I've done this in a lab. PXEChaining means passing PXE instructions on to another PXE server.
In my test, this is what I did. Install WDS on a "main PXE server" Add the necessary PXELinux files and edit the service and the menu files to forward PXE requests on to the next PXE server, the SCCM server, cobbler, another WDS, etc.. My original intent was to provide central PXE address for everything, Linux, SCCM and WDS, and just forward each request depending on the menu item chosen. It worked in practice, but because there is always a choice, zero touch is no longer an option. Because we image servers using zero touch I scrapped the idea. My server task sequence depends on being able to PXE again and make it back to the SCCM server, during the sequence. But yes, it works.

It has a GUI which allows user to select which boot image to use. The boot image must then redirect to the sccm server. Unless I am missing what true chaining is, I haven’t heard the term before Andy -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Tigchelaar, Martijn Sent: 09 January 2014 13:51 To: [email protected] Subject: RE: [mssms] PXE Chaining to SCCM 2012 R2 from PXELinux Craig, In that case you are basically loading a regular boot WIM of the PXE server. That is not the same as chaining from PXELinux to SCCM. I think the true chaining option is preferred. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Andrew Craig Sent: Thursday, January 09, 2014 1:26 PM To: [email protected] Subject: RE: [mssms] PXE Chaining to SCCM 2012 R2 from PXELinux Yes. And it works. I create a bootable media from sccm, then modify this and upload to an existing wds infrastructure which uses a custom pxelinux setup. You need to extract the boot wim from the bootable media and copy the sms data from the root of the media to the wim, reseal and then upload this to the pxe image store. I have a document somewhere with exacter instructions, I'll try and dig it out this afternoon -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Richard Sent: 09 January 2014 13:14 To: [email protected] Subject: [mssms] PXE Chaining to SCCM 2012 R2 from PXELinux Hi Anyone one tried (and succeded) to implementent SCCM 2012 R2, into an existing PXE infrasstructure ? The hope is to just add a menu item to the PXE Boot menu, and then pass the control onto SCCM. Current PXE setup is based on PXELinux. rg Richard This e-mail message and any attachments may contain legally privileged, confidential or proprietary Information, or information otherwise protected by law of Meritor, Inc., its affiliates, or third parties.
