DRIVER FIXES - IBM 16/4 TOKEN RING ADAPTER II - Feature Code 5120
=================================================================

Drivers TOKENBM.COM and IBM16TR.DOS have been updated to fix the
following problems and information on usage:

* DOS/LSP Environment

  -  Neither the IBM16TR.DOS MAC Protocol Driver nor PROTMAN.DOS
     can be loaded into the UMB area.  If these items are loaded
     HIGH, the adapter will fail.

  -  The Lan Support Program V. 1.3 device drivers;

         DXMA0MOD.SYS
         DXME0MOD.SYS
     or  DXMT0MOD.SYS

     can be loaded high using the 'DEVICEHIGH=' statement when using
     version 2.00.02 of the IBM16TR.DOS.


*  Novell Netware Environment

   - Default I/O BASE ADDRESS not usable by TOKENBM.COM:
     The default I/O BASE ADDRESS as set in the switches of the adapter
     and the NET.CFG file is 86A0.  The I/O BASE ADDRESS must be changed
     to F6A0 both in respect to the switches on the card and the NET.CFG
     file.  The new switch settings should be: SW #1-OFF, SW #2-OFF,
     Sw #3-off.  The new NET.CFG file should use the following parms:

     link driver tokenbm
          port F6A0
          enhanced yes

     This problem has been fixed in version 2.35 of the TOKENBM.COM
     driver.

   - Adapter fails to insert into ring under heavy traffic conditions:
     When using the TOKENBM.COM driver and attempting to insert into
     a ring under heavy traffic conditions, the adapter will intermit-
     tently fail to insert into the ring.

     This problem has been fixed in version 2.35 of the TOKENBM.COM
     driver.


*  'DMA MODE NOT SUPPORTED' message appears when using the (TOKENBM.COM
    or IBM16TR.DOS) driver and EMM386 memory manager.  Adapter
    fails to initialize:

     This problem has been fixed in version 2.35 of the TOKENBM.COM
     driver and version 2.00.02 of the IBM16TR.DOS driver.


*  IBM ValuePoint machines:
   -  Some models, if not all, of the ValuePoint machines use
      interrupt levels 2 and 9 for their disk drives.  The default
      interrupt level for the 16/4 Adapter II is IRQ 9 (Sw #4-on, and
      Sw #5-on).  You must change the interrupt level of the adapter
      to avoid conflicts.  See the Adapter Installation Manual that
      ships with the adapter for instructions on changing the IRQ
      level.
