11. Primary IDE Connector (40-pine block): IDE1
This connector supports the provided IDE hard disk ribbon cable, After connecting the
single plug end to motherboard, connect the two plugs at other end to your hard
disk(s). If you install two hard disks, you must configure the second drive to Slave
mode by setting its jumpers accordingly. Please refer to the documentation of your
hard disk for the jumper settings.
12. Secondary IDE Connector (40-pin block): IDE2
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 Master using one ribbon cable on the primary IDE connector
and another ribbon cable in 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.
