This was a one off since we were invited once to a pc lab where most pc's were older but 4 were uefi pc's. We brought a laptop ltsp server with http://ts.sch.gr/repo/livecd/12.04/ubuntu-12.04.5-desktop-i386-sch.iso which is a remastered Ubuntu 12.04 32bit iso. It uses dnsmasq and it just worked with all the clients once we could get the uefi to boot with no secure ipxe.
