Driver installation for Microsoft Windows NT 4.0
------------------------------------------------

   1)  From Windows NT desktop, double click on "My Computer", 
       "Control Panel", and "Network" icons.

   2)  In the "Network" window, click the "Adapters" tab, and the "Add"
       button.  In the "Select Network Adapter" window, click the "Have 
       Disk" button.

   3)  Insert the Accton EN2230 Driver Disk in the diskette drive.

   4)  In the "Insert Disk" dialog box, enter the diskette drive path 
       name, i.e. A:\winnt40 (or B:\winnt40), and then click OK.

   5)  In the "Select OEM Option" box, select "Accton EN2230 Fast
       Ethernet CardBus PC Card", and then click the OK button.

   6)  When the "Accton EN2230 CardBus PC Card Setup" window shows up,
       you have to set up the EN2230 configuration parameters as
       described in the next section.  When you are done, click the 
       OK button.

   7)  In the "Network" window, click the Close button.  Windows NT then
       goes through a binding process.  When this process is complete, 
       Windows NT prompts you to restart the computer.  Click on the 
       Yes button.

   8)  Insert the Accton EN2230 card in one of the CardBus sockets.
       Attach the coupler to the back of the card, and connect a cable from the 
       RJ-45 connector at the back of the coupler to a hub or switch.
       Note if you are attaching to a 100 Mbps network, the cable has to be
       CAT-5 grade.

       You can now shutdown and restart the computer.  Please note that during
       Windows NT initialization, EN2230 must be properly connected to a
       hub or switch; otherwise the card and driver would not come up correctly.



EN2230 NDIS 4.0 Driver Parameters for Windows NT
------------------------------------------------

   1)  Connection_Type:      
          Specify the attached medium type. Default is AutoSense.

   2)  I/O_Port:             
          Specify the  starting address of I/O port range.
          The default value is D000.

   3)  Memory_Base_Address:  
          Specify the starting address of the Shared Memory range. 
          The default value is D0000.

   4)  Interrupt_Number:     
          Specify the IRQ number.
          The default value is IRQ 11.

   5)  Socket_Number:        
          Specify the socket number in which an EN2230 is inserted.
          The default value is "Auto detect".

   6)  Interrupt_Style:      
          Specify the CardBus bridge interrupt routing strategy. 
          Default is "PCI-IRQ-Routed".

   7)  Interrupt_Routing:    
          Specify which interrupt pin is used while the CardBus
          bridge is using "PCI-IRQ-Routed". Default is "INT A".

   8)  Store_And_Forward:    
          Setting this parameter causes the NIC to disable
          the transmit data pipeline operation. Default is "ON".

  It is extremely important to assign correct values for the 
  "Interrupt_Number" (IRQ value) and "Interrupt_Style" parameters.  
  If the system uses the "PCI-IRQ-Routed" interrupt style, it is also 
  important to assign the correct PCI "Interrupt_Routing" value (i.e. 
  INT A or INT B.)

  If in doubt about the values to assign to these parameters, you are
  advised to execute the CBOPEN.EXE card enabling program in a native 
  MS-DOS system first.  CBOPEN.EXE displays the IRQ value used, as well 
  as the  system's interrupt style.  For the Windows NT driver, you should 
  assign the same values to the above parameters as those displayed by 
  CBOPEN.
