Is there a way to force Windows Setup to enable PAE (physical adress extension) at start up, like I can do with linux installations ("/forcepae")?
I found an MSDN-Page about Physical Address Extension. Microsoft is telling to use
bcdedit /set [{ID}] pae ForceEnable
but I can't do this before windows setup is loading.

3What exactly do you need to do in Windows Setup that requires PAE? – qasdfdsaq – 2015-07-06T13:19:04.000
I would like to install Windows with PAE support on a Intel Pentium M "Dothan/Banias" based machine, this processor supports PAE - but don't show PAE support flag.

Windows 8 won't install without PAE support, that's why I want to do so – CrazyMetal – 2015-07-06T13:57:48.703
Ah, sorry. I wasn't aware it checked for PAE support. There seem to be a lot of workarounds for installing it on Pentium M's but they all seem to refer to the preview release. – qasdfdsaq – 2015-07-06T14:03:09.277
No problem. My idea is to run setup from custom WinPE, maybe I can change bcdedit there. But I've no idea how to execute Win 8 Setup this way. – CrazyMetal – 2015-07-07T09:38:24.323
Assuming your custom WinPE (is it on a USB?) uses the standard NT kernel (it probably does) then the same BCDEdit command should work just the same when applied to BCD store on the USB stick. – qasdfdsaq – 2015-07-07T10:26:20.963
