[gPXE] x86_64-efi build

[Mike Bishton]

Hi Josh,

Thanks for getting back to me.

Thats good news, hopefully that means that I shouldn't run into too many 
more difficulties moving forward :). I only brought up the question 
about native EFI support because I've heard that Apple butchered the 
spec for their firmware.

I'll work on getting write permissions to the wiki this afternoon so I 
can start helping out with documenting the EFI build process.

Like I said before, I haven't really put much time into debugging this 
myself, so I certainly don't expect you to. But, since you asked, here 
is the output so far:

As you can see I built with the shiny new e1000e driver (Thank you Marty 
and NGC :) )
The extra debug you see is a result of having the debug output enabled 
in the system firmware. Hitting Ctrl-B when prompted also causes the 
exception.

Thanks,
Mike
