Simple.  Your boot disk should have a jumper on it set to the "master"
position.  Your other disk should have a jumper set to the "slave"
position.  They might not be marked as such.  Consult your drive's
docs or contact the manufacturer.  I know that Seagate has an
automated information service on their phone number - just key in the
drive model (from a touch-tone phone) and listen for all the specs on
it.  Once you set the jumpers, you're done.

Don't assume that your old drive is already a "master" drive.  Some
drives have a third jumper position for "stand-alone" operation.  Your
new drive will almost certainly NOT be in the slave position.

Obviously, that isn't the jumper.  Some controllers don't have an LED
jumper.  Or you may have just found the wrong one.  On my controller,
the proper pins were the outer two on the 4-position connector.  I
don't know what you'll do with only a 2-pin plug, though.  Your
controller's documentation usually mentions this.

PS: by "documentation", I mean the little 3"x5" piece of paper that
most people ignore that comes with the card.
