That's the old Cable Select configuration used with 40-conductor 
cables defined in ATA-4 and earlier specifications.

That's the Cable Select setup for ATA-5 and later, used with 
80-conductor cables.

If you set master/slave with jumpers instead of using CS the 
master/slave location shouldn't matter if you have two drives, 
but if you have only one drive it should be at the end of the 
cable to reduce electrical interference.
