Can't figure out to to boot to my SCCM Server

[NiKiZe]

normally when you boot ipxe it will perform autoboot, that is run dhcp and then chain to the filename provided by dhcp.

iPXE uses ipxe scripting and commands, the most used command to boot anything is chain : http://ipxe.org/cmd/chain there is lots of other commands as well that you can but in a script and chain to that script : http://ipxe.org/scripting

We will need some more information about what you want to boot to be able to help further
