For more information on installing an internal peripheral device, refer to the documentation
delivered with the peripheral device, the information posted on the device, or the appropriate
System Board Manual.

Adding SCSI Peripheral Devices

On a system equipped with a Small Computer System Interface (SCSI) adapter and internal
SCSI disk drives, a SCSI adapter board is installed in a Peripheral Component Interconnect
(PCI) expansion board slot. This adapter is connected by internal cabling to any internal SCSI
hard disk drives and to the disk access LED on the front panel of the system. You can connect
external and internal SCSI-1 and SCSI-2 peripheral devices to this adapter.
NOTE When adding peripheral devices to a system with a SCSI boot drive, add only SCSI devices.
If you purchase a SCSI adapter for installation in a system equipped with internal Integrated
Device Electronics (IDE) or Enhanced IDE (EIDE) disk drives, you cannot connect internal
SCSI peripheral devices to this adapter.
If you need the driver for the system's SCSI adapter -- for example, if you must re-install the
operating system and associated system software -- you can find it on the operating system
CD-ROM delivered with the system.
For information on configuring the system's BIOS on a SCSI system, refer to Chapter 3,
"Configuring the System." For information on booting from an external SCSI disk drive, refer
to Chapter 4, "Operating Notes." For information on connecting peripheral devices to the
SCSI adapter, refer to the documentation delivered with the adapter.
NOTE Make sure the last device on a chain of external SCSI devices has an active SCSI terminator
attached to the open SCSI port.

Using System Resources

When you add an expansion board or a peripheral device to the computer, it may need to use
system resources to ensure proper operation. The following sections list commonly used
system resources. Refer to the documentation delivered with an expansion board or a
peripheral device for instructions on how to use these resources, and to the appropriate System
Board Manual for more system resource information.
