READCMGR.TXT file for NSD #1
                        NetWare Requester for OS/2 V1.3

This file contains instructions for using the CMGRLAN driver shipped on NSD #1.
For information about using NSD #1 or about what is contained on NSD #1, please
read the READNSD.TXT file in the same location as this file. 

The CMGRLAN.SYS driver replaces the TOKENEE.SYS driver.  CMGRLAN.SYS works with IBM
Ethernet, IBM PC, and Token-Ring networks using Extended Edition Communications
Manager. If you are running OS/2 Extended Edition, you should use this new 
driver.  Modify your CONFIG.SYS file to replace TOKENEE with CMGRLAN.  

The following are special considerations for the CMGRLAN driver:

      - The Link Driver option in your NET.CFG file should specify the 
        correct frame type for the network board you are using with CMGRLAN. 
        If NET.CFG specifies a different type, the NET.CFG setting will be 
        ignored and the frame type will default to the correct default setting 
        for your board.

      - Because CMGRLAN works with PC-Network (PCN), Ethernet, and Token-Ring 
        networks, Source Routing is now a separate module instead of being 
        built into the driver as it was with TOKENEE. To use source routing 
        with PCN or Token-Ring networks, remove the REM from the line in your 
        CONFIG.SYS file that loads ROUTE.SYS, exit CONFIG.SYS, and reboot 
        your machine. Do not load ROUTE.SYS if you are using Ethernet. 

      - When using CMGRLAN with Ethernet, use the Link Driver option in NET.CFG
        to specify the node address of your network board.  If you do not 
        specify the address or if you specify the wrong address, after 
        initialization you will see an error message indicating the correct
        address.

      - IBM's Communications Manager allows you to specify either the 
        Ethernet DIX or the Ethernet 802.3 frame types, but not both. 
        (Selecting Ethernet 802.3 also allows you to send/receive Ethernet 
        802.3, 802.2, or SNAP packets.) Because Communications Manager does not 
        allow a DIX frame type and another Ethernet frame type together, 
        the NET.CFG setting for CMGRLAN does not allow this combination either.
        
        To send/receive DIX packets, specify only Ethernet_II as the frame 
        type in NET.CFG (and select Ethernet DIX in Communications Manager); 
        to send/receive other types of Ethernet packets, specify either 
        Ethernet_802.3, Ethernet_802.2, or Ethernet_SNAP (and select 
        Ethernet 802.3 in Communications Manager).  

      - Because of IBM's implementation of Ethernet for Communication's 
        Manager, you cannot currently run Multicasting when using CMGRLAN for 
        Ethernet. If you load a Multicast Address, you will see an 
        OUT_OF_RESOURCES error.

      - You can use NET.CFG to select which network board you want the 
        CMGRLAN driver to control. Use the Link Driver option with either the
        PRIMARY or ALTERNATE parameter.  (PRIMARY is the default.)  For 
        example, to use your alternate network board, type the following 
        in NET.CFG:

                  Link Driver CMGRLAN
                        Alternate
