- WINDOWS NT* 4.0 INSTALLATION NOTES
  ==================================

LOCATION OF DRIVER:    \E100BNT.SYS (NDIS 4.0)
                       \OEMSETUP.INF
      
      Note: NT 4.0 ships with a driver for the PRO/100B adapter.  
            However, you must install the more recent driver from
            the Intel(R) adapter disk or CD.

      Note: It is recommended that you install the latest Service
            Pack for Windows NT 4.0, available through Microsoft.


General Instructions
--------------------

After putting the adapter in the computer, you need to configure it
under Windows NT.

1  Double-click the Network icon in the Control Panel.

2  Select the Adapter tab.

3  Click Add.  You'll see a list of adapters.

4  Don't select an adapter from this list.  Instead, insert the 
   Intel adapter disk or CD into the appropriate drive and click 
   Have Disk.

5  Enter the appropriate drive for your disk media (A:, D:, etc.)
   and click OK.  Then follow the prompts to complete installation.
   When the adapter is added you'll see a new adapter listed in the
   Network adapters list.

6  Click Close to finish and configure any protocols as prompted.

7  Restart Windows NT when prompted.

- WINDOWS 2000 INSTALLATION NOTES
  ===============================

LOCATION OF DRIVER:       \E100BNT5.SYS (NDIS 5.0)
LOCATION OF SETUP FILE:   \NET82557.INF


  NOTE: 
  -----
        Windows 2000 does not offload fragmented IP traffic to
        the adapter.

  NOTE for PRO/100 S Adapter Users: 
  ---------------------------------
        If Windows 2000 is enabled for IPSec encryption, the
        PRO/100 S adapter automatically offloads the intensive
        encryption and authentication functions onto the IPSec
        co-processor on the adapter. (The PRO/100 S adapter driver 
        registers with the operating system to automatically enable
        this function.)  The result is an increase in throughput
        and a decrease in CPU utilization.

  Note for Windows NT 4 Users:
  ----------------------------

        If you upgrade your operating system from Windows NT 4.0 to
        Windows 2000, you may need to re-specify your settings for
        Speed and Duplex in PROSet.


Install Network Drivers from Disk
---------------------------------

After you put the adapter in the computer, connect
the cable, plug in the power cord and start Windows, Windows
automatically installs a driver for the adapter from its own
library of drivers.

However, you should still install the driver that is included
on the Intel adapter CD to ensure you have the complete
set of features for the adapter.  You can install this driver
manually using the following instructions:
 
To update the driver for the adapter:

1.  Insert the Intel adapter CD or disk.
2.  From the Control Panel, double-click the System icon, select
    the Hardware tab, and click the Device Manager button.
3.  Select "Network Adapters" and right-click on the appropriate
    adapter listing to display its menu.  Then click
    the Properties menu option.
4.  From the Properties dialog box, click the Driver tab and
    click the Update Driver button.  The Update Device Driver
    Wizard appears.  Click Next.
5.  At the prompt "What do you want the wizard to do?", select
    the "Search for a suitable driver for my device" radio button,
    and click Next.
6.  Select the appropriate media checkbox and click Next.
7.  Select the "Install one of the other drivers" check box and
    click Next.
8.  Select the driver on the Intel adapter CD or disk and click
    Next.
9.  Restart your computer if prompted.

After restarting Windows, connect to your network by double-clicking
the My Network Places icon on the desktop.

LOCATION OF SETUP FILE:   \NET82557.INF


DETERMINING YOUR VERSION OF WINDOWS 95
======================================

    Follow the steps below to determine which version of Windows 95 you 
    are running:

    1.  Click on the Start button.
    2.  Select Settings.
    3.  Select the Control Panel.
    4.  Double-click on the System icon. The System Properties dialog 
        box opens.
    5.  Select the General tab. Information about your system is
        displayed, including the version of Windows 95 you are
        running, under System.

General Instructions (For version Windows 95B (OSR2x) Only)
===========================================================

1  Install the adapter in the computer and turn on the power.  Have the
   Windows 95 CD ROM available, as you will need it to copy additional
   files. While Windows 95 is starting, it will detect the new hardware.

2  When Windows 95 starts, a New Hardware Found dialog box appears. It
   identifies the adapter as a PCI Ethernet Controller.  Insert the
   Configuration and Drivers disk or CD in the appropriate drive,
   and at the Update Device Driver Wizard, click Next.

   NOTE: If the New Hardware Found dialog box doesn't appear, you'll
         need to manually configure the adapter. See the section
         "Alternatives for Adding Network Cards to Windows 95".

3  The Update Device Driver Wizard lists the driver it has found.
   Click Finish.

4  A dialog may appear requesting Windows 95 system network files. If
   so, follow the instructions.
      
      Note: The Windows 95 system files are typically available on the
            Windows 95 CD in the win95 directory (D:\win95) or, on a
            pre-installed system, they may be located in the \Windows\
            Options\Cabs directory. If Windows 95 requests the E100B.DOS
            file or the 8255XNDI.DL_ files, they can be found on the
            Intel Configuration and Drivers disk.

6  The Systems Setting Change dialog appears indicating you should
   restart the system for changes to become effective.  Remove the
   Configuration and Drivers disk from the drive and click Yes for the 
   changes to take effect.


Manually Adding an Adapter in Windows 95 (For version Windows 95B
(OSR2x) Only)
=================================================================

If the New Hardware Found dialog box does not appear at startup and
you cannot connect to the network, check the Device Manager list to
see if the new adapter is present. If it is not, follow these steps:

1.  From the Control Panel, double-click the System icon.
2.  Click the Device Manager tab.
3.  Double-click Other Devices (question mark icon) in the list area.
4.  Double-click a PCI Ethernet Controller.
5.  Click the Driver tab, then click Update Driver.
6.  Insert the Configuration and Drivers disk or CD in the appropriate
    drive, and at the Update Device Driver Wizard, select "No" and 
    click Next.
7   Click Have Disk, insert the Configuration and Drivers disk
    in the appropriate drive, and click OK.
8.  At the Select Device dialog box, click OK again.
9.  Follow any prompts for Windows 95 installation disks and restart
    when prompted.
      
      Note: The Windows 95 system files are typically available on the
            Windows 95 CD in the win95 directory (D:\win95).


Advanced Configuration Parameters
---------------------------------

An advanced configuration utility called PROSet was installed on your
system when you installed the adapter. To start PROSet,
double-click on the PROSet icon in the Windows control panel. For
additional information, click Help in the PROSet window.

The defaults specified for the adapter work correctly for most
configurations.  When making changes to any adapter settings,
be sure to use PROSet.  


Hints and Tips
--------------

   Using NDIS 2 driver and Full Duplex:
   
   Installing the NDIS 2 driver through Windows 95 does not properly set
   the driver to Full Duplex.  In order for you to use Full Duplex with
   E100B.DOS, you must edit the PROTOCOL.INI file in the Windows 95
   directory to include:
   
   [E100B_NIF]
   Drivername = E100B$
   FORCEDUPLEX = 2

 - CHANGING ADAPTER SETTINGS WITH PROSET
   =====================================

PROSet is an advanced configuration utility which allows you to
change adapter settings.  PROSet is automatically installed when
you install the adapter's Windows drivers.

To access PROSet, double-click on the PROSet icon in the Control
Panel.
   
From the main PROSet menu, click the Advanced tab to view and modify
adapter settings. The defaults work correctly for most configurations.


Link Speed & Duplex
-------------------

Recommended setting:  Auto Detect (default)

This parameter lets the adapter know what speed to use on the 
Ethernet wire, and how to send/receive packets, either full or half
duplex.

Options available include: 
      
      Auto Detect: The adapter detects whether its environment can
            support 100Mbps speed (and uses 100Mbps if possible), and
            negotiates with the switch on how to send/receive packets
            (either full or half duplex). 

            NOTE:  You must have an auto-negotiating switch to get full
                   duplex support with the Link Speed & Duplex option
                   set to Auto Detect.

      10Mbps/Half Duplex: The adapter uses 10Mbps speed and performs
            one operation at a time. It either sends or receives.
      
      10Mbps/Full Duplex: The adapter uses 10Mbps speed and sends and
            receives packets at the same time. This improves the
            performance of your adapter. Select this mode only if you
            have a full duplex switch.

      100Mbps/Half Duplex: The adapter uses 100Mbps speed and performs
            one operation at a time. It either sends or receives.
      
      100Mbps/Full Duplex: The adapter uses 100Mbps speed and sends and
            receives packets at the same time. This improves the
            performance of your adapter. Select this mode only if you
            have a full duplex switch.
