annoyed at the lack of a useful pxe boot selector,
I've had a go at writing one.
this is not a pxe boot menu, it's just a bootstrap that you start in place
of your dinic.sys (or any other nbp) and it gives you the option to start
another, with password protection.
it's a front end for the front end.
or maybe a prepreboot?
this is a first attempt at this, and it appears to be working fine
on our (admittedly reasonably new) systems, with dinic.sys and pxelinux.
if you'd like to give it a try, you can fetch the clicky app
please let me know if you use it and it's working fine
and also if it doesn't.
