LegacySelect Technology Control

LegacySelect technology control offers legacy-full, legacy-reduced, or legacy-free solutions based on common platforms, hard-drive images, and help desk procedures. Control is provided to the administrator through system setup, Dell OpenManage™ IT Assistant, or Dell custom-factory integration.

LegacySelect allows administrators to electronically activate or deactivate connectors and media devices that include serial and USB connectors, a parallel connector, a floppy drive, PCI slots, and a PS/2 mouse. Connectors and media devices that are deactivated make resources available. You must restart the computer to effect the changes.


Manageability

Alert Standard Format

ASF is a DMTF management standard that specifies "pre-operating system" or "operating system-absent" alerting techniques. The standard is designed to generate an alert on potential security and fault conditions when the operating system is in a sleep mode or the system is turned off. ASF is designed to supersede previous operating-system-absent alerting technologies.

Your computer supports the following ASF version 1.03 and 2.0 alerts and remote capabilities:

Alert

Description

Chassis: Chassis Intrusion – Physical Security Violation/Chassis Intrusion – Physical Security Violation Event Cleared

The computer chassis with the chassis intrusion feature (optional on some computers) installed and enabled has been opened or the chassis intrusion alert has been cleared.

CPU: Emergency Shutdown Event

The processor temperature is too hot and the power supply has shut down.

Cooling Device: Generic Critical Fan Failure/Generic Critical Fan Failure Cleared

The fan speed (rpm) is out of limits or the fan speed (rpm) problem has been resolved.

Temperature: Generic Critical Temperature Problem/Generic Critical Temperature Problem Cleared

The computer temperature is out of limits or the computer temperature problem has been resolved.

Battery Low

The system battery has reached a voltage of 2.2 V or lower.

ASF allows Remote Management and Control Protocol (RMCP) messages to be exchanged between a remote management console and a client computer that is in a "pre-operating system" or "operating system-absent" state. RMCP messages can be sent to instruct a client computer to start up, shut down, or restart.

For more information about Dell's ASF implementation, see the ASF User's Guide and the ASF Administrator's Guide, which are available on the Dell Support website at support.dell.com.

Hyper-Threading and Dual-Core Technology

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. Dual-Core is an Intel technology in which two physical computational units exist inside a single CPU package, thereby increasing computing efficiency and multi-tasking ability. It is recommended that you use the Microsoft® Windows® XP Service Pack 1 (SP1) or higher operating system because Windows XP is optimized to take advantage of Hyper-Threading technology.

While many programs can benefit from Hyper-Threading and dual-core technology, some programs may have not been optimized for them and may require an update from the software manufacturer. Contact the software manufacturer for updates and information about using Hyper-Threading or dual-core technology with your software. To determine if your computer is using Hyper-Threading technology, check the system setup option for Hyper-Threading under the Performance tab (see System Setup).


Power Management

Your computer can be set to use less power when you are not working. You control the power usage through the operating system installed on your computer and certain option settings in system setup (see System Setup). These periods of reduced power are called "sleep modes."

NOTE: If your system has a card in the PCI Express x16 slot and you add a peripheral that does not support suspend (S3), you system will not be able to enter stand-by.
NOTE: All components installed in the computer must support the hibernate and/or standby mode feature(s) and have the appropriate drivers loaded to enter either of these sleep modes. For more information, see the manufacturer's documentation for each component.

The following table lists the sleep modes and the methods you can use to wake the computer from each mode.
