Hard Disk Drives

There are two IDE interface connectors on the system board. One system board IDE con-
nector provides a Fast local bus interface. The other system 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 desktop systems and is not used in minitower 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.
See the 5 1/4-inch device installation instructions later in this section.

The following IDE hard disk drives are available for installation in the system. Systems

Figure Section 3-13 and Figure Section 3-15.
