Normaly the jumper configurations are usually either printed on the back, or on the top of the drive. And drives can be configured in 2 ways: Drive Select or Cable Select. The drive jumpers are in the middle (between the connector for the cable and the power connector)

1. Cable Select :

   if we have 80-pin cables that time we use this. cable select automatically assigns slave/master based on the plug on the IDE cable the drive is plugged into.
