I came across the same problem some weeks ago and solved it<br>
by using a 64-bit build of iPXE: As pointed out by Michael,<br>
those can be built with<br>
<br>
make bin-x86_64-efi/ipxe.efi<br>
make bin-x86_64-pcbios/ipxe.pxe<br>
<br>
I've also made patches for 32 bit to support images over http<br>
larger than 2 GB (in theory up to 2**63 bytes, tested with<br>
a 32 GB image), if you really need 32 bit support now you can<br>
apply those patches for now:<br>

(@Michael: sorry for the long delay, I promise to try what you suggested<br>
this week and get back to you).<br>

<br>
Currently, the only way to support diskless Windows clients I know<br>
of is iSCSI (there might be others). As Christian Nilsson pointed<br>
out, Windows only loads the neccessary kernel, drivers and registry<br>
hives in the early boot process and eventually a Windows driver must<br>
provide the System Volume somehow. Just as with Linux (and other<br>
Unices), if the System Volume / root device is not present the<br>
kernel BSODs / panics.<br>
<br>
We are, however working to support boot device as DRBD device (for<br>
diskless clients) for our (Linbit) WinDRBD kernel driver (see<br>
<a href="https://github.com/LINBIT/windrbd">https://github.com/LINBIT/windrbd</a>) and will probably have<br>
something useable in a few months. In our solution you would<br>
boot Windows via iPXE and http from a DRBD device (with a small cgi-bin<br>
wrapper) and once Windows is booted, provide the Windows System Volume<br>
as a regular (Diskless Primary in DRBD speak) WinDRBD block device.<br>
That way you can have setups with redundant servers as well.<br>
<br>
What exactly are you trying to build?<br>
<br>
Cheers,<br>
