I don't have access from C code to grub_gate_a20 or prot_to_real
(unless I don't include the right header files)... However
grub_eltorito_boot ends up being at address 0x872c

I happen to copy 4 sectors, 2048 bytes each, so it would definitely
overwrite the code for grub_eltorito_boot.

So, what do I do in this case? The eltorito specs say the code should
reside at segment 7c0h...
