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. If your computer came with a CD-ROM drive, it 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 attached to
your computer, two on Local Bus connector 1, and
two on Local Bus connector 2.
•
If a hard disk shares the same connector with a drive
that requires a software device driver (such as a
CD-ROM drive), the hard disk must be set as the
master device.
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 J9 on the system
board.
•
Set the newly installed 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 (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 newly installed hard disk as a slave device if
another hard disk is already attached to the
connector.
