Adding Mass Storage Devices
Before adding mass storage devices to your computer, review the following
installation guidelines:
1. Refer to the manufacturer's instructions for your device to determine if
switches or jumper settings need to be set or installed on the device. Set all
switches and jumpers accordingly before installing the device.
2. Select an available drive bay and then install the device as instructed in the
following sections of this manual.
3. Connect the device to an appropriate interface ribbon cable connector as
described in the following sections. Also consider the following cabling
guidelines:
−
Your computer has two Enhanced IDE (EIDE) drive interface
connections labeled "primary" and "secondary" located on the
computer backplane.
−
Each IDE drive interface connector supports a maximum of two IDE
devices.
−
If only one IDE device is connected to the primary or secondary IDE
interface, then the IDE device must be attached to the outermost
ribbon cable connector.
−
When adding a second IDE hard disk drive to the primary IDE
interface, configure the drive for "slave" operation.
