    TITLE:  Madge Token Ring Adapter & Bravo MS-T

    ISSUE

       The Bravo MS-T system may experience a resource conflict when
       installing a Madge 16/4 Token Ring ISA Client Plug-and-Play Ring
       Node (RN) adapter in a Bravo MS-T 6200 and 6180.

       This issue applies to the following systems: 503057 and 503058.

    BACKGROUND

       The conflict occurs between the integrated Crystal audio chip and
       the Madge 16/4 Token Ring ISA Client PnP RN adapter.

    ACTION

       To resolve this issue, follow the instructions below.

       1.  Click on the 'Driver for Windows 95' and download
           file WIN95.EXE from Madge’s ftp site at

           ftp://ftp.madge.com/anonymous/pub/adapters/tok_rng
           /lss/lss5.0/lss50.htm

       2.  Double-click on the file WIN95.EXE and extract the
           contents to a floppy diskette.

       3.  Go into Device Manager in Control Panel and verify
           that there are no conflicts. If the Madge Token Ring
           adapter is listed, remove it. Do not reboot the
           system at this time.

       4.  Copy files NETMADGE.INF, MDGMPORT.BIN, AND
           MDGMPORT.SYS, included in WIN95.EXE to the
           Windows\System subdirectory. Exit Windows 95.

       5.  Verify that the Madge card is connected to a Token
           Ring concentrator or MAU.

       6.  Insert Disk 1 of the Madge LAN support software v4.32,
           or later, into floppy drive A:

       7.  Reboot the system.

       8.  The Madge configuration screen should appear. If it
           does not, type TRCFG.EXE at the DOS prompt and press
           the [Enter] key.

       9.  Press the [F3] key to "configure any s/w configurable
           ringnodes".

       10. Press the [Enter] key to start.

       11. Press the [Enter] key again.

       12. Using the [Tab] key to navigate, change the settings
           to the following:

               I/O Port      0A40
               Interrupt     10
               Ring Speed    Set according to network speed
               Mode          Non-PNP (Locked)

       Note: By locking the configuration, Windows 95 will be
             unable to change these settings. If any other
             adapter uses the above settings, change them as
             required.

       13.  Press the [F4] key.

       14.  Press the [F4] key to update the configuration

       15.  Enter the Diagnostics area.

       16.  Run the Standard Diagnostics to verify that all
            tests pass.

       17.  Remove the diskette from drive A:

       18.  To clear memory, turn the system OFF, wait ten
            seconds, and then turn the system ON again.

       19.  Boot the system to Windows 95. Windows 95 will see
            the adapter and install the drivers. You may be
            prompted for the Madge disk. Use the floppy diskette
            that you prepared in step 2 above.

       20.  Open Device Manager and verify that there are no
            conflicts.

       21.  Also verify that the three drivers you originally
            copied into the Windows\System subdirectory are the
            same. You can do this by comparing the dates on each
            of the files.

       Your adapter is now installed and configured properly.
