SCCM 1606, blackscreen winpe boot

[harry9]

Hi guys!

I'm new to ipxe and feel a bit lost and looking for some help. I am getting stuck in a blackscreen after loading the SCCM 1606 boot image on client.

Using:
wimboot 2.5.2
winpe 10.0.10240.16384

ipxe-config:
#!ipxe

kernel http://deploy/wimboot/2.5.2/wimboot
initrd http://deploy/bootmgr.exe bootmgr.exe
initrd http://deploy/Boot/BCD BCD
initrd http://deploy/Boot/Fonts/segmono_boot.ttf segmono_boot.ttf
initrd http://deploy/Boot/Fonts/segoe_slboot.ttf segoe_slboot.ttf
initrd http://deploy/Boot/Fonts/wgl4_boot.ttf wgl4_boot.ttf
initrd http://deploy/Boot/boot.sdi boot.sdi
initrd http://deploy/sources/boot.wim boot.wim
boot



Followed instructions: http://ipxe.org/wimboot and http://ipxe.org/howto/sccm

Tried to:
* Added drivers to boot image. (Running VM on a KVM-plattform.)
* Copied bootmgr.exe, as instructed http://forum.ipxe.org/showthread.php?tid=5948

When trying to boot against an .wim file created from MDT2012 everything boots up as expected.

Do you guys have any tip where I should start looking? Know you may need more information from me about this.

Thanks!
