    TITLE:  Bravo MS and Olicom PCI 3137 Token Ring

    ISSUE

       When using an Olicom OC-3137 PCI Token Ring adapter in a Bravo MS
       system, the unit may lockup after loading the 32-bit LAN driver
       under Novell’s 32-bit DOS client. This issue only affects
       Olicom’s 32-bit LAN driver and the following systems: 501951,
       501952, 501954, 501955, 501956, 501972, and 503043.

    BACKGROUND

       N/A

    ACTION

       To resolve the issue, upgrade to Olicom’s Token Ring driver,
       version 4.04, and add a NOISAPNP parameter to the OCTOK162.LAN
       driver line, in the STARNET.BAT file. Follow the instructions
       below:

       1. Copy the TRNW4X.EXE to a temporary subdirectory and
          extract the file.

       2. Install the Netware Client32 program according to
          Novell’s instructions. When prompted for a LAN driver,
          change the driver path to the directory created in
          step # 1.

       3. When the client installation is complete, modify the
          STARTNET.BAT file located in the C:\NOVELL\CLIENT32
          directory to add the NOISAPNP command parameter as
          follows:

           C:\NOVELL\CLIENT32\OCTOK162.LAN NOISAPNP FRAME=XXX

           where XXX is the original token ring frame type used.

       4. Restart computer.

       This parameter will DISABLE the driver from looking for a
       Plug-and-Play ISA card and is also not valid on earlier driver
       versions.

       Obtain the 4.04 driver, filename TRNW4X.EXE, from Olicom’s Web
       site at the following address:

                         www.olicom.com
