***************************
*  CONFIGURING THE TC4047 *
*************************** 

To select options for the TC4047 adapter, you need the following:

     1)   You need to know the name and location of your computer's EISA
          configuration program.

     2)   The configuration file, named !TCO4047.CFG, located in the 
          EISA.CFG directory of this diskette.  For easier installation, 
          copy this file to the same directory as your EISA configuration
          program.

After locating both of the above, switch to the drive and directory where
your EISA configuration program is located and start the program.  

     *******************************************************
     *                       NOTE                          *
     * Because there are a large number of EISA            *
     * configuration programs, and they all function       *
     * differently, this section does not include specific *
     * instructions for using them.  Consult the           *
     * documentation provided with the program you have,   *
     * or its online help, for instructions.               *
     *******************************************************


The TC4047 has four configuration options:  Interrupt Request (IRQ) Mode,
Remote Reset ROM, Ring Speed and EISA Burst Mode.  Select the option you wish
to change by pressing <Enter> or another key, as required by your EISA
configuration program.  

Each TC4047 option is explained below:

INTERRUPT REQUEST (IRQ) MODE
     Options:   Non-Shareable IRQ
     Resources:     2(9)  Trigger:Edge
                    3  Trigger:Edge
                    5  Trigger:Edge
                    7  Trigger:Edge
                    10  Trigger:Edge
                    11  Trigger:Edge
                    12  Trigger:Edge
                    15  Trigger:Edge

The Non-Shareable IRQ option means that the IRQ line selected for the TC4047
cannot be used by any other device in the computer.  To change the IRQ line
used by TC4047, select the Edit or View Resources option.  


REMOTE RESET ROM
     Options:  Disabled
     Resources:  None

This option is reserved for future development.


RING SPEED
     Options:  16Mbps (default), 4Mbps
     Resources:  None

Select the ring speed of the network the TC4047 will be attached to.  

****************************************************************************
                              CAUTION
All adapters connected to a token ring network must be set for the same ring
speed.  Failure to do so will result in the adapter being removed from the
network, and will disrupt the network.
***************************************************************************


EISA BURST MODE
Options:  Enabled (default), Disabled
Resources:  None

For best performance, use the default Enabled selection, which allows the
TC4047 to use EISA burst mode data transfers.  Select Disabled if your
computer does not support EISA burst mode, or if you experience unreliable
performance with the default Enabled setting.



****************************************
*  NETWARE SERVER DRIVER FOR:          *
*     - NetWare 4.x servers            *
*     - NetWare v3.1x servers          *
*     - NetWare SFT III v3.11 servers  *
****************************************

TCTOK47H.LAN, located in the NW_SERVR directory on this diskette, is a high
performance server driver designed to work with NetWare 4.x.  This driver
can also be used in NetWare v3.1x servers and servers running NetWare SFT III
(System Fault Tolerant Level III) v3.11.  

***********************************************************************
*                           CAUTION                                   *
*                                                                     *
*   Due to hardware changes on the TC4047 adapter, TCTOK47H.LAN v1.11 *
*   or higher must be used.  This version of the driver is backwards  *
*   compatible with older revisions of the TC4047.                    *
*                                                                     *
***********************************************************************


MODIFYING STARTUP.NCF
========= ===========

The TCTOK47H.LAN driver requires a minimum of 36 Packet Receive Buffers per
TC4047 adapter configured in your NetWare server.  Insert the following
command in the server's STARTUP.NCF file (change an existing value only if it
is less than the minimum shown below):

     SET MINIMUM PACKET RECEIVE BUFFERS = (36 * number of TC4047s)

For example, if there are three TC4047 adapters in the server,
you would enter the command shown below (change an existing value
only if it is less than 108):

     SET MINIMUM PACKET RECEIVE BUFFERS = 108


INSTALLING THE DRIVER
========== === ======

Install the driver using the instructions in Chapter 6 of the TC4047 16/4
Token Ring Adapter/EISA Installation Guide.

NetWare 3.12 servers only:  When installing TCTOK47H.LAN in a file server
running NetWare v3.12, it is necessary to use the support NLMs located in the
directory named \NW_SERVR\NW386SUP on this diskette only if the versions of
your existing NLMs (named MSM31X.NLM and TOKENTSM.NLM) are prior to v2.20. 
If the versions of MSM31X.NLM and TOKENTSM.NLM are above v2.20, do not use
the NLMs on this diskette.

To find the versions of currently-running NLMs, type MODULES at the server
console command prompt.


******************************
* DOS ODI WORKSTATION DRIVER *
******************************

The DOS ODI workstation driver, named TCTOK47.COM located in the directory
DOSODI on this diskette, can be used to connect the TC4047 to networks
running NetWare v3.x or v4.x.  This section explains how to install the
driver automatically using the NetWare v4.x Client Install program; or
manually to either NetWare v4.x or v3.x networks.


==========================================
  INSTALLATION PROCEDURE - NETWARE V4.x 
  (AUTOMATIC INSTALLATION VIA INSTALL   
  PROGRAM)                              
==========================================

This section shows the essential steps for configuring the driver
on a workstation attached to a network running NetWare v4.x, using the 
Installation program provided with NetWare.  To install the driver manually,
see the next section, titled "Installation Procedure - Manual Installation".

In some installations, other steps might be required; for more
information, consult your Novell documentation.  

     *******************************************************
     *                       NOTE                          *
     * The DOS ODI workstation driver for NetWare v4.x is  *
     * referred to by Novell as the "DOS Requester" or the *
     * "DOS Client".                                       *
     *******************************************************

Before continuing, make sure you are not connected to the network, and that
no network drivers are loaded.  Then locate the Novell client for DOS and
Windows diskettes and the diskette containing TCTOK47.COM and TCTOK47.INS.

After you have located the diskettes, take the following steps:

1    Run the installation program from a DOS prompt.  (If the workstation
     runs Windows, exit Windows.)  Insert the first diskette into a 
     diskette drive, switch to the drive, and type INSTALL and <Enter>. 

2    Install presents you with a multi-step menu.  You can scroll
     through the menu steps by pressing the <Up> or <Down> arrow
     keys.  Press <Enter> to edit the information in a particular step.

3    Locate the option "Press <Enter> to install the driver for your
     network adapter".  This is the option that you will use to
     install the TC4047 driver; press <Enter> at the prompt.

4    The "Insert Driver Disk" menu should then prompt you to insert 
     a diskette.  If this menu does not appear, it means that Install
     detects a currently-loaded driver.  In that case, you should exit
     Install, completely unload all network drivers (including the shell,
     IPXODI, and LSL), then restart Install.

5    At the "Insert Driver Disk" menu, insert the diskette containing
     TCTOK47.COM and TCTOK47.INS in a diskette drive.  If the drive is 
     not Drive A:, type in the letter of the drive.  Press <Enter>.

6    Another menu then appears.  Select "Thomas-Conrad TC4047 adapter" from
     this menu by pressing <Enter>.

7    After you make this selection, the next menu displays driver 
     options.  To change the value of an option, move to it using the 
     <Up> and <Down> arrow keys and press <Enter>.  

     Additional help, along with the available selections for the selected
     option, appears on the screen.  A complete listing of all driver option
     with explanations appears in the next section, titled "Installation
     Procedure - Manual Installation".

8    When you are finished configuring the driver, press <Esc> and follow the
     prompts on your screen to complete the installation and exit Install.


Example Installation Files
------- ------------ -----

Install creates two files, named STARTNET.BAT (which loads the driver and
support files) and NET.CFG (which includes driver configuration 
parameters).  These files are located in the directory you selected with
Install (by default, C:\NWCLIENT). 

Sample files are shown below.  Yours might be different, depending
on the installation options you selected.  You can modify these
files using a text editor.

Sample STARTNET.BAT 
------ ------------

     SET NWLANGUAGE=ENGLISH
     C:\NWCLIENT\LSL
     :DRIVER1
     C:\NWCLIENT\TCTOK47.COM
     C:\NWCLIENT\IPXODI
     C:\NWCLIENT\VLM

Sample NET.CFG
------ -------

     Link Driver TCTOK47
          FRAME TOKEN-RING MSB
          MAX FRAME SIZE 16490

     NetWare DOS Requester
          FIRST NETWORK DRIVE = F
          NETWARE PROTOCOL = NDS BIND

The parameters under the statement "Link Driver TCTOK47" are configuration
options for TCTOK47.COM.  The statements shown above specify the TOKEN-RING
frame type ("MSB" means "Most Significant Bit"); set a maximum frame size for
transmits or receives of 16490 bytes (16KB).

The parameters under the statement "NetWare DOS Requester" are NetWare
configuration options.  Consult your NetWare documentation for more
information about these or other NetWare parameters.


=====================================
  INSTALLATION PROCEDURE (MANUAL  
  INSTALLATION)                   
=====================================

To manually configure the driver to connect to a network running NetWare
v4.x or v3.x, take the following steps:

1    Locate all of the files listed below:

     LSL.COM        The Novell Link Support Layer.

     IPXODI.COM     The Novell IPX protocol stack.  If you are using the IP
                    protocol stack (such as Novell's LAN Workplace for DOS),
                    you need to locate the diskettes containing the IP
                    protocol stack and support files.

     TCTOK47.COM    The TC4047 driver.

     (shell)        The shell intercepts DOS commands.  It can be any of the
                    following:  NETX.COM, NETX.EXE, or VLM.EXE.  If you are
                    using VLM.EXE as the shell, you will also need to locate
                    the .VLM files.  Consult your NetWare documentation for
                    more information.

2    Copy LSL.COM, IPXODI.COM, TCTOK47.COM and the shell to a local hard
     drive directory, or to the root directory of a boot diskette.

3    Create or edit a NET.CFG file.  NET.CFG is a text file
     that contains TCTOK47.COM configuration parameters and NetWare 
     configuration parameters.  The remainder of this section lists 
     TCTOK47.COM configuration parameters and shows supported values 
     for those parameters.  For more information about other parameters
     (such as NetWare parameters) that can be included in NET.CFG, 
     consult your Novell documentation.

     NET.CFG must reside in the same directory as LSL.COM and TCTOK47.COM. 
     You can use any text editor to create it, or you can use the COPY CON
     command as shown in Step 4.

4    To create NET.CFG from a DOS command prompt, first switch to the drive
     and directory containing LSL.COM and TCTOK47.COM and enter the following
     command:

     COPY CON NET.CFG

     Press <Enter> and follow the instructions in Steps 5 and 6 to create the
     file.  When you are finished, press either <Control>+<Z> or <F6> to save
     the file.

5    The first driver configuration statement is shown below:

     LINK DRIVER TCTOK47

     The statement shown above can appear anywhere in your NET.CFG file. 
     Place each driver configuration parameter on a separate line under 
     "LINK DRIVER TCTOK47" and indent each with a single space or tab
     character.  Parameters are shown in Step 6.  Sample NET.CFG files
     follow.

6    A listing of all parameters and options for each is shown below:

     SLOT [value]

          Supported Values:  1 - 16
          Default:  n/a
          The driver automatically locates the slot containing a TC4047.
          This parameter is required if more than one TC4047 is installed 
          in the machine; it specifies the slot number in which the TC4047 
          is installed.

     MAX FRAME SIZE [value]

          Supported Values:  2168, 4216, 8312, 16490
          Default:  4216

          Specifies the largest frame size, in bytes, that the adapter can
          transmit or receive.  The default, 4216, is equivalent to a 4KB
          maximum frame size.  This is the largest frame size allowable on
          4Mbps networks.

          Entering a value not in the list above means the driver will use
          the next-largest frame size as its maximum.  For example, entering
          "MAX FRAME SIZE 5000" will result in the driver using a maximum
          frame size of 8312 (8KB).

     FRAME [value]

          Supported Values:  TOKEN-RING, TOKEN-RING_SNAP
          Default:  TOKEN-RING

          Selects the type of frame to use.  To use both frame types, enter
          the parameter twice, as shown below:

          FRAME TYPE TOKEN-RING
          FRAME TYPE TOKEN-RING_SNAP

     NODE ADDRESS [value]

          Supported Values:  Any unique hexadecimal value between
          400000000000h and 40007FFFFFFFh.
          Default:  n/a

          This parameter, also called a "locally-administered node ID",
          overrides the adapter's burned-in node ID (printed on a label on
          the adapter Node ID ROM).  The locally-administered node ID must
          be unique on the network.

     REINSERT

          Supported Values: n/a
          Default:  absent

          Using this parameter means that the driver will automatically
          reinsert into the ring after receiving a MAC "Remove" frame.  Some
          network management programs, such as Sectra Token Ring Manager,
          allow "Remove" frames to be issued in certain conditions (such as
          error conditions).  Using this keyword effectively prevents
          management software from removing the workstation from the ring. 
          The default, with no keyword specified, is for your computer to be
          removed from the network after the driver receives a MAC "Remove"
          frame.

     DETR

          Supported Values: n/a
          Default:  absent

          Disables the early token release feature for 16Mbps networks.  Has
          no effect on 4Mbps networks.  

     NON_VDS
          Supported Values: n/a
          Default:  absent

          This parameter can be used if the workstation is using a memory
          manager that does not conform to Virtual DMA Services (VDS).  This
          parameter is not normally needed but can be used if you are having
          problems using the driver with an older memory manager, for
          example.

7    Save your changes to NET.CFG and return to a DOS command prompt.  

8    If you are using the IP protocol, consult the protocol vendor's
     documentation for instructions on installing and using it.

9    Load the network drivers by entering the commands in the order shown
     below:

     LSL
     TCTOK47
     IPXODI
     (shell)


Sample NET.CFG Files
------ ------- -----

The samples shown below are partial NET.CFG files, because they show only
TCTOK47.COM configuration parameters.  Remember that your NET.CFG file 
can contain additional NetWare configuration statements not shown in the
samples below.

Sample #1:  Sets a maximum frame size of 16490 bytes (16KB):

     LINK DRIVER TCTOK47
          MAX FRAME SIZE 16490

Sample #2:  Sets a locally-administered Node ID, and disables the Early Token
Release feature:

     LINK DRIVER TCTOK47
          NODE ADDRESS 400023456789
          DETR

Sample #3:  Allows the adapter to reinsert into the ring after receiving a
MAC "Remove" frame:

     LINK DRIVER TCTOK47
          REINSERT
