The EM935 EISA XL Adapter
----------------------------------------

   You can take advantage of Predictive Pipelining, Cogent's
   innovative data transfer technology, by using eMASTER+ adapters
   in both the client and server computers. Refer to the eMASTER+
   User Manual for information about configuring your EM935 EISA XL
   adapter for Predictive Pipelining.

   If you are using a Compaq SystemPro XL and would like to configure 
   for more than four EM935 EISA XL adapters, contact Cogent Technical
   Support.

   Cogent's NetWare 4.x Server driver is now Novell Tested and 
   Approved. The Novell Labs Report number for the EM935 EISA XL
   NetWare 4.x driver is L-2107.


EM935 EISA XL and EISA burst mode
----------------------------------------

   The EM935 EISA XL adapter is capable of supporting on some machines 
   the EISA burst mode data transfer technology for 33 MByte/sec. 
   data transfers across the bus. For compatibility reasons, the 
   EM935 EISA XL is configured by default to run in non-burst mode. 

   However, you can easily enable EISA bursting on your 
   EM935 EISA XL adapter. To configure your adapter to support bursting, 
   run the EISA configuration program for your system and edit the default 
   settings for your EM935 EISA XL adapter's 'Bus Master
   Parameters' setting. To enable bursting, change the setting from
   'Non-Burst'to 'Burst Enabled.' Enabling bursting will improve
   performance on machines which support the EISA burst mode, and
   will result in incompatibility symptoms for those machines which
   do not support bursting.


eMASTER+ Setup Program
----------------------------------------
   
   The eMASTER+ Setup Program requires MS-DOS version 3.3 or 
   later.
   
   Before running the eMASTER+ Setup Program, make sure no network
   drivers are running in the system.

   To run Diagnostics on one or more adapters, the adapters must be 
   installed in machines located on a private network.


Predictive Pipelining on NetWare 3.1x servers
----------------------------------------        
   
   To enable Predictive Pipelining, you must add the following 
   line to the STARTUP.NCF file:

   SET MAXIMUM PHYSICAL RECEIVE PACKET SIZE=4202


Predictive Pipelining on NetWare 3.1x and NetWare 4.x servers
----------------------------------------        

   You can disable Predictive Pipelining on a specific eMASTER+ 
   adapter by using MAXSIZE=1514 as a LOAD line parameter.


NetWare 3.1x and NetWare 4.x Server driver
----------------------------------------        

   To improve performance in NetWare 3.1x and NetWare 4.x 
   servers, you may increase the value of TTON, a LOAD line 
   parameter. Note that increasing TTON may result in 
   compatibility problems.

   TTON specifies in bus clocks how long the Intel 82596 chip 
   on the EM935 EISA adapter will hold on to the bus before releasing 
   it, providing no other bus mastering device requests the bus. For 
   compatibility with other bus mastering devices in the system, 
   the default TTON value is 50. To change the value of TTON, type:

   LOAD [C:] EM935_4.LAN  TTON='xx'

   Where 'xx' is a number between 20 and 5000 which indicates 
   the number of bus clocks the Intel 82596 chip will hold on to the bus.

   range: 20-5000
   default: 50


NFOLIO Help
----------------------------------------                  

   Problems are known to occur when using ODI workstation 
   drivers for bus mastering LAN adapters with NetWare's 
   NFOLIO Help versions prior to 2.13.  The NFOLIO 2.13 
   update is available on CompuServe in the Novell 
   Vendor A forum (GO NVENA).


Performance Testing and NDIS Drivers
----------------------------------------
   
   If you are using NDIS drivers and performance testing 
   your eMASTER+ adapters, use the "max" parameter in PROTOCOL.INI.
   The max parameter maximizes performance by increasing the 
   values of certain parameters. For more information, see the
   eMASTER+ User Manual.
