Postavi štiri navidezne računalnike - simpleArbiter, DHCP_server,
BootableClientA ter BootableClientB. Na simpleArbiter preberi naslove IP_GW, IP_DHCP,
IP_B ter najdi datoteko A.
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.
Če se zaganja katerikoli drug, naj se sistem zažene v datoteko z imenom A.
Tako BootableClientA kot BootableClientB naj bosta brez diskov.
