aTFTP / UDPcast
It provides the atftpd binary needed to turn a greenGate into a server for PXE booting, as well as the needed libraries. As a bonus, if you wish, you can also install the necessary files to have a UdpCast image (2.6.23.12 kernel) downloaded to clients. You can find the UdpCast homepage here. In brief it allows for easy cloning of PC’s with identical hardware over the LAN, one PC (the model) being the sender and the clients being the receivers. Very simple to use and very efficient! This is just so that you can test the PXE boot functionality with something real and useful.
