Thank you for the quick reply Len, but it raised more questions in my mind than it answered.
As for why I am doing this, it is a project that I am working on. I need to boot physical machines using virtual images via network. One use of the project is to keep each file systems as a single file on the server and booting from there. The physical machine will be dummy terminal with nothing much on it. Booting the physical machine is only part of the bigger problem which is to boot it via a network.
