I want to add menu items to the PXE Menu. The PXE Menu Editor allows me to
add/remove items, but how do I create the command script? I have notice
that the default menu items all have the "boot.dnx" file in common on the
command field. But how do I create/modify the .bin files. Is there a way
in Linux to create/modify the .bin files? I am trying to avoid a purchase
cost for preworx.

Any shared techniques will be apprecited

Thanks in advance.
