CONFIGURING THE SPEED/DUPLEX SETTING FOR THE NETXTREME II
M
ONOLITHIC DRIVER
Since the typical environment where the NetXtreme II monolithic driver is used does not provide the means to configure
advanced network adapter properties, the driver file (b06nd.inf) was modified to include a section that allows it to be
configured for a specific speed and/or duplex. This provides a more robust connection to the network as it allows the adapter
to match the settings of its link partner (e.g., a switch, router, etc.).
To manually configure the speed and duplex
1. Open the b06nd.inf file with a text editor like Microsoft Notepad or WordPad.
2. Perform a search on the file for "Registry parameters" to locate the section that will allow you to configure the adapter
speed/duplex.
3. Once located, notice the following information shown.
[params_utp]
hkr, , req_medium, 2, "0"
[params_fiber]
hkr, , req_medium, 2, "65283"
These make up two separate sections that can be configured: one for standard RJ-45 copper interfaces (params_utp) and
one for fiber devices (params_fiber).
4. As described in the file, replace the value above in quotation marks under the correct section, depending upon the
network adapter in your system. The available values are shown below.
Options for copper interfaces:
• Auto (1 Gbps is enabled when that speed is supported) = "0"
• 10 Mbps Half Duplex = "65794"
• 10 Mbps Full Duplex = "258"
• 100 Mbps Half Duplex = "66050"
• 100 Mbps Full Duplex = "514"
Options for fiber interfaces:
• Auto (1 Gbps is enabled when that speed is supported) = "0"
• 1 Gbps Full Duplex = "771"
• Auto with 1 Gbps Fallback = "33539"
• Hardware default = "65283"
An example is provided in the file showing how to configure a copper interface for a 10 Mbps Full Duplex connection. The
example is shown below.
