chainload with Win2012R2 problem

[udeo]

Hi everybody

I'm new to iPXE. I configured my test environemt (Win2012R2, SCCM, IIS 8.5) according the howto's on ipxe.org.
So far, I get it to work that it boots up to iPXE but after that it can't find the files on the IIS. It says "nothing to boot".
However, if I press CTRL-F8 and enter "chain http://dc01/iPXE/sccm.ipxe" it downloads the wim file and after that I can start the SCCM task sequence.

So I suppose the problem lies in the configuration of my DHCP. Unfortunately, the howto here: http://ipxe.org/howto/msdhcp doesn't work on Win2012R2 anymore. The selection of the user class doesn't exist anymore. Because of that, I created a DHCP policy. But that doesn't seem to work. It doesn't matter if this policy is activated of not. If I boot into iPXE, I always get the error "nothing to boot".

If I can't solve this, I thought of using an embedded script like is is described here: http://ipxe.org/howto/chainloading
Is there any documentation on how and where I have to integrate a script like this?

Many thanks for your help.

You embed your script by running make with the EMBED parameter:

Code:

make bin/ipxe.pxe EMBED=../init.ipxe

You might also have an issue with IIS not properly serving files without an extension. You need to setup IIS to serve them as application/octet-stream.
