Does PXE boot require DHCP?

PXE Boot Basics.

Booting from the network using the PXE protocol involves a simple series of DHCP packets. There are three parties involved: the DHCP server, the PXE server, and the client. The client broadcasts a DHCP packet asking for the address of DHCP servers (servers that can hand out IP addresses).

Can you have two PXE servers same subnet?

First, if the network is divided up into subnetworks, the broadcast request will only extend to the computers on the same subnetwork, and so many PXE servers can co-exist if each is on a different subnetwork. A second solution is possible with server software like Microsoft System Center Configuration Manager.
