Hi when t says jumpered he means the jumper switch settings. On the back of the hard drive next to where you plug the IDE cable and power cable in there are a set of small brass pins with one or two small black plastic covered "joiners" pushed down over some of them making certain connections, these are the jumpers. the settings may be printed on the housing of the hard drive if your lucky, if not hunt them down on tut internet. Also its better to have your boot drive on the end of the IDE cable and the slave on the connector in the middle, that's if they are sharing a cable.
hope that's of help.
