(7) Floppy drive Connector (34-pin block): FDD
This connector supports the provided floppy drive ribbon cable. After connecting the single
plug end to motherboard, connect the two plugs at other end to the floppy drives.
(8) Primary IDE Connector (40-pin block): IDE1
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.
