Broadcast the next server for mobile NetBoot?

[MikeyCarter]

I want to turn my laptop into a mobile NetBoot station for doing Fedora Linux upgrades.

Problem is most DHCP servers you can't add the BOOTP stuff to. Nor do I want to override the DHCP server, especially if I'm on a public network.

So first question, is there any way to have my laptop broadcast it's a "next server" or has a ipxe boot file?

If not a broadcast is there any way to hard code the ipxe CD disk to have the laptop address?

I realize I can chain it from the command line... just want to automate it so I insert the disk and it just loads.
