Hard Disk Drive Options
There are two fast PCI-bus enhanced IDE interface connectors on the system board. Each
connector (J30, J32) supports two IDE devices. In addition, the system board contains one
SCSI-2 slot (J14) capable of supporting up to five internal and seven external SCSI-2
devices.
When installing a second IDE hard disk drive, use the open IDE connector on the cable
coming from the PCI-bus IDE connector on the system board. 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 that mount in a 5 1/4-inch bracket. See “5 1/4-Inch Device Installation” later in
this section for installation procedures.
Hard Disk Drive Settings
The following subsections provide configuration settings for optional IDE and SCSI-2
storage options.
IDE Hard Disk Settings
A 3/12-inch x 1-inch, 1-GB IDE hard disk drive is available for installation in the system.
IDE hard drive specifications are given in Appendix A, Specifications. Jumpers for the
drive are set for single drive configurations. Jumper settings and locations for the 1-GB
IDE hard disk drive are shown in Figure Section 3-17.
