   4 Windows 95



Windows* 95 Installation Notes
==============================

LOCATION OF DRIVER:       \NT\E100B.SY_ (compressed)
LOCATION OF SETUP FILE:   \NET82557.INF


General Instructions
====================

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.  Select the
   option "Driver from disk provided by Hardware Manufacturer".
   
   NOTE: If the New Hardware Found dialog box doesn't appear, you'll
         need to manually configure the adapter. See the section on
         alternative ways to add a network adapter to Windows 95.

3  Insert the Configuration and Drivers disk in drive A and click OK.

4  A dialog box prompts for a location with "A:\". Click OK or change
   the location to the Configuration and Drivers disk.

5  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). If Windows
            95 requests the E100B.DOS file, it can be found on the 
            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.
   
   NOTE: Windows 95 will reference this adapter's driver as "Intel
         82557-based PCI Ethernet" not "Intel PRO/100+ adapter".


Installing the PROSet adapter diagnostic and configuration software
-------------------------------------------------------------------

The PROSet utility allows you to test the adapter in the Windows 95
environment.  It can also resolve some Windows 95 issues that may result
from changing or updating adapter hardware.

1  From the Explorer, double click on the 3.5 floppy disk icon. The
   Explore function can be accessed by clicking on the Windows 95 Start
   button with the right mouse button.

2  Locate the PROSet icon in the root directory of the diskette and
   click the right mouse button.  From the menu that appears, click
   Install.

3  When the PROSet utility has been copied to your computer, go to the
   control panel and click on the PROSet icon.  PROSet examines your
   computer and displays the PROSet window.  This window shows the
   adapter's I/O address, interrupt and Ethernet address.
   
   Note: The adapter's interrupt is set by the computer's BIOS.  If you
         have to change the interrupt, some computers allow you to
         change this setting, and some don't. Check your computer's
         documentation for details. PROSet will inform you of any
         problems with the current setting.

4  Click Test to begin diagnostics.


Advanced configuration parameters
---------------------------------

The defaults work correctly for most configurations. Please use caution
when changing these parameters.  To make a change, follow the steps
listed below.

Note: Be sure to use PROSet to configure these settings rather than the
      Advanced Configuration tab under Properties. Since this driver
      also supports all 82557-based adapters, some parameters have
      different values depending on which adapter is installed.  PROSet
      will display the proper values for the adapter you are 
      configuring. The Properties screen may not.

1  Double-click on the PROSet icon located in the Control Panel.

2  Click on the Settings button.

3  If you need to make changes to Speed and/or you are using a full
   duplex hub, change these options on the Basic Settings menu.

4  Click on Advanced.

5  For the highlighted Property on the left, the Value is displayed on
   the right.

Duplex Mode - Default Setting: Auto Duplex Detect
   
   A performance option that lets you choose how the adapter sends and
   receives packets over the network. A regular adapter can perform only
   one operation at a time (half-duplexing). The PRO/100+ adapter has
   the ability to send and receive packets at the same time (full-
   duplexing). In order to reap the benefits of full duplexing, you MUST
   have a full duplex hub or switch.

   Note: The PRO/100+ adapter supports auto-negotiate, full and half 
         duplex at 10 or 100 Mbps.

   
   Auto Duplex: The adapter negotiates with the hub how to send/receive
      packets, either full or half duplex.  You must use a switch or hub 
      that supports Auto-negotiation (also known as Nway).
   
   Full Duplex: The adapter sends and receives packets at the same time.
      This improves the performance of your adapter. Set duplex mode to
      full duplex ONLY if you have a full duplex switch or hub.
   
   Half Duplex: The adapter performs one operation at a time. It either
      sends or receives.

Note: If you select Full duplex you must manually set the Speed
      parameter to 100. Do not leave speed set to auto-detect.

The PRO/100 adapter has the added ability to "talk" to the switch or hub 
and determine at which mode to communicate (either full or half duplex). 
This is called auto-negotiation. You must have an auto-negotiating
switch or hub (an Nway* hub) to get full duplex support with the Duplex
mode set to Auto Duplex Detect. If you don't have an auto-negotiating
hub, set Duplex mode to Full Duplex and if you are operating at 100Mbs,
you must set the Speed parameter to 100.  Auto-speed detect will not
work at 100mb.

Coalesce Buffers - Recommended setting:  8
   
   Number of memory buffers available to the driver in case the driver
   runs out of available Map Registers. This packet area is also used
   when a packet consists of many fragments.

Map Registers - Recommended Setting: 64
   
   Map registers are system resources used in physical to virtual
   address conversion with bus mastering cards. The Map Registers
   parameter specifies how many registers should be allocated to the
   driver.

Receive Buffers - Recommended setting:  16
   
   Specifies the number of buffers used by the driver when copying data
   to the protocol memory.

Transmit Control Blocks - Recommended setting:  16
   
   Specifies how many transmit control buffers the driver allocates for
   adapter use.  This directly corresponds to how many outstanding
   packets the driver can have in its "send" queue.

Speed - Default setting:  Auto Detect
   
   This parameter lets the PRO/100+ adapter know what speed
   to use on the Ethernet wire.  The choices are 10 Mbps, 100 Mbps, and
   Auto Detect.  In Auto Detect mode, the adapter detects if its
   environment can support 100 Mbps speed. It then sets the speed to 100
   if it can, or 10 if it can't. If you are using a crossover cable
   connected to another adapter, set the speed to either 10 Mbps or 100
   Mbps.


Manually Adding an Adapter in Win 95
====================================

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 PCI Ethernet Controller.
5. Click the Driver tab, then click Change Driver.
6. Select Network Adapters and click OK. 
7. Click Have Disk. Insert the PRO/100+ Server adapter disk
   and click OK.
8. Follow any prompts for Windows 95 installation disks and restart
   when prompted. 

   IMPORTANT: You must reboot after installing each adapter port.

To install PROSet software (recommended), continue to the section
"Install PROSet Software" in the Install Guide.


Alternatives for Adding Network Cards to Windows 95
===================================================

Windows 95 automatically detects Plug and Play devices when they are
added to the system, and either loads drivers for the new device, or
prompts the user for the location of the drivers.  However, this feature
does not work the same on all computers and with all cards.

This text provides alternatives for adding drivers for newly installed
hardware. One of these should work in cases where the general
instructions above don't work.

Some of these methods arrive at the same dialog boxes, but yield
different results because of the path taken.


Control Panel ... SYSTEM (recommended method)
---------------------------------------------
    
    1   Double-click My Computer.
    2   Double-click Control Panel.
    3   Double-click System.
    4   Click the Device Manager tab.
    5   Double-click Other Devices (question mark icon).
    6   Double-click PCI Ethernet Controller.
    7   Click the Driver tab.
    8   Click Change Driver.
    9   Select Network Adapters and click OK.
    10  Click Have Disk, insert the Configuration and Drivers disk
        in the appropriate drive, and click OK.
   
   If you get into Device Manager and do not have an Other Devices icons
   in the device list, Windows 95 did not detect your card at all.  This
   condition indicates a problem with the adapter itself, or with the
   system BIOS, rather than a Windows 95 Plug and Play problem.


Control Panel ... Add New Hardware
----------------------------------
    
    1   Double-click My Computer.
    2   Double-click Control Panel.
    3   Double-click Add New Hardware.
    4   Click Next.
    5   Select the No option and click Next.
    6   Select Network Adapters and click Next.
    7   Click Have Disk, insert the Configuration and Drivers disk
        in the appropriate drive, and click OK.
    8   Select "Intel EtherExpress PRO/100+ Server Adapter" and click
        OK.
    9   Click Next and click Finish.



Hints and tips
--------------

1. Multiple Adapters in Windows 95:
   
   If you have multiple Intel adapters installed in the system, be
   sure to install and run PROSet. It will automatically detect that you
   have multiple adapters and update the EID (Ethernet ID) field, which
   is required by Windows 95 for card identification.
   
   Background: If multiple network adapters are installed in a Windows
   95 system, each card must be identified by the last 8 digits of the
   Ethernet address.  However, Windows 95 requires decimal numbers which
   makes it necessary to perform a hex to decimal conversion.  For
   example, an adapter with the Ethernet address of 00AA00123456 would
   require putting 1193046 as the Ethernet ID value (00123456 converted
   to decimal is 1193046). Windows calculator, in scientific mode, is a
   tool you can use for the conversion if you need to do the conversion
   manually.

2. Windows 95 Push Installation:
   
   You can find some support files and readme information in \WIN95\PUSH
   to help with Windows 95 push installations using the PRO/100+
   adapter.

3. 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

4. Moving adapters to different slots:
   
   When removing a PCI adapter and placing it in a different slot,
   Windows 95 retains the old instance of the driver and adds a new one
   for the new slot/card combination. This behavior is common to any
   adapter. The driver stops functioning when the number of accumulated
   old drivers reaches 2 (for a total of 3 installed drivers, including
   the current driver). The workaround is to remove the old driver
   before changing slots, or to run PROSet and allow it to associate the
   card with the appropriate instance of the driver.

5. Swapping 82557 or 82558-based adapters in the same slot.

   In order for Windows 95 to properly recognize a different 82557 or
   82558-based adapter in the same slot, the EID must be updated. This 
   update can be achieved in a few different ways. Perform one of the 
   following items for the update to happen.
   
   -  The easiest method is to run PROSet after swapping the adapters.
   
   -  Or, remove the adapter by performing a Remove Device in the Device
      Manager or Remove Adapter in Network Control Panel. Then, shut
      down the computer and install the other 82557 or 82558-based
      adapter.
   
   -  Or, shut down the computer, remove the adapter, turn on the
      computer and start Windows 95 without any adapter. At this point,
      Windows 95 detects that the adapter was removed and deletes the
      obsolete registry entries.  Shut down the computer, install the
      adapter, start Windows 95, and perform a regular adapter
      installation.
