That's interesting, here at Lancaster we've seen very few problems with UEFI PXE other than the fundamental one of some old hardware not supporting it even on their latest firmware, but that's not been an issue on anything that we've bought in about the last four/five years. All our more recent kit is Lenovo but there is still a fair amount of Dell out there. Saying that we don't do all the mass-reimaging via WoL that you do so maybe that's a factor? Phil
