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.
Hard Disk Drive Settings
The following IDE hard disk drives are available for installation in the system. Systems
come with a hard disk drive preinstalled in the computer. Specifications for all the optional
IDE hard drives are given in Appendix B, Specifications. Jumpers for the drives are set for
single drive configurations. Jumper settings and their locations are shown in
Figure Section 3-13 and Figure Section 3-15.
