As I mentioned, I don't net boot on those interfaces - that
was just an example for the syntax for other subnets.  To
boot, you need to supply the rest of the values you find
inside the other scope.  In particular you need
next-server, filename and  root-path options for booting.
I'm not sure if you can move that whole stack of
if/else/ logic to the global section of the file
or if you have to repeat it for each scope to handle
the PXE and ppc variations (which is why I didn't give
an example before). It might be best to repeat it and
change the addresses to the appropriate server interface
address for the subnet.  Anything within the {}' for
one subnet isn't done on the others.
