Section 3) Installation issues not covered in the manual
========================================================

3.1 Upgrading your Madge drivers for Windows NT
-----------------------------------------------
  
To upgrade from LAN Emulation Software release 1.0x.

a) Remove  the  existing adapter driver by using the network applet in 
   the Control Panel.   When  prompted  to  remove  entries  from  the 
   registry, do so. When prompted to restart the machine, do so.

b) After restarting the machine, use File Manager to delete  the  file 
   ATMCFG.CPL  from  the  %SystemRoot%\SYSTEM32 directory. Then delete 
   the      file       MDGATM.INI       from       the       directory 
   %SYSTEMROOT%\SYSTEM32\DRIVERS. 

c) Install the new driver by using the  ADD  ADAPTER  feature  of  the 
   NETWORK applet in the control panel. The path for the driver on the 
   Madge release disk is A:\I386\LEC.

d) Restart the PC again and the new driver will load.


To upgrade from the Beta of LAN Emulation Software release 1.10:
   
a) Remove all the existing adapter drivers (including non-ATM drivers) 
   by using the network applet in the Control Panel.  When prompted to 
   remove  entries  from the registry, do so. When prompted to restart 
   the machine, do so.

c) Install the new driver by using the  ADD  ADAPTER  feature  of  the 
   NETWORK  applet  in  the  Control  Panel.  Select 'Disk provided by 
   manufacturer' (or, for Windows NT 4.0,  select  'Have  disk').  The 
   path  for  the  driver  on  the  Madge release disk is A:\I386\LEC. 
   Install any additional drivers you require.

d) Configure  the driver in the way that you require, then restart the 
   PC. The ATM driver is now loaded.
   
   
3.2 Collage 25 drivers for Power PCs running Windows NT
-------------------------------------------------------
To obtain Collage 25 drivers for Power PCs running Windows NT, contact 
Madge  Technical  Support  (see Section 10) or download the files from 
the Madge BBS.

**********************************************************************
NOTE: Madge do not provide drivers  for the Collage 155 PCI adapter or 
      the Collage 155 PCI Client adapter in Power PC machines.
**********************************************************************


3.3 DOS and NetWare ODI Drivers
-------------------------------
The DOS and Netware server drivers are shipped on a single Madge disk.  
This  is  because  the  DOS  ATM  stack  uses some of the same Netware 
Loadable Module (NLM) files as the Netware server's  ATM  stack.   The 
Madge  installation  utility,  ATMSETUP.EXE,  loads  the NLMs into the 
DOS workstation's upper memory.

The DOS and NetWare drivers now run faster than they  did  in  release 
1.0x.  They also require less conventional DOS memory.


3.4 The Madge ATM Configuration file (MDGATM.INI)
-------------------------------------------------
The   MDGATM.INI   file   contains  important  information  about  the 
configuration of the ATM stack on a DOS, Netware or  NT  computer.  Do 
not edit this file. To make changes to your ATM configuration, use the 
Madge  ATM Manager. This program is described in Chapter 10 of the LAN 
Emulation Software Installation Guide (part number: 100-190).


3.5  DOS  and  EMM386.EXE  
-------------------------  
To  load  the Madge drivers for DOS, you must have MS DOS version 6.22 
(or above) loaded.  Also, if you are using  EMM386.EXE  you  must  use 
version 4.49 (or later); this is the first PCI-aware version of EMM386 
(it is the version that ships with DOS 6.22). 

You  can  obtain EMM386.EXE from the MS-DOS forum on Compuserve. To do 
this, go into the Forum, search the library for  EMM386, and download 
the  file  EMM622.EXE.  (This is a self extracting file which contains 
instructions on upgrading.) 


3.6 Windows 95 and EMM386.EXE
-----------------------------
Some versions of EMM386.EXE shipped with Windows 95 are not compatible 
with the Madge (ATM) DOS ODI driver (running under Windows 95 with the 
Microsoft ODI-to-NDIS mapper ODIHLP.EXE). If you are affected by this, 
the driver will lock up when the system attempts to load it. 

If you are using Windows  95,  we  recommend  you  to  use  EMM386.EXE 
version  4.49 (or later). This is the PCI-aware version of EMM386 that 
is supplied with DOS version 6.22. 


3.7 Netware VLMs and Collage 155 drivers
----------------------------------------
For best performance on DOS workstations that are using Netware  VLMs, 
we  recommend  you  to use Netware VLM Version 1.2b (or later).  These 
files are available from Novell.  Also, use the parameter MAX IPG 0 in 
the DOS Requester section of NET.CFG. This improves the  operation  of 
VLM burst mode on high speed network adapters.


3.7 UNI 3.0/3.1 compatibility
-----------------------------
This release of the LAN Emulation Software supports UNI  3.0  and  UNI 
3.1.    By   default,  the  Madge  ATM  stacks  for  DOS  and  NetWare 
automatically detect - and then use - the  version  of  UNI  signaling 
that  the  ATM  switch is using. To override this feature, because you 
want to specify either UNI 3.0 or UNI 3.1 as the type of signaling for 
the ATM stack to use, run the Madge ATM Manager (see Chapter 10 of the 
LAN Emulation Software Installation Guide; part number: 100-190). 

Note  that  the  UNI 3.0 and 3.1 interfaces are formally incompatible. 
This means that both ends of every connection must be either  UNI  3.0 
or  3.1.  If they are not, then the signaling VCC might appear to come 
up correctly - depending on your switch - but in fact it will not have 
done: point-to-multipoint connections will not work.   In  this  case, 
however,  all  the  workstation  user  will  see is the error message: 
'CONNECT to LECS failed'. 


3.8 Netware server memory requirements
--------------------------------------
A  Netware  server  driver  needs  approximately  2MB  of RAM for each 
adapter in the server.  Each instance of LAN emulation  services  that 
you  run  on  an  adapter  requires an extra 2MB of RAM over and above 
this.


3.9 Netware version 3.1x
------------------------
Netware 3.11 requires updated modules for LSLENH,  TOKENTSM,  ETHERTSM 
and  CLIB.  These  are  available  from  Madge  Technical Support (see 
Section 10).

For Netware 3.12, ensure that the server contains  at  least  32MB  of 
RAM, and add the following line to AUTOEXEC.NCF:
 
SET MAXIMUM ALLOC SHORT TERM MEMORY = 4000000


3.10 Japanese DOS
-----------------
If you are using Japanese DOS  and  you  experience  problems  loading 
MATM,  edit  the  CONFIG.SYS  file  so  that  $FONT.SYS  loads  before 
HIMEM.SYS.


3.11 OS/2: support for Token Ring LAN emulation only
----------------------------------------------------
The current release of the OS/2 LAN emulation software  does not support 
Ethernet  LAN  emulation,  and  it  does  not  support the Collage 155 
adapter.  Support is provided  for the Collage 155  PCI Client and the 
Collage 25 adapters only. 

   
3.12 Running diagnostics 
------------------------
The manual suggests that you cannot run ATMDIAG  for  Windows  NT  and 
OS/2.   This  is  true, because it does not work under these operating 
systems. However, you can run diagnostics on any PC: just boot it from 
disk 1. 


Section 4 Installing the LAN Emulation Software (summary)
=========================================================

For full  information  about  installing  the  ATM  drivers  for  your 
environment,  refer  to  the LAN Emulation Software Installation Guide 
(part number 100-190). 


4.1 Run diagnostics first
-------------------------
Before  installing  the drivers, run the ATMDIAG utility to check that 
the adapter is working correctly. To do this, put  disk  1  into  your 
floppy  drive  and  either  reboot  the PC or run ATMDIAG from the DOS 
prompt. If you wish to copy the diagnostics program to your hard disk, 
ensure that you copy the help and data files as well. There are  three 
files in all (see Section 2).


4.2 DOS ODI workstations
------------------------------
Put the DOS ODI disk (disk 2) into the floppy drive and  run  the  ATM 
installation  program  called  ATMSETUP.EXE. This installs all the DOS 
ATM software to your hard disk and configures the ATM stack.  You will 
need to load EMM386.EXE from CONFIG.SYS (see Section 3.5).

To connect to a server running LAN emulation, type:

         MATM 
         LSL    
         ATMODI (token ring ODI driver, ATMODIE for ethernet)
         IPXODI
         VLM (or NETX)

MATM and the above commands can be incorporated into your STARTNET.BAT 
file or your AUTOEXEC.BAT file.

Use the program called ATMMGR.EXE to make changes to the configuration 
of  the  ATM  stack  (see  Chapter  10  of  the LAN Emulation Software 
Installation Guide, part number: 100-190). 


4.3 Netware server 3.1x/4.1x
----------------------------
For NETWARE put the following commands into your  AUTOEXEC.NCF:

                LOAD MATM
                START ATM
                          
To load the ODI driver for Token-Ring LAN emulation, type:

                load ATMODI                  
                bind ipx ATMODI net=nnn      (nnn== net number)

To load the ODI driver for Ethernet LAN emulation, type:

                load ATMODIE                  
                bind ipx ATMODIE net=nnn      (nnn== net number)

To  load different frame types, use the FRAME= parameter when you load 
the driver.  For example, for ethernet_snap frames, type:

                load ATMODIE frame=ethernet_snap name=<board name>
 
For further information about Netware 3.11 servers, see Section 3.9.


4.4 Windows NT
--------------
Select  the  network  icon  in  the  control panel and then select Add 
Adapter.  When asked for the adapter type,  select  the  option  'Disk 
provided  by  manufacturer'. Insert disk 3 into the floppy disk drive. 
The drivers for the LEC are stored in the directory  A:\I386\LEC.   To 
configure  the LEC, follow the instructions on the screen.  If you are 
installing LAN emulation services as well, install the LEC first.

If you are installing this  driver  to  upgrade  an  existing  driver, 
see Section 3.1.

To  install LAN emulation services on an NT workstation, first install 
the LEC, then select Add Software  from  the  network  applet  in  the 
Control Panel. Select '<Other> requires disk from manufacturer'.  When 
prompted  for  a disk, insert the Madge disk containing the NT drivers 
and specify the path A:\I386\LANE. See note below.

**********************************************************************
NOTE: LANE services  under  Windows  NT  are  only  supported  for the
      Collage 155 PCI  Adapter and not for the  Collage 25 PCI Adapter
      or the Collage 155 PCI Client adapters.
**********************************************************************


4.5 OS/2 Warp
-------------

**********************************************************************
NOTE: The  OS/2  drivers  in  this  release  support  Token  Ring  LAN 
      emulation only,  and  they are only available for the Collage 25
      PCI and the Collage 155 PCI Client adapters.
**********************************************************************

The installation method depends on whether you are installing for OS/2 
Warp, Warp Server, or Warp Connect.


For OS/2 Warp or OS/2 ver. 2.11 :

a) Install OS/2 Warp onto your machine first.
b) Use  LAPS  to install the ATM driver.

After  following the OS/2 driver  installation instructions  and before 
rebooting the machine open an OS/2 windows - check that disk 4 is still
inserted and run 

        a:mdgatm.cmd <param1> <param2>

where <param1> can be 'col25' or 'col155client'

and <param2> can be either 'UNI3.0' or 'UNI 3.1'

this copies the ATM configuration files to the hard disk. You  may use 
this MDGATM.CMD  utility to change  your configuration  between UNI3.0 
and UNI 3.1 or  if you change  the type of  adapter in  your PC. After
running  MDGATM.CMD  you must reboot your OS/2  workstation before the 
changes take effect.


For Warp Server :

Install the driver at the point in the OS/2 installation  procedure 
where  you  are  prompted  to  do so. When you do this, some of the 
files you need  do  not  get  copied  across.   Continue  with  the 
installation  process and ignore any error messages relating to the 
network driver. 

After  finishing the Warp Server installation open an OS/2 window.
Insert disk 4 and run 

        a:mdgatm.cmd <param1> <param2>

where <param1> can be 'col25' or 'col155client'

and <param2> can be either 'UNI3.0' or 'UNI 3.1'

this copies the ATM configuration files to the hard disk. You  may use 
this MDGATM.CMD  utility to change  your configuration  between UNI3.0 
and UNI 3.1 or  if you change  the type of  adapter in  your PC. After
running  MDGATM.CMD  you must reboot your OS/2  workstation before the 
changes take effect.


For Warp Connect:

You can install netowrking support at warp connect installation time.
In this case the machine will reboot  (as it should) however  not all 
the  ATM files will  have been copied.  In this case  just follow the 
instructions for running the mdgatm.cmd below.

If you have installed Warp Connect without network support, run
PRODINST from the root of the Warp CD and follow the instructions for
installing drivers. 

After following the OS/2  driver  installation instructions  and before 
rebooting the machine open an OS/2 windows - check that disk 4 is still
inserted and run 

        a:mdgatm.cmd <param1> <param2>

where <param1> can be 'col25' or 'col155client'

and <param2> can be either 'UNI3.0' or 'UNI 3.1'

this copies the ATM configuration files to the hard disk. You  may use 
this MDGATM.CMD  utility to change  your configuration  between UNI3.0 
and UNI 3.1 or  if you change  the type of  adapter in  your PC. After
running  MDGATM.CMD  you must reboot your OS/2  workstation before the 
changes take effect.

If  you  are  using  the FORE ASX200 switch with Forethought 3.4.2 (or 
higher) and with FORE line  cards  rev.C  (or  later),  configure  the 
Collage  adapter  to  run  in loopback mode.  Do this from the Adapter 
Configuration window in the Madge ATM  Manager.  The  ATM  Manager  is 
described  in  Chapter  10  of the LAN Emulation Software Installation 
Guide (part number: 100-190).  If you  run  the  adapter  in  loopback 
mode,  software  modules inside the computer can communicate with each 
other without using the switch.

If  you are using the Bay Lattiscell switch, use build 35b or later of 
the LCMS software.

For the Newbridge switch use software version 41111F3.01 or later.


Section 6) Changes in this release
==================================

6.1 General changes and improvements
------------------------------------

1) This release  includes support for the Collage 155 PCI Client adapter.
   The  Collage 155 PCI Client  is a low cost 155Mbps  adapter  designed
   specifically for client machines.  Software support is  provided  for
   DOS ODI, Netware Server, Windows NT and OS/2. Whilst the adapter will
   work in file server environments  (Netware, Windows NT, OS/2) its use
   in  these  environments  is not  recommended  as its  host  processor
   utilisation  will be  high.  The  Collage 155  PCI Adapter  has  been
   specifically designed for servers and will deliver superior performance.

2) The Installation and mamagement utilities have been changed to include
   support for the Collage 155 PCI Client adapter.

2) This release includes OS/2 support for OS/2 2.11 as well as OS/2 Warp.
   OS/2 support is still limited to the Collage 25 and Collage 155 Client
   adapters only and only Token Ring LECs.

3) Support for UNI 3.1 has been added to the OS/2 drivers.

4) The ATMODIE.LDI Netware server driver install file has been changed to
   list the correct frame types for an ethernet driver,

5) ATMDIAG.EXE  has  been  modified to improve the diagnostic information
   presented to the user. In particilar a warning has been introduced if
   the PCI BIOS latency timer is less than 32. A low latency timer value
   had been diagnosed as the cause of several performance problems in
   certain machines.

6) Diagnostic  information  has  been  added  to the OS/2 driver which is
   spooled  to  the  lantran.log  file.  Information  such as adapter up,
   signalling up, etc is now available for diagnostic use.

7) The OS/2 and Windows NT drivers have been changed to give the correct
   byte ordering for LEC ID numbers.  This changes is cosmetic only  and
   would  only be  noticed by network  engineers diagnosing ATM  network
   problems with ATM protocol analysers.

8) ATMMGR.EXE  and  ATMMGR.NLM have  been modified  to remove  a  memory 
   limitation problem that could cause them to crash under very exceptional
   conditions.

9) ATMMGR.EXE has been changed such that it does not display the ring 
   number for ethernet ELAN properties.


Section 7) Known problems and operating restrictions
====================================================

7.1 General problems
--------------------
1) On some computers a soft reset does not reset the ATM adapters. You
   might have to power the computer down for a couple of seconds. 

2) The Collage 25 PCI and the Collage 155 PCI Client adapters have  not
   been designed for use as server adapters. Although you can use them,
   for example, in a NetWare server, their processor utilisation can be
   very high. We recommend  you to use the Collage 155 adapter instead. 
   Indeed,  to maximise aggregate throughput,  we recommend you to  use
   multiple Collage 155 adapters in NetWare servers.   
   

7.2 Problems with Netware servers
---------------------------------
1) Netware  3.11  requires updated modules: LSLENH, ETHERTSM, TOKENTSM 
   and CLIB. These are  available  on  request  from  Madge  Technical 
   Support.

2) There are  problems  running  the Collage 155 PCI adapter  in  some 
   low-performance  servers  (that  is, in Pentium computers with less 
   than 60MHz of processor power). Under heavy traffic, cells  can  be 
   dropped and the SSCOP signaling transport protocol can time out for 
   short  periods.   If  you  are  using  a  Collage  155  adapter, we 
   recommend you to use a server with  a  60MHz  (or  faster)  Pentium 
   processor.

3) On  a  3.1x  Netware  server  LAN emulation can run out of physical 
   memory.  We recommend that you run  LAN  emulation  services  on  a 
   server  with at least 32MB of RAM and with at least a Pentium 60MHz 
   processor.   Also,  add  the  following  line   to   your   Netware 
   AUTOEXEC.NCF:

   SET MAXIMUM ALLOC SHORT TERM MEMORY = 4000000

4) If  you  encounter  problems  loading the ATM drivers in a computer 
   that also contains a  Madge  Smart  Ringnode  (for  example,  in  a 
   MultiProtocol  Router  environment), please contact Madge Technical 
   Support for  a  Token-Ring  driver  which  is  optimised  for  this 
   configuration.
   
   
7.3 Problems with the DOS ODI drivers
-------------------------------------
1) On some PCs that run the Japanese version of  DOS,  MATM  does  not 
   load.  If  you  experience  this  problem,  edit CONFIG.SYS so that 
   $FONT.SYS loads before HIMEM.SYS.


7.4 Problems and restrictions with the OS/2 drivers
---------------------------------------------------
   
1) Only one adapter is supported per machine.

2) Only one LEC is supported per adapter.

3) Only Token-Ring LECs are supported. Ethernet support will be added
   in a future release.

4) The Collage 155 PCI Adapter is not supported for OS/2 in this release.

5) There is no SMP machine support for OS/2 in this release.

6) OS/2 versions prior to version 2.11 are not supported.

7) There is no LANE management  tool for OS/2  in this  release. This
   tool will be available in a future release. All supported options 
   can be configured by the installation utility.

8) IPX/SPX protocols can be configured under OS/2 and may work in some
   environments although full support for IPX/SPX cannot be guaranteed
   in this release.
