            FOR USE WITH MICROSOFT OS/2 LAN MANAGER  
  
                       INSTALLATION GUIDE  
                              for  
                     DOS NDIS VERSION 01.00.00  
  
These drivers are designed to be used with 3Com 3+Open, the   
Microsoft OS/2 LAN Manager OEM distribution release 1.0 or later,
and other compatible OEM versions of LAN Manager.  The drivers 
named NDISPD conform to the Network Driver Interface 
Specification (NDIS) defined by Microsoft/3Com. This release 
supports only the DOS workstation under 3Com 3+Open.

OVERVIEW  
  
1) Install your Cabletron Network Adapter card.  
   Use diagnostics to verify correct installation (Optional).  
2) Install 3Com 3+Open LAN MANAGER at this time if not previously
   installed.  
3) Install Cabletron files from Release disk.  
4) Modify CONFIG.SYS to reference Cabletrons packet driver file  
   (CSIPD_E.EXE).  
5) Modify CONFIG.SYS to reference Cabletrons NDIS MAC driver     
   (NDISPD.DOS).  
6) Modify PROTOCOL.INI file to reflect use of Cabletrons adapter
   card.  
7) Modify PROTOCOL.INI file to reflect "BINDINGS".  
8) Reboot system and follow LAN MANAGER vendor instructions.   
  
Packet driver installation  
  
INSTALLING ON DOS WORKSTATIONS  
  
1) Install the Cabletron adapter card.  Proper installation can  
   be verified by running the diagnostic program under DOS.      
   Please refer to the DNI adapter card documentation and the   
   information in the DIAGS subdirectory.  
  
2) Install 3Com 3+Open LAN MANAGER or continue to next step if  
   previously installed.  The adapter selected does not matter 
   because the references to it will be replaced once the        
   installation is complete. The examples below assume the 
   3Com EtherLink II has been selected with 3+Open.   
   Do not start LAN Manager.
  
3) Copy the DOS NDISPD.DOS driver from the Cabletron DNI Drivers
   diskette to the driver directory used by LAN Manager.  For
   example, installing a 3+Open DOS workstation using the normal
   directory structure type:  
  
    COPY A:\LANMAN\NDISPD.DOS C:\3OPEN\DOSWKSTA\LANMAN\DRIVERS  
  
   Copy the packet driver software from the Cabletron DNI Drivers
   diskette to the driver directory used by the LAN Manager.  
   For example,installing a 3+Open DOS workstation using the     
   normal directory structure type:  
  
    COPY A:\CSIPD\CSIPD_E.EXE C:\3OPEN\DOSWKSTA\LANMAN\DRIVERS 
  
4) Modify the config.sys file to reference the Cabletron Packet  
   driver file. Use a text editor to add the following line      
   before the line which specifies the PROTMAN.DOS file.  
  
Add the line:  
  
    DEVICE=\3OPEN\DOSWKSTA\LANMAN\DRIVERS\CSIPD_E.EXE  
  
     
The LAN Manager installation will add several drivers to the 
CONFIG.SYS file. Only the MAC driver referring to a particular 
board should be replaced.   
  
The line with PROTMAN.DOS should not be modified.  
  
  
5) Modify the config.sys file to reference the Cabletron   
   adapter rather than the adapter selected during LAN Manager  
   installation.  For example, if the 3Com EtherLink II was      
   selected during a workstation installation, use a text editor
   to change the line:  
  
    DEVICE=\3OPEN\DOSWKSTA\LANMAN\DRIVERS\ELNNKII.DOS  
  
to the line:  
  
    DEVICE=\3OPEN\DOSWKSTA\LANMAN\DRIVERS\NDISPD.DOS  
     
The LAN Manager installation will add several drivers to the 
CONFIG.SYS file. Only the MAC driver referring to a particular 
board should be replaced.  The line with PROTMAN.DOS should not 
be modified.  
  
  
  
6) Modify the PROTOCOL.INI file to include an entry for the      
   Cabletron driver.  The PROTOCOL.INI file contains sections   
   defining parameters for all the protocol drivers used by LAN  
   Manager.  To add a section for this driver, use a text editor
   to add the following lines to the file:  
  
    [CSI8023]  
    drivername = CSINET$  
  
The line containing "[CSI8023]" defines the name for the  
driver and will be used in the bindings command described below.

The drivername "CSINET$" is used by the protocol manager.  
  
Other lines can be defined for the driver and can be modified  
appropriately depending on how the adapter and PC are configured. 
 
The values shown correspond to the current factory defaults for 
the supported adapters.  A more complete explanation for each of
these parameters and its appropriate values is given at the end 
of this document.       
  
  
7) Modify the PROTOCOL.INI file to change the bindings of the  
   protocol stack to reference this driver in place of the driver 
   selected during installation.  Use a text editor to modify the
   "bindings =" line to reference the "CSI8023" name defined in 
   the section added in step 3 rather than the name set during  
   installation.  
  
For example: under 3+Open with the DLC/NETBEUI protocol stack and 

 
3Com EtherLink II selected during installation, in the  
PROTOCOL.INI file section labeled "[DLC]", the line:  
  
    BINDINGS = ETHERLINKII  
  
must be changed to:  
  
    BINDINGS = CSI8023  
  
8) The installation is complete.  Reboot and bring up LAN  
   Manager using the instructions supplied by the LAN Manager  
   vendor.  

  
PROTOCOL.INI PARAMETERS  
  
Several parameters are typically specified in the CSI8023 section
of the PROTOCOL.INI file.  The only parameter that must be  
specified is the "drivername".  All the others have default  
values supplied by the driver and can be left out of the  
PROTOCOL.INI file if the installed adapter matches the default  
configuration.
