I have no idea about PXE, but I know DHCP, using it professionally since a
least 10 years.

Let me be simple in my answer : You CAN'T use two DHCP servers in a single
network, because of the way the lease request is done. It's a broadcast to
the subnet. Look at the RFC for DHCP.

But, it is possible to affect in the DHCP server an IP for each mac
addresses. I think it's the way to go.
