[Etherboot-developers] [COMMIT] 5.1.2+ boot from disk.

[Eric W B. <ebi...@ln...>]

The fun part.  With nic and network drivers compiled in I had
etherboot booting itself over the network, then unplugged my nic
cable and instantly booted from my IDE disk.  So the boot order code
now works.

I have commited my infrastructure refactoring to allow etherboot
to boot from disk.  The biggest change is that I have moved
most of the code out of main.c and into nic.c so I could
seperate out which parts were generic etherboot and which parts
pertained to booting from the network.

I have transformed the loop in main.c into a state machine so
there is now less duplicated code.  I believe the transformation is
correct but I may have missed something minor.

And there is now an extra state that loops through the various
kinds of hardware.

The remaining features is to add the ability to set the boot order.

Beyond that everything should just be testing and bug fixing until
we are certain everything is stable enough for 5.2.
