If you are planning to boot from your existing HDD, then connect the new one as a slave and preferably to the middle connector of the 80-channel IDe cable (Grey colour), whereas the existing one to the Black connector at the other end.
The jumper settings for Master and Slave are printed on the HDD itself or on a Quick Installation guide if provided. Use those settings.
If you are using SATA HDDs then u'll have to configure it thru your BIOS, as from which HDD you wanna boot.
