10) Primary IDE Connector (40-pin block): IDE1 (CN20)

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.

(11) Secondary IDE Connector (40-pin block): IDE2 (CN16)

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.
