# Windows 2000 and Windows XP Installation

- Windows 2000
- Windows XP

## Windows* 2000

| NOTE: When you insert the adapter, Windows 2000 detects the controllers on the adapter and automatically installs drivers. Although these drivers provide basic LAN and modem functionality, you should update the drivers as described below.

| NOTE: If Windows 2000 is enabled for IPSec encryption, the PRO/100 S adapter automatically offloads the intensive encryption and authentication functions onto the IPSec co-processor on the adapter. (The PRO/100 Mobile Adapter driver registers with the operating system to automatically enable this function.) The result is an increase in throughput and a decrease in CPU utilization.
| NOTE: In order to enable 3DES encryption in Windows 2000, you must install the Windows 2000 High Encryption Pack. (By default, Windows 2000 ships with DES support only). This pack is available at the Microsoft download page. Double authentication-based security associations will not be offloaded. If you are using an Intel PRO/100 S adapter, note that Windows 2000 doesn't offload fragmented IP traffic to the adapter. Tunnel mode processing is off-loaded to the encryption co-processor but is not supported by Intel Packet Protect.

#### Installation with the Intel® PRO Intelligent Installer

The Intel PRO Intelligent Installer enables you to install adapter drivers, configuration utilities, and other add-on components for Intel adapters. The Installer supports Windows* 98, 2000, XP, and NT* 4.0. For Windows 95, see the Win95 folder on the CD-ROM shipped with your Intel® PRO/100 adapter.

For directions on installing drivers using the Installer, see Run the Installer.

#### Installation with the Found New Hardware Wizard

After you install the network adapter in the computer, connect the cable, plug in the power cord and start the computer, Windows displays the Found New Hardware dialog box and starts the Found New Hardware Wizard.

Using the Wizard, follow this procedure to install the correct driver.

1. Insert the Intel CD in the CD-ROM drive.
   The CD autorun program starts. Close this window.

2. On the Wizard Welcome screen, click Next to start.

3. On the next screen, choose the Search option and click Next.

4. Click the CD-ROM box on the Locate Driver screen and make sure it is the only box selected. Then, click Next.

5. After a few moments, the Search Results indicates a driver was found on the CD. Click Next to continue.

6. The necessary files are copied to your computer.
   The wizard displays a Completed message. Click Finish.

7. Install Intel PROSet to configure and test the adapter. See Run the Installer (if you have a modem, use the Custom setting as described in the next step).

8. For your PRO/100 Combo Mobile Adapter, be sure the Drivers component, the Intel® PROSet II Wired Component, and the Intel® PRO/100 Mobile Modem Utilities Configuration Tool component are all configured for installation on the local drive. (After installation, the modem utilities will be accessible using Start > Programs > Intel(R) PRO-100 Mobile Modem Utilities.)

9. For most networks, you will need to configure properties for your protocols, computer identification, and preferred servers. Contact your network administrator for details if you need assistance.

10. Use PROSet II to configure advanced settings and set up teams, VLANs, and other features. See the PROSet II Help features for more instructions.

11. Use your communications software to configure and operate the modem. For instruction on how to use modem AT commands, see Modem Information.

## Windows* XP

| NOTE: If you are upgrading from a prior version of Windows and you have Intel PROSet software installed, it will be deleted in the process. You will need to reinstall Intel PROSet software as described in this procedure.
