Note: If you want to add another device, and your computer
does not come with a CD-ROM preinstalled, you will
need a second signal cable with three connectors. You
will need an 80-conductor ATA 66 signal cable if you
are replacing the existing signal cable or adding a
second hard disk. ATA 66 signal cables are
color-coded. The blue connector attaches to the system
board; the black connector attaches to the primary
device (also known as the master device), and the gray
middle connector attaches to the secondary device (also
known as the slave device).
If your computer comes with a CD-ROM drive, it will
have an ATA 66 signal cable. However, if you
installing a hard disk, you must change the switch
setting on the CD-ROM to secondary and change the
connector used for the CD-ROM drive to the gray
middle connector.
– The narrower signal cable has two connectors for attaching the
diskette drive to the diskette-drive connector on the system board.
Note: To locate connectors on the system board, see “Identifying parts on
the system board” on page 64.
The following are some important points to remember when connecting
power and signal cables to internal drives:
Ÿ
The drives that are preinstalled in your computer come with power and
signal cables attached. If you replace any drives, it is important to
remember which cable is attached to which drive.
Ÿ
When you install a drive, ensure that the drive connector at the end of
the signal cable is always connected to a drive; also, ensure that the
drive connector at the other end is connected to the system board. This
reduces electronic noise from the computer.
Ÿ
If two IDE devices are used on a single cable, one must be designated
as the primary or master device and the other as the secondary or
subordinate device; otherwise, some of the IDE devices might not be
recognized by the system. The primary or secondary designation is
determined by switch or jumper settings on each IDE device.
Ÿ
If two IDE devices are on a single cable, and only one is a hard disk
drive, the hard disk drive must be set as the master device.
Ÿ
If you have only one IDE device on a cable, it must be set as master.
