Just started to play with the Menu Editor and the defmenu.mnu and
example.mnu files in the same directory. The example.mnu shows an option to
load DOS utils with a command of "boot.dnx dosutils.bin". My question is,
what is dosutils.bin and where can I get it? Similarly, how can I make use
of PXE to boot to a DOS Client32 boot file? What exactly are BIN files? I
went over the ZfD6.5 docs but they do not go into the details.
