[ipxe-devel] WinPE 5.0 wimboot errors?

I'm attempting to boot a WinPE 5.0 image (from the ADK for Windows 8.1 
preview: http://www.microsoft.com/en-us/download/details.aspx?id=39306 
), and I'm running into some issues.  It seems that wimboot is no longer 
able to load bootmgr.exe:

If I compare the old wimboot file (from WinPE 4.0) to the new one, what 
I'm assuming to bootmgr.exe seems to be in the same place:

I'm not certain what the error messages mean, has the bootmgr format 
changed significantly?

WinPE 5.0 apparently fixes a terrible bug in WinPE 4 ( 
http://support.microsoft.com/kb/2853726 ), so I was hoping to be able to 
use it even though it's not officially released.
