PXE boot a Raspberry Pi 3 client from a Raspberry Pi server

Hi, I have three Raspberry Pi computers: 1 as server (Raspbian Linux installed) and 2 as client (Raspberry Pi 3, PXE prepared, without any SD cards). I want to pxe boot the 2 clients and a separation by mac addresses is also required. Some tutorials are on the internet but: - I want to boot client #1 (e.g. aa:aa:aa:aa:aa:aa) from server's path /srv/tftp/raspbian/client1. - I want to boot client #2 (e.g. bb:bb:bb:bb:bb:bb:) from server's path /srv/tftp/raspbian/client2. Payment after delivery. Finalization as soon as possible. Please answer with "Raspi pxe", otherwise I will not start a communication.
