3 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
1
attached to Local Bus connector 1 and is set as a master
2
device. If your computer came with a CD-ROM drive, it is
3
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.
