Summary
-------

This  file  tells  you  how to configure the MDGMPORT.SYS driver under 
Windows95. It also provides troubleshooting information.

  
Section 1) Advanced Configuration
---------------------------------
To set parameters for the Miniport driver, choose the Networks  option 
from the Control panel.  Highlight the Madge adapter in the components 
list.  Select Properties. Then click on Advanced.

You  will  see  a  list  of options, each of which is described below.  
Once you have finished setting options, click on OK., Then click again 
on OK in the Networks dialog box.

The options are as follows:

Ringspeed
---------
The CardBus adapter has a factory default ring speed  of  16Mbps.  You 
can  alter  the  ring  speed  to 4Mbps by running the Madge Token Ring 
Configuration program, TRCFGC.EXE. Alternatively, you can override the
ring speed configured at the adapter by using this driver option.


LAA
---
Normally a token-ring adapter uses an address that is  stored  on  the 
adapter.   However,  you  can  set  a different, locally administered, 
address bu using the LAA option.  The address you specify must be a 12 
digit, hexadecimal number in the range 400000000000 to 7fffffffffff.


Maximum Frame Size
------------------
This option allows you to set the maximum frame size for the adapter.


Transfer Type
-------------
On some adapters there are several different ways of transferring data 
between the computer and the adapter. This option allows you to choose 
which method to use. The options avaialable for  the  CardBus  Adapter 
are "PIO" and "DMA"



Watchdog
--------
Normally,  MDGMPORT closes down an adapter when instructed to do so by 
the operating system.  Under almost  all  circumstances  this  is  the 
correct  behaviour.   However, if the computer hangs, then the adapter 
will not be closed down until the computer is  powered  off.   To  get 
around  this problem, insert the word "Watchdog" into the registry and 
give it a non-zero value.  This  causes  the  adapter  to  close  down 
automatically  if  the  computer  does  not  respond for the number of 
seconds that you specify. We recommend a period of 15 seconds.


Section 2) Troubleshooting
--------------------------

If you start Windows 95 and a message appears saying that  your  Madge 
adapter is not working, then you must start an MS-DOS session and type 
the command:

    TYPE C:\WINDOWS\NDISLOG.TXT

(This assumes that C:\WINDOWS is the directory that you have installed 
Windows95 into.) 

You will see some text like:

Madge 16/4 CardBus Adapter (0001). Error Code = AAAAAAAAAA, ....

To find out  the  meaning  of  each  value  of  AAAAAAAAAA,  read  the 
ERRORS.TXT file.


Section 3) Hardware Initialization Error Codes
----------------------------------------------
If the adapter fails because of a hardware initialization problem, you 
can use the PP and QQ values in the error report to determine why.

Some of the common errors are explained in the file ERRORS.TXT. If the 
QQ value in your case does not match  any  of  the  values  listed  in 
ERRORS.TXT,  contact  MADGE  technical  support.  Quote  the PP and QQ 
values in the error reported to NDISLOG.TXT.
