Connecting drives is done in a daisy-chain fashion and requires a
1 x 44-pin to 2 x 44-pin flat-cable connector.
Wire number 1 on the cable is red or blue, and the other wires are
gray.
1. Connect one end of the cable to CN3. 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 into 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.
