You would need the drivers for the Ethernet port on your computer. These are usually installed by default though.
Sorry, your question is not that clear -
If your machine already has a ethernet socket, simply plug a cable in to it then the other end in to the router and it should be able to pick up all the settings via DHCP.
If you do not currently have an ethernet socket, you can buy a card quite cheap. Most of the off the shelf ones will be supported out the box in Windows XP. They will usually also have drivers included on a cd, or you can get updated ones from the chipset manufacturers site (e.g. Intel, Realtek e.t.c.).
Hope this helps, if it doesn't, please say in comments what the problem is.
