IEEE 1394

IEEE 1394 is a digital interface that can move large amounts of data between computers and peripheral devices. IEEE 1394 is ideal for use with multimedia devices because it speeds the transfer of data and large files, which enables a computer to connect directly to devices such as digital video cameras.

NOTE: The connector can accept 4-pin IEEE 1394 devices with the use of an adapter.

Your computer may have an optional front IEEE 1394 connector (see "Front View of the Computer" on page 65). This connector is only available if you purchased an add-in card that uses IEEE 1394. To purchase a card, contact Dell.

Hyper-Threading

Hyper-Threading is an Intel® technology that can enhance overall computer performance by allowing one physical processor to function as two logical processors, capable of performing certain tasks simultaneously. It is recommended that you use the Microsoft® Windows® XP Service Pack 1 (SP1) or later operating system because Windows XP is optimized to take advantage of Hyper-Threading technology. While many programs can benefit from Hyper-Threading, some programs have not been optimized for Hyper-Threading and may require an update from the software manufacturer. Contact the software manufacturer for updates and information about using Hyper-Threading with your software.

To determine if your computer is using Hyper-Threading technology:

1Click the Start button, right-click My Computer, and then click Properties.

2Click Hardware and click Device Manager.

3In the Device Manager window, click the plus (+) sign next to Processors. If Hyper-Threading is enabled, the processor is listed twice.

You can enable or disable Hyper-Threading through system setup. For more information on accessing system setup, see page 114. For more information on Hyper-Threading, search the Knowledge Base on the Dell Support website at support.dell.com.
