Windows 98 that already has an EtherLink 3C90x or 3C90xB/3C90xC NIC installed.

Follow the instructions for the type of NIC (3C90x or 3C90xB/3C90xC) that
you have installed in the PC.

NOTE:  If you have already upgraded to Windows 98 without following these
instructions and are experiencing problems with the NIC, see the
next section, "Performing a Fresh Installation of Windows 98 in a PC with
an EtherLink NIC Installed."


3C90x NIC family
----------------

   1.  Start Windows 95.

   2.  Open the Windows Start menu, select Settings, and then

       components that may be needed when the NIC is reinstalled later.   

   6.  Shut down the Windows, power off the PC, and then remove the NIC. 
 
   7.  Power on the PC, start Windows 95, and then install Windows 98.

   8.  After Windows 98 is installed, go to step 1 of "First Time 
       Installation" above to install the NIC.


3C90xB or 3C90xC NIC family
---------------------------

   If you have an EtherLink 3C90xB or 3C90xC NIC installed, 
   no special installation or configuration is necessary. 
   The upgrade from Windows 95 to Windows 98 should not affect 
   your NIC's installation or performance. 

   However, if you upgraded from Windows 95 (OSR2) to Windows 98, 
   the NIC continues to use the NDIS 4 driver instead of the 
   NDIS 5 driver.

   To update to the NDIS 5 driver:
      1.  Start Windows 98.
   
      2.  Right click on the Network Neighborhood icon.

      3.  Click Properties.

      4.  Double-click the EtherLink NIC listing.

      5.  Select the Advanced tab.

      6.  Click on the NDIS driver version.

      7.  Under Value, select NDIS 5.

      8.  CLick OK to close the Properties window.

      9.  Click OK to close the Network window.
          The NDIS driver is updated to NDIS 5.


Performing a Fresh Installation of Windows 98 in a PC with an
EtherLink NIC Installed
-----------------------------------------------------------

Review the section for the type of EtherLink NIC (3C90x or 
3C90xB/3C90xC) that you have installed in the PC.
     
3C90x NIC family
----------------

     If you performed a fresh installation of Windows 98 in a PC
     that already has an EtherLink 3C90x NIC installed, or if you 
     installed a 3C90x NIC in Windows 95 and then upgraded to 
     Windows 98 without following the instructions in "Upgrading From 
     Windows 95 to Windows 98," the installation is damaged.  This is
     because Windows 98 installs its own built-in driver to support 
     the 3C90X NIC.  This driver is old and may not work properly 
     on some PCs.  When you reboot the PC, both the EtherDisk and 
     Windows 98 drivers load and attempt to bind to the same NIC.
  
     The symptoms of this problem vary.  You may get a general 
     protection fault in module NDIS.VXD.  If this happens,
     you must reboot Windows in Safe Mode to recover. You will not 
     be able to connect to the network.  If you run the 3Com NIC 
     Diagnostic program for Windows, you will get errors when you 
     execute the NIC diagnostic tests.

     To correct this problem, update the NIC driver and EtherDisk 
     software.  Follow the instructions in "Updating NIC Software" 
     later in this document.
