Hard Disk Drives
There are two IDE interface connectors on the system board. One system board IDE con-
nector provides a PCI-bus interface. The other system board IDE connector provides the
standard IDE interface. In configurations where the 3 1/2-inch hard disk drive is shipped
with the system unit the PCI-bus IDE connector is used.
When installing a second hard disk drive, use the open IDE connector on the cable coming
from the PCI-bus IDE connector system board IDE connector. The standard IDE connector
on the system board is used when adding a third and fourth IDE hard disk drive. A hard
disk controller board is not required. The IDE drives described in this section are thin-
height (1-inch x 3 1/2-inch) drives. See the 5 1/4-inch device installation instructions later in
this section.
