Windows NT 4.0 First-Time Installation
--------------------------------------

There are two ways to install the NIC:
1.  Using the EtherCD.
2.  Using the Installation Diskettes (created from the EtherCD).


Using the EtherCD
-----------------
To install the EtherLink NIC in a PC running Windows NT 4.0 using the
EtherCD:

1.  Install the NIC in the PC, as described in the user guide.

2.  Start Windows NT and log in.

3.  Insert the EtherCD into the CD-ROM drive. 
    The 3Com EtherCD Welcome screen appears.  

4.  Click NIC Software.

5.  Click NIC Drivers and Diagnostics.  

6.  Click Install NIC Driver.

7.  Click Install with Diagnostic program to install both the driver and the
    NIC diagnostic program, or click Install without Diagnostic program 
    to install the driver only.
    As soon as you click on the selection, the installation process
    starts.

8.  A message appears stating, "Do you have to install NIC drivers for
    any EtherLink PCI NICs?"  Click Yes.  
    The installer completes and causes the NIC driver to rebind to the
    protocols.  This may cause the Microsoft TCP/IP Properties screen
    to appear.  Complete the TCP/IP Properties page as appropriate for
    your network and click OK.

9.  When the installation is complete, an update dialog box appears.  
    Click OK. 

    The installation is complete.

Using the Installation Diskettes
--------------------------------
To install the EtherLink NIC in a PC running Windows NT 4.0 using the
installation diskettes:
 
1.  Install the NIC in the PC, as described in the user guide.

2.  Start Windows NT.

3.  Double-click the My Computer icon, then the Control Panel icon,

           Click Yes. See the Windows NT documentation for instructions. 
           
           If you have previously installed a Windows NT service pack, 
           you need to reinstall the service pack after the network 
           installation is complete to ensure that the Windows NT network 
           components are updated to the level of the service pack.

    The hour glass appears for a few seconds, and then the Adapters tab 
    of the Network screen reappears. The name of the installed NIC appears 
    in the list of network adapters.

9. Click Close.
    
    If the Microsoft TCP/IP Properties screen appears, enter the
    requested information for your network environment. Refer to 
    your system administrator or the Windows NT documentation for
    assistance.
   
    If the Microsoft TCP/IP Properties screen does not appear, the
