WinPE 2 on Itanium Using WAIK 1.1 (Server 2008)

[Hysteresis]

Anyone tried to create a WinPE 2 build on Itanium using the new WAIK 1.1 (based upon Server 2008)?

I've tried to create a test using just these 2 lines (as suggessted by the WAIK CHM file for DVD RAM build):

copype.cmd IA64 c:\PE2

ocsdimg -n -bc:\PE2\efisys.bin c:\PE2\ISO c:\Temp\IA64PE.iso

This I think just takes the supplied boot.wim and adds the EFI boot file to the image. If I burn this ISO to CD and boot on my test box (Dell Itanium 2 PowerEdge), I get the "Windows is loading files ..." message with the progress bar, this gets to 100%, the screen clears and I get.....a blank screen.

If I repeat the same procedure for an x86 build (replacing efisys.bin with etfsboot.com) and just use the same 2 steps I get a working WinPE 2 environment. Do I need to do anything else to get this to owrk on IA64?

Any ideas gratefully received.
