you only need a crossover cable. what you need is just go to any computer shop and ask for a crossover network cable and they will get you one and paid for it and go home, plug each end to each of your computers. then set the ip address for one to 192.168.0.1 and the other to 192.168.0.2. as for the network mask, just use the suggested 255.255.255.0 and ignore the gateway since you are not using it for online anyway. then you can start sharing files and transfer files between two computers.
