General Instructions
--------------------

After putting the adapter in the computer, you need to configure it
under Windows NT.

1. Double-click the Network icon in the Control Panel.

2. Click the Add Adapter button.

3. Do NOT select an adapter from the list. Instead, scroll to the
   end of the list and select:
      
      <Other> Requires disk from manufacturer.

4. Click the Continue button.

5. Insert the CardAssistant Disk into your floppy drive
   and click OK.

6. Select AT-2560 Adapter and click OK.

7. The A2560SET program automatically scans computer resources
   and determines the settings assigned to your adapter.  It also adds 
   an icon to the Control Panel for future use of A2560SET.

8. Click the Test button in the A2560SET program to run diagnostics.

   If you've just added the adapter, the network driver won't be active
   and the diagnostics will test the adapter and its connection to the
   network. If you're testing an adapter that's already been installed,
   the network driver will probably be active and the diagnostics will
   test the driver. This diagnostic tracks the driver's actual network
   activity.

9. Click OK to exit the test screen and return to the A2560SET main
   menu.

10. Click OK to accept the adapter's configuration and exit the A2560SET
    Program.

11. Click OK in the Network Settings dialog. Other configuration screens
    may appear. Configure as desired. When prompted, restart Windows NT.

12. Repeat the General Instruction process for installing additional
    adapters.


                                    
                            ADAPTER SETTINGS

There are two ways to run A2560SET, which allows changing the adapter
settings.
   
   -  From the Control Panel double click on the A2560SET icon.
   
   -  From the Network Settings screen highlight the 
      adapter and click Configure.

1. From the main A2560SET menu click the Change button to get to the
   Adapter Settings screen. The defaults work correctly for most
   configurations.


   NETWORK SPEED
   -------------
   
   Setting:  100

      This parameter lets the adapter know what speed to use on the 
      Ethernet cable. 


   DUPLEX MODE 
   -----------
   
   Half duplex (default):  The adapter performs one operation at a time. 
   It either sends or receives.

   A regular adapter can perform only one operation at a time (half-
   duplexing). 


   Full duplex:  The adapter sends and receives packets at the 
   same time.  Set duplex mode to full duplex only if you have 
   a full duplex switch.


2. Click the Advanced button in the Adapter Settings screen to change 
   the Advanced setting.
      
      Note: The defaults work correctly for most configurations. Please
      use caution when changing these parameters. Use the on-line
      help for additional information.


   COALESCE BUFFERS
   ----------------
   
   Recommended setting:  8


   RECEIVE BUFFERS
   ---------------
   
   Recommended setting:  16


   TRANSMIT CONTROL BLOCKS
   -----------------------
   
   Recommended setting:  16


   MAP REGISTERS
   -------------
   
   Recommended settings:
      PCI:    MapRegisters = 8 (default for NT 3.5)
      PCI:    MapRegisters = 64 (default for NT 3.51 or later)
