Overview
Your computer supports:
l Two hard drives (Your computer supports SCSI with an add-in controller, IDE, and Serial ATA.)
l One floppy drive
l Two CD or DVD drives
IDE Drive Addressing
When you connect two IDE devices to a single IDE interface cable and configure them for the cable select setting, the device attached to the last connector on
the interface cable is the primary (master) or boot device (drive 0), and the device attached to the middle connector on the interface cable is the secondary
(slave) device (drive 1). See the drive documentation in your upgrade kit for information on configuring devices for the cable select setting.
Since cable select is the default setting, any additional drives that are installed do not need to be set as a primary or secondary drive.
Your computer supports up to two IDE devices. Hard drives should be connected to the connector labeled "IDE1," and CD/DVD drives should be connected to
the connector labeled "IDE2."
Connect serial ATA drives to the connectors labeled "SATA_0" or "SATA_1."
Connecting Drive Cables
When you install a drive, you connect two cables—a DC power cable and an interface cable—to the back of the drive.
