IDE hard drive connector (CN11)

The built-in Enhanced IDE (Integrated Device Electronics)
controller supports up to two IDE devices, including CD-ROM
drives, tape backup drives, a large hard disk drive and other IDE
devices. It also supports faster data transfer, PIO mode 3, mode 4,
and Ultra DMA 33 mode.
2.7.1 Connecting the hard drive
Connecting drives is done in a daisy-chain fashion and requires
one or two cables, depending on the drive size. All required cables
are included in your PCM-5820 Series package. 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 connector. However, the
required connectors are not included in the PCM-5820 Series
package.
Wire number 1 on the cable is red or blue, and the other wires are
gray.
1. Connect one end of the cable to CN11. 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 1 on the cable corresponding to pin 1 on the hard
drive. (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.
