Itanium]. I think you may have thought I was talking about x86-64 or AMD64/EM64T. EFI was originally deployed on IA64 years ago and FreeBSD has supported it at at least some point. Also my fellow L4 developers have used the FreeBSD EFI-enabled bootloader to load L4 programs. That's all I was referring to, I didn't mean to imply anyone has run FreeBSD on Apple intel hardware. Dave
