Found it:

It`s all written in winpe.chm from WAIK.

Walkthrough: Walkthrough: Build a Windows Recovery Solution

All you do is to customize your WINPE to include WRE (Windows RecoveryEnvironment)
You then can take your version of WinPE and put it on HD for maintenance-purposes i.e. when not having install-DVD at hand.

Fine cast.
One question to Windows Recovery Environement.

Will their specials tools needed to put Windows Recovery Environement on HD, as you mentioned OEMS hopefully put it on a partition, or what is the trick?

I wasn`t able to find any info so far.

Thanks,
