1-18 Technical Information
All systems ship with one internal 3 1/2-inch hard disk (1-inch high, thin-height) installed
behind the front panel in the bottom slot in the drive cage. The three-connector hard disk
drive cable plugs into the primary connector on the system board. An optional second hard
drive can be connected to the middle connector on the primary IDE cable. A third hard
drive (in a 5 1/4-inch accessible slot) can be connected to the middle connector on the
secondary IDE cable. In multimedia configurations, the secondary IDE cable connects the
CD-ROM reader to the system board. The standard hard disk drive is set as the master
device on the primary IDE/PCI port (see Figure Section 1-3). Use the Storage Device
Installation procedures in Section 3 when installing optional devices.

NOTE:
When ATA and ATAPI devices are
installed on the same channel, primary or
secondary, the ATA device must be configured
as the master.
SCSI Hard Disk
All SCSI configuration systems ship with one internal 3 1/2-inch hard disk (1-inch high,
thin-height) installed behind the front panel in the bottom slot in the drive cage. A three-
connector hard disk drive cable connects the SCSI hard disk to the Ultra Wide SCSI
adapter board. An optional second hard drive can be connected to the middle connector on
the hard disk drive cable. Before installing additional SCSI devices, review the basic SCSI
concepts provided in “SCSI Devices” in Section 3, Installing Options.
