Syslinux - Mar 2011 - Most efficient way of pxe booting windows pe

Hi guys,

We are using syslinux (memdisk) and gpxe already for a while.
Also got a working winpe boot method by means of pxe. Which basicly is a dd of
an 'recovery partition' where winpe.wim is on.
That method isn't really the most efficient way, cause its loaded into
memory twice.

We are going to do a major windows 7 deployment soon and i'm looking for the
most efficient way of booting a small winpe.
Can anyone tell me the options and what is the best and most efficient method of
today into booting a winpe.wim?

Thanks in advance!

We're using PXELINUX with memdisk to boot a WinPE ISO (RAM disk,
http://technet.microsoft.com/en-us/library/dd799303(WS.10).aspx),
transferred by HTTP using gpxe. Takes about 15 seconds to transfer on a
LAN.

Our 64-bit ISO image is ~172 MB, even when loaded twice we're only
talking about ~350 MB RAM. Our Windows 7 machines have 2048-4096 MB RAM,
can't see the problem.
