Configuring the Speed and Duplex Settings 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 duplex mode. This
provides a more robust connection to the network as it allows the adapter
to match the settings of its link partner (for example, a switch or a router).
To manually configure the speed and duplex, do the following:
1. Open the b06nd.inf file with a text editor like Microsoft Notepad or
WordPad.
2. Search the file for Registry parameters to locate the section that allows
you to configure the adapter speed and duplex mode.
Once located, notice the following information:
[params_utp]
hkr, , req_medium, 2, "0"
[params_fiber]
hkr, , req_medium, 2, "65283"
These are two separate sections that can be configured: one for
standard RJ-45 copper interfaces (params_utp) and one for fiber
devices (params_fiber).
3. 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"
