Ethernet Crossover Cable - You first must have an ethernet network interface card (NIC) in both computers to use this method. If you are using ethernet cards with RJ45 jacks (similar to a phone jack but wider), you simply need an RJ45 to RJ45 Category 5 Crossover Cable. However, you do not need a "crossover" cable if you are connecting the two computers through an ethernet hub. In this case you just need two standard Category 5 patch cables to connect to the hub. A2Z sells both the ethernet NICs and the crossover/standard ethernet network cables to do this. Regarding the "software" side of connecting the computers, you will probably need to assign TCP/IP, NetBUI, or IPX networking protocols to your ethernet network adapter card (found in Start --> Settings --> Control Panel --> Network). If using the TCP/IP protocol on your network adapter, you will probably need to assign different IP addresses and the same subnet masks to the TCP/IP properties of each computer: Computer 1 could be IP 192.168.0.1 & subnet 255.255.255.0, and Computer 2 could be IP 192.168.0.2 & subnet 255.255.255.0. You might also need to type in the same Workgroup Name in the Identification tab.
