wimboot: no bootmgr.exe

[VirtualNobody]

I'm trying to use wimboot 3.0.1 and pxelinux.0 6.0.3-pre6 to boot SCCM.

I'm getting:
wimboot 1.0.3....

Emulating drive 0x81
Fatal: no bootmgr.exe

This is my menu file:
LABEL Windows SCCM installer NEW
com32 linux.c32
KERNEL wimboot
INITRDFILE windows/bootmgr.exe bootmgr.exe
INITRDFILE windows/bcd bcd
INITRDFILE windows/boot boot
INITRDFILE windows/boot.sdi boot.sdi
INITRDFILE windows/boot.wim boot.wim

If I use initrd instead of initrdfile I get a cpio error, and from googling, initrdfile is what is needed.

bootmgr.exe is from the 8.1 ADK.

A network trace shows no attempt by the client to even attempt to load bootmgr.exe from the server.

I would use ipxe chainload, but that's not currently working for me at the moment (see my other thread on that...)

Any ideas?

Thanks...

I have also tried this, with the same results...again, network trace shows no signs of attempting to load bootmgr.exe

LABEL Windows SCCM installer old
com32 linux.c32 wimboot
INITRDFILE windows/bootmgr.exe@bootmgr.exe,windows/bcd@bcd,windows/boot.sdi@boot.sdi,windows/boot.wim@boot.wim
APPEND wimboot

I have tried with and w/o the @program.

If I use initrd instead of initrdfile, it does load the files, then gives the cpio error.
