5070 failed OS deployment - any ways using PXE?

Hi!

We've got several hundred 5070 and several hundred Optiplex 3000 managed through WMS Pro.

Deploying a new image produces about 1% damaged thin clients - image cannot be installed on that hardware - or something like that and doesn't boot anymore.

I know that PXE isn't supported but is there a way to get PXE working with merlin? Already tried that without success.

Regards, thank you!
