Have you done any research on this topic yourself? Basically, the steps are:

1. Plug in crossover cable to the NICs on both machines.
2. Assign an IP address to each machine. Since this is a private subnet, use the RFC1918 range (e.g. 10.x.x.x 192.168.x.x). For example, 192.168.0.1 and 192.168.0.2 with a subnet mask of 255.255.255.0 would be a good choice.
3. The machines should now be able to send packets back and forth over the crossover cable.

If you want more information, you're going to need to specify a lot more about what you want to do.

I think most network cards will auto-negotiate these days. In general though use a crossover cable through when connecting "similar type devices" and straight-through when connecting "dissimilar devices". I am not going to get into the technical details here, but in general:

Also bare in mind that most home routers are not really routers, meaning that you cannot assign different IP addresses to each of the ports that you see on them. They are three devices in one. The Ethernet ports that you see on your router are switch ports really, so you can use a straight-through cable to connect to those.

If your NICs won't auto-negotiate and you do not have a crossover cable, use a switch/home router and two straight-through cables. That should work.
