## Installing the Drivers

You can install drivers for Intel adapters using the Found New Hardware Wizard or the Intel® PRO Intelligent Installer.

| NOTE: Advanced features require Service Pack 6a. NOTE: When installing adapters on a Windows NT* system that does not have any other adapters installed, you must install Networking support. To successfully install Networking and the adapter drivers, you can either: Copy the required NT 4.0 Networking files to the hard drive and use the Intel CD to install the adapter driver, or Use the NT 4.0 CD to install Networking and create setup disks to complete driver installation. To create setup disks, click Create Install Disk from the Autorun screen.

Installation with the Intel® PRO Intelligent Installer

First, install the network adapter in the computer, connect the cable, plug in the power cord and start the computer. Insert the Intel CD in the CD-ROM drive. Click Install Base Drivers Only to install the drivers and Intel® PROSet II. When prompted, restart the computer.

Installation with the Network Setup Utility

1. Click the Network icon in the Control Panel.

2. Go to the Adapters tab and click Add.

3. Don't select an Intel adapter from the list. Instead, click Have Disk.

4. Enter the path to your Intel CD or installer package, in the "Install from Disk" window and click OK.

5. Follow the instructions to install the drivers. When the adapter is added, it appears in the Network adapters list.

6. Click OK and then Close. When prompted, restart Windows NT.

| NOTE: After restarting your computer, you can use Intel® PROSet to configure advanced settings and set up teams, VLANs, and other features. See Using Intel PROSet for more information. For NT 4.0, Intel PROSet II is automatically installed with the Intel PRO/1000 base driver.

### Installing Multiple Adapters

You can install drivers for multiple adapters using the Found New Hardware Wizard or the Intel PRO Intelligent Installer.

- When you use the Install Base Driver Only option in the Intel PRO Intelligent Installer, all adapter drivers required by the system are installed automatically.

## Updating the Drivers

You can update drivers using either the Update Device Driver wizard or the Intel CD.

#### Update drivers with the Intel CD

You can update drivers using the autorun program on the Intel CD.

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

2. Click Install Base Drivers Only.

Intel adapter drivers automatically update.

#### Update drivers in the Network Properties window

1. Click the Network icon in the Control Panel.

2. Go to the Adapters tab.

3. Select the adapter from the adapter list and click the Update button.

4. Enter the path to your update CD (or software package) on the "Windows NT Setup" window and click OK.

5. Follow the instructions to update the drivers.

## Setting Up Jumbo Frames

To configure jumbo frames on a PRO/1000 server adapter, start Intel PROSet II and click the Advanced tab. Select Jumbo Frames from the list of functions on the left and configure it to "Enabled" in the value field. You must set your desired packet size (based on network capability). Common sizes are displayed, but the entire range (1,500-16,000 bytes) is available. All equipment on the network must also support the larger frame size and the switch should be set 8 bytes larger than what is specified in Intel PROSet.

Also see the discussion of Jumbo Frames in Other Advanced Features.

## Removing Adapters

| NOTE: Before removing adapters, first remove teams and VLANs in Intel PROSet and then uninstall (or disable) the Intel network drivers using the Network control panel. If you remove the physical adapter prior to removing it from the Network control panel, the adapter will not be removed from the OS and will remain as a phantom adapter.

After ensuring the adapter is not part of a team, remove the adapter from the Network Control Panel:

1. Double-click the Network icon in the Control Panel.

2. Click the Adapters tab and highlight the adapter to remove.

3. Click the Remove button, then click OK.

| NOTE: If you are removing the last adapter to use the Intel network driver, the installer program will ask if you want to remove Intel PROSet. Click Yes.

Then remove the physical adapter:

1. Shut-down the computer and unplug the power cable.

2. Disconnect the network cable from the adapter.

3. Open the case and remove the adapter.

4. Close the case.

5. Reattach the power cable, and power-up the computer.

## Troubleshooting

If Windows NT reports an error or you can’t connect to the network, try the suggestions here first, then turn to Troubleshooting and FAQs.

- Make sure that you use the drivers for this adapter. Drivers are located on the Intel CD and on the web at http://support.intel.com.

- In your computer’s BIOS settings, make sure "Plug and Play OS?" is set to "NO".

- Make sure the drivers are loaded and the protocols are bound. Check the Settings in the Control Panel’s Network/Bindings dialog box.

- Check the Windows NT Event Viewer for error messages.

- If you are attaching to a NetWare network, check your frame type and verify that NetWare client or server software has been installed.

- Test the adapter with the Intel PROSet II configuration utility that was installed on your system when you installed the adapter. To start Intel PROSet II, double-click the Intel PROSet II icon in the Windows Control Panel. To run diagnostics, select the adapter and click the Diagnostics tab, then click Run Tests. For additional information, click Help in the Intel PROSet II window.
