Usually you don't want the dhcp and tftp server to be different machines.
The PXE Roms are really buggy in this part, I've never managed to put
them to two addresses. Even if you manage to get it running from
one network card maybe even a different revision of the same card
won't work with this. Not to speak of different network chipsets ...
There's a so-called 'PXE server', which is sort of a DHCP server, running
on port 4011 (AFAIR), it tells where the bootfile and the tftp server are,
and doesn't give out IP addresses. I also don't recommend this, since
it's also buggy in various network cards.
