Yep... It's just a jumper block. Sometimes those are there to change certain functions, like SATA 1.5 operation, or to limit the capacity of a drive for compatibility reasons. Usually on a SATA drive you don't need to worry about them.
And they don't actually make IDE to SATA cables that would use those jumpers. Usually SATA to IDE adapters will just default the drive to Master, or Cable Select, if you can hook it to an IDE cable.
