Booting pxelinux.0 without dhcp available

[Thomas Schweikle]

How do i configure grub2 to boot pxelinux.0 from tftp servers, but
without any dhcp server available?

What I'd expect it to do: load pxelinux.0, then load
pxelinux.cfg/default, start pxelinux.0 with loaded configuration
"default".

Using

menuentry "pxechain" {
   set net_default_server=tftp.remote.dc
   pxechainload /pxelinux.0
}

leads to loading pxelinux.0, starting pxelinux.0, but then pxelinux
asks dhcp for data and since there is no dhcp (or one who does not
know anything about the system in question) pxelinux.0 fails to find
any configuration file.

Is there any way to load pxelinux.0 in a way together with its
configuration file to have it not ask dhcp again, but just start with
the given configuration?
