Click the Start button, right-click My Computer, and then click Properties.2. Click Hardware and click Device Manager.3. In the Device Manager window, click the plus (+) sign next to the processor type. IfHyper-Threading is enabled, the processor is listed twice.You can enable or disable Hyper-Threading through system setup. For more information, see "System Setup Options."IEEE 1394aIEEE 1394a is a digital interface that can move large amounts of data between computers and peripheral devices. IEEE 1394ais ideal for use with multimedia devices because it speeds the transfer of data and large files, which enables a computer toconnect directly to devices such as digital video cameras.NOTE: The connector can accept six-pin IEEE 1394a devices with the use of an adapter.Your computer provides a standard IEEE 1394a connector on both the front and back panels (see "Your Dell Precision™ 670Computer" or "Your Dell Precision™ 470 Computer"). The front connector on the Dell Precision 470 computer is available withan optional card.U320 SCSI ControllerThe U320 SCSI controller is PCI-X based and operates in a low voltage differential (LVD) mode while running at U320 (320MBps) speeds. The bus is backward compatible and can run at U160 (160 MBps), Ultra2 (80 MBps), and Ultra (40 MBps)speeds.If single-ended (SE) devices are connected to the same bus as the LVD devices (such as U320, U160, or Ultra2), the SCSIbus operates in SE mode and runs at a maximum of Ultra (40 MBps) speed.For more information about installing a SCSI device and SCSI ID settings for your Dell Precision 670 computer, see "Drivesfor the Dell Precision 670 Computer" and for your Dell Precision 470 computer, see "Drives for the Dell Precision 470Computer."NOTE: Due to resource constraints, you can not install more than one SCSI controller, regardless of make or model.Power ManagementYour computer can be set to use less power when you are not working. You control the power usage through the operatingsystem installed on your computer and certain option settings in system setup. These periods of reduced power are called"sleep states:"Standby — In this sleep state, power is reduced or turned off for most components, including the cooling fans.However, system memory remains active.NOTE: All components installed in the computer must support this feature and have the appropriate drivers loaded toenter standby mode. For more information, see the manufacturer's documentation for each component.Hibernate — This sleep state reduces power consumption to a minimum by writing all data in system memory to ahard drive and then removing system power. Waking up from this state restarts the computer, and the memorycontents are restored. Operation then resumes where the computer left off when it entered the hibernation state.NOTE: All components installed in the computer must support this feature and have the appropriate drivers loaded toenter hibernation. For more information, see the manufacturer's documentation for each component.Shutdown — This sleep state removes all power from the computer except a small auxiliary amount. As long as the
