Guidelines For Connecting Ide/Ata Signal Cables - IBM Aptiva Handbook

Guidelines for connecting
IDE/ATA signal cables
Your system board has two connectors for attaching
IDE/ATA signal cables, but you can install two IDE/ATA
drives to each of these connectors if you have the
proper cables. When two drives are attached to one
connector, one drive must be the master device, and the
other the slave device. Jumper settings on the drives
determine which drive is the master and which is the
slave.
The hard disk that came installed in your computer is
attached to Local Bus connector 1 and is set as a master
device. The CD-ROM drive that came installed in your
tower is attached to Local Bus connector 2 and is set as
a master device.
These are the general guidelines for IDE/ATA signal
cable connections:
•
If only one drive is attached to a connector, it must
be set as a master device.
•
On each connector, there can be only one drive set
as the master device and one drive set as the slave
device.
•
A maximum of four IDE drives can be installed in
your tower, two on Local Bus connector 1, and two
on Local Bus connector 2.
•
If a hard disk or a Zip drive shares the same
connector with a drive that requires a software
device driver (such as a CD-ROM drive), the hard
disk or Zip drive must be set as the master device.
For instructions on setting a new drive as a master or
slave device, see the documentation that came with the
drive.
If you are installing a drive on Local Bus connector 1,
follow these guidelines:
•
Attach the signal cable from the drive to Local Bus
connector 1, which is labeled J5 on the system
board.
•
Set the new drive as a master device if one of these
conditions exists:
–
The new drive is the only drive attached to the
connector.
–
Another drive that is not a hard disk drive or a
Zip drive (such as a CD-ROM) is already attached
to the connector. Set the drive that is already
attached to the connector as the slave device.
Jumpers for setting CD-ROM drives as master or
slave devices are typically located at the back of
the drive.
•
Set the new hard disk or Zip drive as a slave device if
another hard disk or Zip drive is already attached to
the connector.
