This connector connects to the next set of Master and Slave hard disks.  Follow the 
same procedure described for the primary IDE connector.  You may also configure two 
hard disks to be both Masters using one ribbon cable on the primary IDE connector and 
another ribbon cable on the secondary IDE connector.

  Two hard disks can be connected to each connector.  The first HDD is referred to as the 
“Master” and the second HDD is referred to as the “Slave”. 
  For performance issues, we strongly suggest you don’t install a CD-ROM or DVD-ROM 
drive on the same IDE channel as a hard disk.  Otherwise, the system performance on this 
channel may drop.
