Use variables and settings to help get to hooking capabilities in BootMenu.class.php.  Commonize many areas to send and parse data.  Still testing, but no more direct print statements.  Prints are all done by a new function called parseMe and takes two arguments.  First argument is the data to print for ipxe, second argument is if the element being printed needs to pass to chainboot.  Chainboot is already setup to parse the data as well.
