Plenty of information on Google about this but try .... On the backside of the new CD-RW, fit the jumper to position marked "slave". Fit the drive in a spare position. Make sure that your first CD drive has the jumper in the "master" position (I'm sure it is). Connect the ribbon cable from the motherboard first into the #1 drive and then the other connector on the same ribbon, connect to your new drive. Take care that they are all 'home'.
Connect up a second audio cable if you want the sound to work from this CD drive as well as the #1 drive. To do this you may have to locate a second plug position on the motherboard, some boards have only one but there's a way of overcoming this...let us know if you have problems with sound out.
Connect the power line to the new drive the same way as the #1 drive.
That's it. Fire up the PC and take note of what the monitor says to you !
