Here is a good article on configuring optional dhcp parameters in cisco ios.

http://ciscoarticles.com/Cisco-IOS/Defining-DHCP-Configuration-Options.html

You just need to define
option <option number> <option parameters> within the scope of the dhcp configuration.

Let me know if you need further help.

You typed in what you needed.  If you already have your dhcp pool set up, but just need to add the options, type in the commands you listed earlier and refresh the lease on a client.

I assume there are some thin clients you are wanting to boot and pull an image? Or something similar?
