Hard Disk Drives
There are two IDE interface connectors on the system board supporting up to four IDE de-
vices. One system board IDE connector provides a Fast local bus interface. The other sys-
tem board IDE connector provides the standard IDE interface. The 3 1/2-inch hard disk
drive shipped with the system unit uses the Fast IDE local bus connector. The standard IDE
connector on the system board is used by the CD-ROM reader in the multimedia systems.
When installing a second hard disk drive, use the open IDE connector on the cable coming
from the Fast local bus system board IDE connector. A hard disk controller board is not re-
quired. The IDE drives described in this section are thin-height (1-inch x 3 1/2-inch)
drives.
