@lps I have not tested this out, but via some reverse engineering tricks I know I think this should get you pretty close. Just create a new FOG iPXE menu and add this in as the parameter.

chain -ar ${boot-url}/service/ipxe/boot.php?mac0=${net0/mac}&arch=${arch}&platform=${platform}&sessname=bob || goto MENU

You will need to replace bob with your session name for the multicast image push. That should join you right into the session with one pick on the fog menu.

Ok so as I posted there is a work around and I suspected something in iPXE but I wanted to be sure I wasn’t being a bonehead here. Thanks!

@george1421 Ah ok so if im imaging without registering then location doesnt really do what i need in this case. Thanks though.

I would like to update this thread, we found that the problem was with the DHCP Lease for some reason. We cleared the lease and now it is booting normally. It was very odd that this was an issue because we pulled another of the same machine from the box and it worked without any problems.
