Windows® 2000 Driver Software: Broadcom NetXtreme™ Gigabit Ethernet Adapter User's Guide

This chapter provides the following information:

Installing the Driver Software

NOTE – The Broadcom NetXtreme™ Gigabit Ethernet Adapter must be physically installed in your system prior to installing the driver software. See Installing the Hardware for details.

When the Windows 2000 system first boots up after installing a new hardware device, such as a Gigabit Ethernet Adapter, the system automatically detects the new hardware and prompts you to install the driver software for that device.

A network device driver must be installed before the Gigabit Ethernet Adapter can be used with your Windows 2000 system.

Installing the Adapter Software

To install the adapter software for Windows 2000, do the following

NOTE – Before beginning this procedure, verify that the Windows 2000 system has been upgraded to the latest version with the latest service pack applied.

When updating the adapter software on existing Broadcom devices, the Advanced Property settings may not be updated unless the existing Broadcom device is removed by following the instructions in the Removing the Driver Software section. You must then perform a scan for hardware changes in the device manager, followed by re-installing the Broadcom device with the current adapter software as described in the Installing the Driver Software section. Prior to uninstalling the Broadcom device, ensure to capture all Advanced Property settings because the parameters will be lost.

Start your Windows 2000 system and log in. You must have Administrator privileges to install the driver software.

When you boot up the Windows 2000 system after installing the adapter card, a series of Found New Hardware Wizard windows are displayed.

In the Install Hardware Device Drivers window, click Search for a suitable driver for my device (recommended), then click Next.

In the Locate Driver Files window, select the applicable search location check boxes, then click Next.
When prompted, insert the media to be searched into your CD-ROM drive, type the path to the driver, and select OK.
Example: e:\
Where "e:" is the designation of the CD-ROM drive on your system.

In the Driver Files Search Results window, verify that the correct path to the driver software is shown, then click Next.

NOTE – If the Insert Disk window appears, do not insert the Windows 2000 disk:

Some early versions of Windows 2000 may display a spurious message requesting you to insert the Windows 2000 disk. If this occurs, leave the driver installation media in the drive and click OK. If asked to specify the location of the Windows 2000 CD-ROM instead, click Browse (don’t use the text entry field) and locate the path to the Gigabit Ethernet drivers that was specified above.

Once installation of the driver software is complete, you are ready to modify configuration parameters.

Modifying Configuration Parameters

Although the default values should be appropriate in most cases, you may change any of the available options to meet the requirements of your specific system. Once the adapter driver software has been installed, you can use this procedure to verify or change the following adapter properties:

802.1p QOS
Checksum Offload
Ethernet@WireSpeed™
Flow Control
Jumbo Mtu
Locally Administered Address
Speed & Duplex
Wake Up Capabilities
WOL Speed

Driver Properties Advanced Tab

To configure the adapter parameters, bring up the Driver Properties Advanced tab as follows:

On the Desktop, right-click the My Computer icon and select the Properties option from the pop-up menu. The System Properties window displays.
Click the Hardware tab and then click Device Manager. The Device Manager window displays.
Scroll down the list of hardware devices to Network Adapters. Click the plus (+) to the left of the icon to display the list of adapters currently configured.
Double-click the Gigabit Ethernet Adapter you want to configure. The Gigabit Ethernet Properties window displays, showing the General tab.
Click the Advanced tab. A window showing the list of configurable properties (and default values) for the adapter displays.
Change the operating parameters as desired. To change adapter operating parameters listed under the Advanced tab, click on the options listed under Property and then use the pull-down window under Value to change the default or assigned value.

802.1p QOS Parameter

The 802.1p QOS parameter is a standard that enables Quality of Service (QOS). It is responsible for the QOS provisions on the local segment, and the avoidance of the "all packets are treated equally" issue, which falls onto the hub or switch servicing segment. 802.1p QOS provides prioritization of packets traversing a subnet. Thus, when the local segment becomes congested and the hub or switch workload results in the delay (dropping) of packets, those packets with flags that correspond to higher priorities will receive perferential treatment, and will be serviced before packets with lower priorities. Disabled by default, select Enable from the Value drop-down menu to enable this parameter. Once enabled, select Disable from the Advanced tab Value drop-down menu to disable this parameter.

NOTE – Enabling 802.1p QOS also requires an 802.1p aware switch.

Checksum Offload Parameter

Normally the Checksum Offload function is computed by the protocol stack. By selecting one of the Checksum Offload parameters, the checksum can be computed by the Gigabit Ethernet Adapter. To enable one of the Checksum Offload parameters, select the parameter from the Advanced tab Value drop-down menu. These parameters described and shown below:

Rx TCP/IP Checksum - Enables receive TCP, IP, and UDP checksum offloading
Tx TCP/IP Checksum (default) - Enables transmit TCP, IP, and UDP checksum offloading
Tx/Rx TCP/IP Checksum - Enables transmit and receive TCP, IP, and UDP checksum offloading
None - Disables checksum offloading

Ethernet@WireSpeed™ Parameter

The Ethernet@WireSpeed parameter enables a 1000BASE-T Ethernet adapter to establish a link at a lower speed when only 2 pairs of wires are available in the cable plant. By default, the adapter is set to Enable. To disable the Ethernet@WireSpeed™ parameter, select Disable from the Value drop-down menu as shown below:

Disable - Disables Ethernet@WireSpeed
Enable (default) - Enables Ethernet@WireSpeed

Flow Control Parameter

The Flow Control parameter allows the user to enable or disable the receipt or transmission of PAUSE frames. PAUSE frames enable the adapter and the switch to control the transmit rate. The side that is receiving the PAUSE frame will momentarily stop transmitting. The recommended selection is Auto, which will optimize PAUSE frame receipt and transmission. Set to Auto by default, to disable Flow Control to receive, transmit, or receive and transmit PAUSE frames, select the appropriate parameter from the Advanced tab Value drop-down menu described and shown below.

Auto - (default) PAUSE frame receipt and transmission is optimized
Disable - PAUSE frame receipt and transmission is disabled (recommended)
Rx PAUSE - PAUSE frame receipt is enabled
Rx/Tx PAUSE - PAUSE frame receipt and transmission is enabled
Tx PAUSE - PAUSE frame transmission is enabled

Jumbo Mtu Parameter

The Jumbo Mtu parameter allows the adapter to transmit and receive oversized Ethernet frames that are greater than 1514 but less than 9000 bytes in length. Note that this parameter will require a switch that is able to process large frames.

Set at 1500 bytes by default, to increase the size of the received frames, increment the byte quantity in 500-byte increments from the Advanced tab Value counter, shown below.

Locally Administered Address Parameter

The Locally Administered Address is a user-defined address that will be used in place of the MAC address originally assigned to the adapter. Every adapter in the network must have its own unique MAC address. This locally administered address consists of a 12-digit hexadecimal number

Value - Assign a unique node address for the adapter.
Not Present - (Default) Uses the factory-assigned node address on the adapter.

The appropriate assigned ranges and exceptions for the Locally Administered Address include the following:

The range is 0000 0000 0001 to FFFF FFFF FFFD.
Do not use a multicast address (least significant bit of the high byte = 1).
Do not use all 0's or all F's.

Speed & Duplex Parameter

The Speed & Duplex parameter allows the user to set the connection speed and duplex mode of the network. Note that Duplex Mode allows the adapter to transmit and receive network data simultaneously. The adapter is set to Auto (optimum connection) by default. Set the speed and mode as described and shown below:

10 Mb Full - Sets the speed at 10Mbps and mode to Full Duplex
10 Mb Half - Sets the speed at 10Mbps and mode to Half Duplex
100 Mb Full - Sets the speed at 100Mbps and mode to Full Duplex
100 Mb Half - Sets the speed at 100Mbps and mode to Half Duplex
Auto - (Default) Sets the speed and mode for optimum network connection (recommended)

NOTE – 1Gbps speed is enabled by selecting Auto.

NOTE – N-way auto-negotiation requires that the link partner be set to the same Speed and Duplex setting for proper operation.

NOTE – Auto is the recommended selection. This selection allows the adapter to dynamically detect the line speed and duplex mode of the network. Whenever the network capability changes, the adapter will automatically detect and adjust to the new line speed and duplex mode. You must ensure that the link partner is also set to Auto. Note that 1000 Mbps makes use of Auto-Negotiation, some switches (Cisco 6509) do not allow setting Auto on ports but allow 1000 Mbps.

Wake Up Capabilities Parameter

The Wake Up Capabilities parameter allows the user to set the adapter to wake up from a low power mode when it receives a network wake up frame. Two wake up frames are possible: Magic Packet and Wake Up Frame. By default, the adapter is set to Both. To choose the type of frame the adapter will wake up from, select the appropriate Advanced tab parameter from the Value drop-down menu as described and shown below:

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

WOL Speed Parameter

The WOL Speed parameter allows the user to select the speed at which the adapter connects to the network during Wake-on-LAN mode. By default, the adapter is set to Auto. Set the speed as described and shown below:

NOTE – WOL Speed at 100 Mbps is supported only on the 5701, 5703, and 5704. 5700-based network adapters support only a WOL connection speed of 10 Mbps. This is the network speed when the system is in a standby mode awaiting wake up on LAN.

10 Mb - Sets the speed at 10 Mb
100 Mb - Sets the speed at 100 Mb
Auto (default) - Sets the speed for optimum network connection

NOTE – Wake on LAN is supported at 10 Mbps on the 5700 and 5704 adapters. The 5701 and 5703 adapters support Wake on LAN at 10 or 100 Mbps. Dell supports Wake on LAN on one device in the system at a time.

Save Settings

When the adapter parameter configuration is complete, click OK at the Gigabit Ethernet Controller Properties screen to accept the settings.
If prompted to restart your computer, click Yes. Note that, while it is not necessary to reboot the system for new adapter properties to take effect, rebooting is recommended to reinitialize all registers.
Verify that the adapter port LEDs operate as described in the Physical Description section of the Introduction.

Power Management

Power management specifies whether the operating system turns off the selected device if that device is able to be turned off. If the device is busy doing something, however, (servicing a call, for example), the operating system will not shut down the device. The operating system will try to shut down every possible device only when it is hibernating. Some devices must stay on at all times. If you need the device to stay on at all times, do not check this box.

NOTE – To enable the Wake-on LAN in standby mode for the Broadcom NetXtreme™ Gigabit Ethernet adapter you must select the "Allow the device to bring the computer out of standby" checkbox.

NOTE – WOL must also be enable on the device using the Advanced tab properties for ACPI WOL. Also, WOL must be enabled in the firmware in order to wake from a Windows shutdown or Out of Box WOL (see the DOS Diagnostic User's Guide).

Removing the Driver Software

Before physically removing an adapter from your system, first remove the adapter driver software.

Start your Windows 2000 system and log in. You must have Administrator privileges to remove the driver software.
Open the Control Panel and double-click the System icon.
At the System Properties screen, click the Hardware tab.
Click Device Manager to display the Computer Management window.

Expand Network adapters (click the + sign). All network adapters will display.
Right-click on the adapter to be removed and select Uninstall. A confirm Device Removal window displays.
