Na simpleArbiter preberi naslove IP_GW, IP_DHCP, IP_B ter ime datoteke BOOT_FNAME. Na DHCP_server postavi DHCP strežnik s pomočjo ISC dhcp 3 na naslovu IP_DHCP. SimpleArbiter naj dobi IP_GW. DHCP_server naj ga uporabi kot gateway. Če se zaganja BootableClientB, naj se sistem zažene z live ISO in dobi svoj IP. ISO je priklopljen na DHCP_server. Če se zaganja katerikoli drug, naj se sistem zažene v datoteko z imenom BOOT_FNAME. Tako BootableClientA kot BootableClientB naj bosta brez diskov.
