   Duplex support
                                                            v1.00


Duplex support for the Intel EtherExpress(TM) PRO/100B adapter
==============================================================

Duplexing is a performance option that lets you choose how the
adapter sends and receives packets over the network.

There are three duplex modes:

*  Auto-negotiate. The adapter negotiates with the hub how to
   send and receive packets, either full or half duplex.

*  Full duplex (requires full-duplex hub). The adapter sends and
   receives packets at the same time, increasing adapter
   performance.

*  Half duplex. The adapter performs one operation at a time; it
   either sends or receives.


Configuring for full-duplex
===========================

If you have an auto-negotiating hub (an NWay* hub), the PRO/100B
adapter will automatically match the duplex setting at the hub.
If you don't have an auto-negotiating hub, you'll need to
manually configure the adapter for full duplex support.

Configuration is specific to the driver you're loading for your
NOS. See the sections for your network operating system (NOS)
below.

Note  You must set the Speed when configuring for full-duplex
      support. Don't leave the Speed set to Auto-negotiate.


DOS/ODI clients
---------------

Edit the NET.CFG file. Add the SPEED and FORCEDUPLEX parameters
under the link driver section. For example
   
   Link Driver E100BODI
       SPEED 100 (or 10 for 10 Mbps operation)
       FORCEDUPLEX 2


Windows* NT*
------------

Use the PRO Adapter setup program:

1  Click the Network button in the Control Panel.

2  Click the Configure button. The PRO Adapter setup program
   runs.

3  Click the Change button. Set Speed to 100 (or 10).

4  Click the Advanced button. Set Duplex to Full.


Windows 95
----------

Set the Speed and Duplex mode in the Control Panel:

1  Click the Network icon in the Control Panel and select the
   Configuration tab.

2  Select the Intel EtherExpress PRO/100B adapter.

3  Click the Properties button and select the Advanced tab.

4  Set Speed to 100 Mbps (or 10 for 10 Mbps operation).

5  Set ForceDpx to Full-Duplex.


Other NDIS 2.x based clients
----------------------------

Edit the PROTOCOL.INI file. Add the FORCEDUPLEX and SPEED
parameters to the E100B section. For example
   
   [E100B_NIF]          ; varies depending on your NOS
   SPEED = 100          ; or 10 for 10 Mbps operation
   FORCEDUPLEX = 2
