One spot is usually labled "MA" or "MS". Putting a jumper on that makes the drive the master. Another jumper spot will probably be labeled "SL" and putting the jumper there will make the drive the slave. There's often a third spot, labeled "CS" (for "cable select"). Theoretically, you can put a jumper on there and the drive will figure out if it's to be a master or a slave.
Just to add something.. Some drives dont have anything marked at all close to the jumpers (I'm looking at a seagate disk right now), but they *usually* have an sticker over the disk with the meaning of the possible jumper placements.
