                       NDIS Drivers Installation Notes

 This file contains instructions on installing NDIS drivers for the
 network operating systems listed below.

 -  Microsoft LAN Manager
 -  IBM Lan Server
 -  DEC Pathworks
 -  Banyan VINES
 -  Other NDIS-based installations

 Microsoft LAN Manager versions 2.0, 2.1, and 2.2

 The EtherDisk diskette contains a subdirectory structure and files that make 
 it an OEM import disk for the LAN Manager installer.  Use the import function 
 of the LAN Manager installer to capture the NDIS driver from the EtherDisk 
 diskette.  Be sure to save the new configuration before exiting the installer.

 IBM LAN Server

 This EtherDisk diskette contains Ethernet driver import files for 
 IBM LAN Server.

   IBM LAN Server 3.0

   IBM LAN Server 3.0 contains an installer for both OS/2 (LAPS) and DOS 
   (DXMAID).  Both of these installation utilities fully support OEM network 
   adapter driver import capability.

   DOS Installation

   Run the DXMAID installer from the IBM LAN Support diskette.  Use the 
   defaults from the first menu.  The second menu prompts you to enter the 
   drive and path for the import diskette.  Remove the LAN Support diskette, 
   put the 3Com EtherDisk diskette in the drive, and type A:\NDIS\DOS for the 
   drive and path.  The installer will pause after it copies the files needed 
   from the EtherDisk diskette.  Place the LAN Support diskette back in the 
   drive, and continue the installation.

   OS/2 Installation

   Run the LAPS installer from the LAN Adapter and Protocol diskette.  From 
   the second menu, select the Install option.  LAPS then installs itself and 
   other files, and returns to the second menu.  Select Install again.  On the
   next menu, LAPS prompts for a drive and path for installation.  Remove the 
   LAPS diskette and insert the EtherDisk diskette in the drive.  Type 
   A:\NDIS\OS2 for the drive and path.  LAPS will copy the needed files from 
   the EtherDisk diskette.  When the acknowledge message appears at the end of
   the copy, reinsert the LAPS diskette and continue with the installation.

 IBM LAN Server 2.0

 LAN Server 2.0 is not as sophisticated as LAN Server 3.0.  Installation can 
 be done successfully, but manual intervention is required.  In all cases, the 
 user is required to edit files.  For OS/2, the E editor is fine.  For DOS, use
 either EDLIN or EDIT.

   DOS Installation

   Run the DXMAID installer from the LAN Support diskette.  Specify the 
   Ethernet adapter installation from the menu.  When DXMAID is completed, do 
   the following to complete the installation.

   1. Copy the EtherLink/MC NDIS driver to the hard disk.  Type:

   2. Edit the CONFIG.SYS file.
      a. Change the line:
         device = \LANMAN\PROTMAN.DOS
         device = \LANMAN\PROTMAN.DOS /I:\LANMAN
      b. Change the line:
         device = XX.DOS
         device = \LANMAN\ELNKMC.DOS
      c. Save the file and exit the editor.

   3. Enter the LANMAN subdirectory.  Type:

   4. Edit the PROTOCOL.INI file.
      a. Four lines after the line [ETHERNET], change the line:
         Bindings = IBMAC 
         Bindings = TCMAC2

      b. Save the file and exit the editor.

   The installation is complete.  The LAN Support program activates the next 
   time the machine boots.

   OS/2 Installation

    - Insert the IBM OS/2 Requester Diskette #1 and run the LANINST
      installation program.  Select Advanced Installation on the next menu.  
      Select "Install or Configure this Workstation" option.  Follow the
      "Install or Remove a Component" option choices. 

    - Follow the "Configure" menu.  Insert the OS/2 Network Adapter Drivers
      diskette when the prompt appears.  After LANINST has completed copying
      the files from the Network Adapter Drivers diskette select the 
      Configure Workstation option from the next menu.  

    - The next menu prompts for the drive and path for the additional drivers.
      Insert the EtherDisk diskette and type A:\NDIS\OS2.  LANINST copies the 
      appropriate 3Com adapter files to the hard disk and returns to the 
      options menu.  
    - In the Configure Workstation Menu it prompts for adapter and protocol
      options.  In the adapters window, page down until the 3Com EtherLink 
      Family OS/2 menu item appears.  Select this item and continue the 
      installation.  When the installation is complete, exit the installer.

 DEC Pathworks

 To install DEC Pathworks version 4.1 on a DOS NDIS workstation, DOS must be 
 installed on the target workstation C: drive, or you must have a bootable
 DOS floppy.  Follow these steps:

 1. Insert the version 4.1 DOS Client Setup diskette in your floppy drive.

 2. Change to that drive and execute the NETSETUP.EXE program.

 3. Press [Ctrl]+[F10] twice to change to advanced-operator mode.

 4. Follow the screens to select a Transport Protocol.

 5. Insert the appropriate diskettes for the selection you made in step 4.

 6. Select your network adapter by typing ETHERNET or TOKEN-RING.
 7. Select the option (OTHER NDIS) adapters.

 8. When prompted for the DRIVE:\PATH\FILENAME for the NDIS driver, type:


 9. When prompted for the full DRIVE:\PATH of the PROTOCOL.INI fragment,


 10. Follow the rest of the installation screens and the procedure for writing
     the KEY DISK.

 The NETSETUP program will build the PROTOCOL.INI file for you and modify your
 startup files to use the adapter you have selected.

 NOTE:  If you are using a 16-bit adapter in DOS Pathworks, you must add the
        /N parameter to the line in the STARTNET.BAT file that starts the 
        network scheduler.  The line usually looks like:

        %BOOT%\DECNET\sch /h

 Banyan VINES

 To install VINES 5.0 software on a DOS NDIS workstation, follow these 
 instructions.  DOS must be installed on the target workstation C: drive, or
 you must have a bootable DOS floppy.

 1.  Use the DOS MD command to create a subdirectory called \VINES.

 2.  Copy the contents of the VINES LAN S/W (DOS) Install diskette into the
     \VINES subdirectory.

 3.  Copy the contents of the NDIS subdirectory on the VINES LAN S/W (DOS) 2
     of 2 diskette into the \VINES subdirectory.

 4.  Copy the PROTOCOL.INI fragment from the NDIS\DOS subdirectory on the
     EtherDisk diskette to the \VINES subdirectory.

 5.  Edit the PROTOCOL.INI file to read as follows:



 6.  Run the PCCONFIG.EXE program located in the \VINES subdirectory.

 7.  Select option 1, Network Card Settings.

 8.  Select the NDIS Ethernet option.

 9.  The NDIS workstation screen appears.  Enter the IRQ that you selected 
     for the EtherLink/MC adapter.

 10. Edit the CONFIG.SYS file and add the following lines, substituting A:
     for C: for a floppy disk installation.


 11. Add the BAN command to the AUTOEXEC.BAT file.  BAN loads the NDISBAN
     drivers and reads the PCCONFIG.DB file to invoke changes made during the
     PCCONFIG stage.

 Other NDIS-based Installations

 Under this NDIS subdirectory are the directories DOS and OS2.  These 
 directories contain the 3Com adapter NDIS driver and PROTOCOL.INI fragments 
 for DOS and OS/2.  Use these files to install the NDIS driver and create your 
 own PROTOCOL.INI file.
