   Windows 95 Installation and Peer-to-Peer Networking Information

-----------------------------------------------------------------------

This file describes how to install an EtherLink NIC in a PC
running Windows 95. It also describes how to:

   Update EtherDisk software.

   Remove the NIC driver and EtherDisk software.

   Troubleshoot installation problems.

   Use Windows 95 peer-to-peer networking.  

   NOTE: For instructions on upgrading a PC from Windows 95 
   to Windows 98 that already has an EtherLink NIC installed, 
   see the WIN98.TXT file on EtherDisk diskette 3.


First-Time Installation
------------------------

The NDIS 3/4 drivers for Windows 95 are the 32-bit driver version that 
Windows 95 uses as the default driver.  The NDIS 2.0 driver is the real-
mode 16-bit driver.  The actual driver files that 3Com supplies are:
 
  EL90XND3.SYS (NDIS 3 driver)
  EL90XND4.SYS and EL90XBC4.SYS (NDIS 4 driver)
  EL90X.DOS (NDIS 2 driver)

Some versions of Windows 95 do not have a built-in driver for the 
EtherLink NICs. In any case, it's best to install the latest driver
using the EtherDisk diskettes that came with the NIC.

The 3Com EtherDisk diskettes 1 and 2 and the Windows 95 installation 
files are needed during the installation.

To install the NIC in a PC running Windows 95:

1.  Install the NIC in the PC, as described in the user guide, 
    
2.  Turn on the power to the PC. 
    Windows 95 detects the NIC.  Depending on the version of Windows 95
    that you have installed, the New Hardware Found dialog box appears
    or the Update Device Driver Wizard starts.

    NOTE: If Windows 95 detects the NIC but starts copying files right
          away without prompting you for a diskette, you have an existing 
          version of the driver already installed on your PC.  To update 
          the driver, reboot the PC, and then follow the instructions in the 
          "Updating EtherDisk Software" section below.  
          
          If Windows 95 does not detect the NIC at startup, the PC may 
          have installed a "Generic PCI Ethernet" driver (see the 
          "Troubleshooting" section below), or Plug and Play mode may
          have been disabled.  In this case:

          a.  Double-click the Add New Hardware icon in the Windows 
              Control Panel.
          b.  Continue to click Next until Windows 95 asks if you want 
              it to search for new hardware.  
          c.  Click No, and then click Next.  
          d.  Choose Network Adapters in the Hardware Types menu, and
              then click Next.  
          e.  Click Have Disk, and insert EtherDisk diskette 1.  Go to
              Step 3 when prompted for EtherDisk diskette 2.

Troubleshooting Tips
--------------------
1.  If an error message appears during the installation, stating that 
    the .INF file cannot be found in the specified location, verify 
    that Windows 95 is looking at the correct location. The file 
    should be in the root directory of the 3Com EtherDisk diskette 1.  
    The filename is W95EL90X.INF.

    If the W95El90X.INF file is missing, download the file from one of
    3Com's download sites (such as the World Wide Web or FTP site), and 
    make sure that you expand it properly. See the SUPPORT.TXT file on this 
    diskette for more information.

2.  If Windows 95 does not detect new hardware after you install the NIC
    and power on the PC, the system may have installed a "Generic PCI Ethernet"
    driver.  In this case:

    a. Double-click on the System icon in the Windows Control Panel.
    b. Select the Device Manager tab.
    c. Under Network adapters, the 3Com EtherLink driver appears with a 
       yellow exclamation in front of it.
    d. Under Other Devices, a PCI Ethernet Controller appears with a 
       question mark in front of it.
    e. Highlight the PCI Ethernet Controller under Other Devices,
       and then click Remove.
    f. Select Yes if prompted to confirm the removal of the device.  
    g. Select No if prompted to restart the PC.
    h. Highlight the 3Com EtherLink NIC under Network adapters,
       and then click Remove.
    i. Select Yes if prompted to confirm removal of this device.  
    j. Select No prompted to restart the PC.
    k. Click OK to save all changes.  
    l. Restart the computer.

3.  To verify that the actual NDIS driver was copied to your Windows 95
    system, compare the date of the driver .SYS file in the 
    directory of your hard drive with the date of the one in the root
    directory of the 3Com EtherDisk diskette 2. The dates should be the
    same.


General Overview of Peer-to-Peer Networking
-------------------------------------------
In a peer-to-peer network, a relationship exists between two or more "like"
computers.  Each computer may make portions of its devices (such as disk
drives, CD-ROM drive, and printers) available to other computers on the
network.  You can decide what to make available to other users.  When you
share a disk drive or folder, you also need to decide if you want to grant
other users the right to store and change information on your drive or
folder.

The general characteristics of a peer-to-peer network are:

The network provides the capability to share resources with any computer on
the network.  When you share resources, your computer acts as a server for
all other computers in the network while still retaining all its capability
for your use.  In a server-based network, only the resources on the
dedicated server can be shared.

A peer-to-peer network is more difficult to administer than a server-based
network. Its flexible resource-sharing and lack of central management and
control make management difficult. However, the network works with your 
existing equipment and does not require the purchase of a dedicated server.  
This lowers the cost of networking.


Peer-to-Peer Networking with Windows 95
----------------------------------------

Microsoft Windows 95 comes with a built-in peer-to-peer network.  It
also supports a wide range of network environments and network software
vendors to work with dedicated networks.

To configure Windows 95 for peer-to-peer networking:

1.  Install Windows 95 and the EtherLink NIC.

2.  Configure your network configuration as outlined in the previous 
    instructions in this document.  

3.  Make sure that you have the Microsoft Network client in your 
    network configuration.

Before you can share resources on your computer, you need to add file and
print sharing capabilities to your network configuration.  

To add file and print sharing capabilities:

1.  Open the Windows Start menu, select Settings, and then select
    Control Panel. 

2.  Double-click the Network icon.

3.  In the Network window, click Add.

4.  Select Service in the list of Network Component Types, and then 
    click Add.

5.  Select Microsoft from the list of manufacturers in the left column.

6.  Select File and printer sharing for Microsoft Networks in the right
    column.

7.  Click OK.
    The Network window appears.

8.  Select the Identification tab.

9.  Assign a computer name.
    This computer name identifies your PC on the network. This name
    must be unique.

10. Assign a workgroup name.  
    The workgroup name must be the same for all of the computers on your 
    network with which you want to share information.  More than one 
    workgroup may exist on a network, but members of one workgroup cannot
    directly see members of another workgroup.

11. Assign a computer description.
    The description allows other users in your workgroup to know what is 
    available on your computer (such as a printer or scanner).  

12. Click OK.
    Windows 95 prompts you for the location of the Windows 95 CD-ROM or 
    diskettes containing the files needed for sharing.  
    
13. Assuming the CD-ROM is drive D: on your computer, type:

    D:

14. Click Yes when Windows 95 prompts you to shut down and reboot the 
    computer.  
   
    After Windows 95 reboots, you are ready to share resources.

15. To share a device (such as a disk drive)::
    a.  Double-click the My Computer icon.
    b.  Click the right mouse button over each device (for example, your
        C: drive) you want to share.  
    c.  From the menu that appears, select Sharing. 
    d.  Click Shared As in the Sharing window.
    e.  Assign a share name to the device, and then click OK.  
        The device is now shared.

16. To share a folder rather than an entire disk drive:
    a.  Select a drive and click the left mouse button to open the drive.
    b.  Select the folder and click the right mouse button.
    c.  Select Sharing from the menu.  
    d.  When the Share menu opens, select a shared name and the way you 
        want to share the folder.  
        Read Only--no user can write to or delete your shared files and 
        folders.  
        Read and write--gives other users permission to delete or change 
        files and folders.  

    For more information on peer-to-peer networking, see your Microsoft 
    Windows 95 manual.
