We have a series of HP Thin Clients deployed which support their ezUpdate protocol. On boot, it checks in with the DHCP server and looks for tag 137 to get the FTP URL to connect to to check for updates. Our DHCP server is ISC DHCPD and I cannot determine how to configure the options to give out this tag/code with the rest of the DHCP lease information. This is my first foray into ISC DHCPD so please be gentle. Any guidance is appreciated.
Note: The content of the tag would be a string with a URL in the format
