WinPE OEM environment only ADO no DS

Hello , we are running altiris 7.1

For WinPE boot we have some custom actions scripted, the script is pulled from the bootwiz\oem\DS folder , file runagent.bat

Now when we create a new WinPE we can only select ADO for OEM, and for ADO there is nothing specified in the OEM folder. So also no custum actions

Question:  how can we make DS visible again when the creating  a new winpe?  Or as alternative how can we create an ADO folder with all the correct files and our runagent.bat script.

Thanks
