## Installing the Driver Software

When Windows first starts after a new hardware device (such as a Broadcom Gigabit Ethernet controller) has been installed, or after the existing device driver has been removed, the operating system automatically detects the new hardware and prompts you to install the driver software for that device.

| Note: A network device driver must be installed before the Broadcom Gigabit Ethernet controller can be used with your Windows system.

### Using the Driver Installer

1. If the Found New Hardware Wizard appears, click Cancel.
2. Open the folder that contains the Setup.exe file and then double-click Setup.exe.
3. Click Next, and then click Yes to agree to the License Agreement.

### Using the Found New Hardware Wizard

When the Found New Hardware Wizard appears, follow the instructions provided by the wizard.

## Updating the Driver Software

To update the driver software

1. Start Windows and log on. You must have network administrator permissions to update the driver software.
2. In Control Panel, click System to view System Properties.
3. Click the Hardware tab, and then click Device Manager.
4. Right-click the name of the Broadcom Gigabit Ethernet controller and click Update Driver.
5. Follow the instructions provided by the Hardware Update Wizard.

## Viewing or Changing the Properties of the Controller

To view or change the properties of the Broadcom Gigabit Ethernet controller

1. In Control Panel, double-click System to display System Properties.
2. Click the Hardware tab, then click Device Manager.
3. Double-click Network Adapters.
4. Right-click the name of the Broadcom Gigabit Ethernet controller of interest and click Properties.
5. Click the Advanced tab.

6. Click the property you want to change, and then change the value by clicking an item in the Value list or by typing a new value, as appropriate (selection options are different for different properties).

The available properties and their respective settings are described below.

802.1p QoS. The 802.1p QoS property enables quality of service—an IEEE specification that treats different types of network traffic differently to ensure required levels or reliability and latency according to the type of traffic. This property is disabled by default.

Checksum Offload. Normally the Checksum Offload function is computed by the protocol stack. By selecting one of the Checksum Offload properties, the checksum can be computed by the controller.

> Rx TCP/IP Checksum. Enables receive TCP, IP, and UDP checksum offloading.

> Tx TCP/IP Checksum. Enables transmit TCP, IP, and UDP checksum offloading.

> Tx/Rx TCP/IP Checksum (default). Enables transmit and receive TCP, IP, and UDP checksum offloading.

Ethernet@Wirespeed. Ethernet@Wirespeed enables a 1000BASE-T Ethernet adapter to establish a link at a lower speed when only 2 pairs of wires are available in the cabling plant. By default, the controller is set to Enable.

| Note: Not all Broadcom Gigabit Ethernet controllers support Ethernet@Wirespeed. Contact the supplier from whom you purchased this product if you have questions about the availability of this support.

Flow Control. The Flow Control property allows you to enable or disable the receipt or transmission of PAUSE frames. PAUSE frames enable the controller and the switch to control the transmit rate. The side that is receiving the PAUSE frame momentarily stops transmitting.

> Auto (default). PAUSE frame receipt and transmission are optimized.

> Disable. PAUSE frame receipt and transmission are disabled.

> Rx PAUSE. PAUSE frame receipt are enabled.

> Rx/Tx PAUSE. PAUSE frame receipt and transmission is enabled.

> Tx PAUSE. PAUSE frame transmission is enabled.

Jumbo Mtu. The Jumbo Mtu property allows the controller to transmit and receive oversized Ethernet frames that are greater than 1514 bytes but less than 9000 bytes in length. Note that this property requires a switch that is able to process large frames. Jumbo Mtu is set at 1500 bytes by default. You can increase the size of the received frames in 500-byte increments.

| Note: Jumbo Mtu is only supported on the BCM5701/BCM5702/BCM5703/BCM5704 controllers.

Large Send Offload. Normally the TCP segmentation is done by the protocol stack. By enabling the Large Send Offload property, the TCP segmentation can be done by the Broadcom Gigabit Ethernet controller.

> Disable. Disables large send offloading.

> Enable (default). Enables large send offloading.

| Note: Large Send Offload is available only in the Windows XP environment.

Speed & Duplex. The Speed & Duplex property allows the user to set the connection speed to the network and mode. Note that Full-Duplex mode allows the controller to transmit and receive network data simultaneously.

> 10 Mb Full. Sets the speed at 10 Mbit/s and mode to Full-Duplex.

> 10 Mb Half. Sets the speed at 10 Mbit/s and mode to Half-Duplex.

> 100 Mb Full. Sets the speed at 100 Mbit/s and mode to Full-Duplex.

> 100 Mb Half. Sets the speed at 100 Mbit/s and mode to Half-Duplex.

> Auto (default). Sets the speed and mode for optimum network connection (recommended).

| Notes: Auto is the recommended setting. This setting allows the controller to dynamically detect the line speed of the network. Whenever the network capability changes, the controller automatically detects and adjusts to the new line speed and duplex mode. A speed of 1 Gbit/s is enabled by selecting Auto, when that speed is supported. 10 Mb Half and 100 Mb Half settings force the controller to connect to the network in Half-Duplex mode. Note that the controller may not function if the network is not configured to operate at the same mode. 10 Mb Full and 100 Mb Full settings force the controller to connect to the network in Full-Duplex mode. The controller may not function if the network is not configured to operate at the same mode.

Wake Up Capabilities. The Wake Up Capabilities property allows you to set the Broadcom Gigabit Ethernet controller to wake up from a low-power mode when it receives a network wake-up frame. Two types of wake-up frames are possible: Magic Packet™ and Wake Up Frame.

> Both (default). Selects both Magic Packet and Wake Up Frame as wake-up frames.

> Magic Packet. Selects Magic Packet as the wake-up frame.

> None. Selects no wake-up frame.

> Wake Up Frame. Selects Wake Up Frame as the wake-up frame, and allows the controller to wake the system when events such as a ping or an Address Resolution Protocol (ARP) request are received.

WOL Speed. The WOL Speed property allows the user to select the speed at which the controller connects to the network during Wake on LAN mode.

> 10 Mb. Sets the speed at 10 Mbit/s.

> 100Mb. Sets the speed at 100 Mbit/s.

> Auto (default). Sets the speed for optimum network connection.

When you have finished viewing or changing the properties of the controller, click OK to accept the settings.

If you are prompted to restart your computer, click OK.

| Note: It is not necessary to restart the computer for new controller properties to take effect. It is recommended, however, to re-initialize all registers.

Verify that the controller port LEDs operate as described in Table 1 in Introduction.

## Setting Power Management Options

You can set Power Management options to allow the operating system to turn off the controller to save power or to allow the controller to wake up the computer. If the device is busy doing something (servicing a call, for example), however, the operating system will not shut down the device. The operating system attempts to shut down every possible device only when the computer attempts to go into hibernation. To have the controller stay on at all times, do not click the Allow the computer to turn off the device to save power check box.

| Notes: To enable Wake on LAN (WOL) when the computer is on standby, select the Allow the device to bring the computer out of standby check box. For WOL to operate properly, the Wake on LAN feature must be enabled on the controller. For instructions on how to enable WOL, see DOS Diagnostics. If you select Only allow management stations to bring the computer out of standby, the computer can be brought out of standby only by Magic Packet, regardless of the settings in Wake Up Capabilities.

## Removing the Driver Software

1. In Control Panel, double-click Add/Remove Programs.
2. Click Broadcom Driver Installer, and then click Change/Remove.
3. Click OK to remove the Broadcom Network Device Driver.
