Advanced menu and advanced string parsing in iso image?

[NiKiZe]

By using http://ipxe.org/cmd/menu and http://ipxe.org/cmd/prompt you can do most of this.
also take a look at http://ipxe.org/cmd/config

string parsing is not supported in iPXE it's best to do that server side.

Also I would like to avoid possible future missunderstandings...
.pxe most often refer to a NBP PXE bootable binary.
If you have scripts for iPXE name them with the .ipxe extension instead.

So from that I'm assuming that "into the iso image" means by using: make bin/ipxe.iso EMBED=menu.ipxe
