Ide Hard Drive Connector (Cn4); Connecting The Hard Drive - Aaeon PCM-4335 Manual

IDE hard drive connector (CN4)

You can attach one or two Enhanced Integrated Device Electron-
ics hard disk drives to the mainboard's internal controller. The
mainboard's IDE controller uses a PCI local-bus interface. This
advanced interface supports faster data transfer and allows the
IDE hard drive to exceed 528 MB.

Connecting the hard drive

Connecting drives is done in a daisy-chain fashion and requires
one of two cables, depending on the drive size. 1.8" and 2.5"
drives need a 1 x 44-pin to 2 x 44-pin flat-cable connector. 3.5"
drives use a 1 x 44-pin to 2 x 40-pin connect.
Wire number 1 on the cable is red or blue, and the other wires are
gray.
1. Connect one end of the cable to CN4. Make sure that the red
(or blue) wire corresponds to pin 1 on the connector, which is
labeled on the board (on the right side).
2. Plug the other end of the cable to the Enhanced IDE hard
drive, with pin 1on the cable corresponding to pin 1 on the
hard drives. (see your hard drive's documentation for the
location of the connector).
Connect a second drive as described above.
Unlike floppy drives, IDE hard drives can connect to either
end of the cable. If you install two drives, you will need to set
one as the master and one as the slave by using jumpers on the
drives. If you install just one drive, set it as the master.
