You can find instructions on embedding scripts at

  http://ipxe.org/embed#embedding_within_the_ipxe_binary

To create a bootable USB image with an embedded script, you will need 
something like:

  make bin/ipxe.usb EMBED=myscript.ipxe

where myscript.ipxe contains an iPXE script similar to:

  #!ipxe
  dhcp
  chain http://my.web.server/boot.php

This image can then be transferred to a USB key using

  dd if=bin/ipxe.usb of=/dev/sdX

You will need a Linux system in order to build iPXE (or any Unix-like system, 
such as Mac OS X).
