I have the appliance set up. I have copied in my netboot image and started the service. I believe I have correctly configured my subnets. The server is not in the same subnet as my clients, however I do have the helper address configured on my switch. When I go to startup disk in system preferences I do not see the netboot server. If I start up the machine and attempt to netboot the server is not found. If I manually set the machine to netboot with:
bless --netboot --server bsdp://serverIP; restart
it works!
So how can I get the netboot server to show up in system prefs under startup disk or on boot when holding option?
