Intel PCI Express Gigabit Ethernet Connections for Microsoft Windows CE 6.x
===========================================================================

May 28, 2009



Summary
=======

The configuration files provided with the Windows* CE driver enable support 
-Intel(R) 82574L Gigabit Ethernet Controller

This technical note provides information on installation and configuration.



Package Contents
================

e1q51ce6.dll - Windows CE 6.0 driver for Intel Gigabit Ethernet Controller
e1q51ce6.reg - Registry merge file for e1q51ce6.dll driver
e1q51ce6.txt - This support file


Single Network Interface Configuration
======================================

Use an ASCII text editor to read and modify the contents of the E1Q51CE6.REG 
file, and merge the content into the platform registry definition file 
PLATFORM.REG. The protocol information should be modified (e.g., different IP
address or gateway) to correspond to your application.

Bindings, routes, and linkages are now handled by the operating system as 
well, eliminating the need to set the linkage and route by hand.  


Multiple Network Interface Configuration
========================================

The only things that may need to be modified are the subnet mask, default 
gateway, and IP address, in the case of static IP usage.


Speed and Duplex setting
=======================

In the default mode, an Intel® PRO/100 adapter or Intel® Gigabit Network Adapter 
using copper connections will attempt to auto-negotiate with its link partner to 
determine the best setting. If the adapter cannot establish link with the link 
partner using auto-negotiation, you may need to manually configure the adapter 
and link partner to identical settings to establish link and pass packets. 
This should only be needed when attempting to link with an older switch that 
does not support auto-negotiation or one that has been forced to a specific 
speed or duplex mode.

The settings available when auto-negotiation is disabled are:

10 Mbps or 100 Mbps Full duplex (requires a full duplex capable link partner 
set to full duplex). The adapter can send and receive packets at the same time. 
You must set this mode manually (see below).

10 Mbps or 100 Mbps Half duplex (requires a link partner set to half duplex). 
The adapter performs one operation at a time; it either sends or receives. 
You must set this mode manually (see below).

"Forcing to 1 Gigabit is not allowed as per the Gigabit specification"


Configuring Speed and Duplex
============================

Speed and Duplex setting can be changed (forced) by assigning appropriate 
data values to Registry key parameter "*SpeedDuplex". (see e1q51ce6.reg file)
The allowable values are
    "*SpeedDuplex"=dword:1   	; 10  Mbps Half duplex
    "*SpeedDuplex"=dword:2	; 10  Mbps Full duplex
    "*SpeedDuplex"=dword:3	; 100 Mbps Half duplex
    "*SpeedDuplex"=dword:4	; 100 Mbps Full duplex


More information on Speed and Duplex
====================================

"*SpeedDuplex" parameter is per port. Depending upon the port (eg. port#1 or #2 
in dual port card), the "*SpeedDuplex" reg parameter must be set manually in 
e1q51ce6.reg file under port specific system-defined-reg key.


Duplicate Display Naming
========================

When the Display Name (""Intel(R) Gigabit Ethernet Controller") is used 
for more than one network interface, changes cannot be made once the Windows CE
image is loaded. This behavior is due to a limitation in the OS. Windows CE treats 
adapter settings with identical Display Names as the same. When a change is 
made in the Network Configuration (Control Panel) to one network interface, 
it affects all the others with the same Display Name. When a static IP 
address is used in the Windows CE build, all network interfaces with the same 
Display Name will list the same IP address. The Registry settings will have 
the correct values. This limitation does not apply in a PC development 
platform due to the ability to remove and re-insert a network adapter for the 
changes to take effect.
