I have seen several locked threads regarding this, is it still not an available feature?
I see network booting in the gui - but I assume this is not actually option 66.
Is this as good as it gets - http://forum.pfsense.org/index.php/topic,1192.0.html
I need this for phones, its hard to believe we have come this far and still dont have this option. It would be nice if the DHCP page was similar to the OpenVPN page where a box is given to add additional custom options.
I know - its hard for me to complain since i am not a coder, but it seems simple.
