Hi Christian, Yes I have tried different filename options later in my dhcp.conf for fallback such as ipxe.efi or undionly.kpxe but the issue is that the former condition for user-class "iPXE" is never met and always go the fallback filename specified.
I've tried the Robin's example s already and also followed the ipxe forum but couldn't get it working yet.

I tend to refer to Robins extensive example at https://gist.github.com/robinsmidsrod/4008017 see ipxe-green.conf for ideas Other then that I would start checking with tcpdump for exactly what is sent both ways.
