Hi,

This kind of usage have been around for some time. In grub legacy, it
generates pxe image by catenating pxeloader and pre_stage2.
pxeboot.img is basiclly identical to pxeloader.S, and pre_stage2 and
core.img loaded at the same address, so it can conclude pxe image can
be built by combining pxeboot.img and core.img. But I agree that
perhaps not many people know about it, it's a good idea to write some
doc in the wiki.

BTW, any comment on the content of the patch ?
