Description:   DOS NDIS 2.01 Driver for Racal-Datacom InterLan AT
Version:       3.01
Release Date:  January 1993
Part Number:   158-0330-00
	       149-0330-00


SECTION 1 - Overview
--------------------
The driver in this directory allows the Racal-Datacom InterLan AT to be 
used in DOS-based systems to run networking software written to the NDIS
specification. 

This driver has been written for conformance to the NDIS specification as 
described in "Microsoft/3COM LAN Manager Network Driver Interface 
Specification - Version 2.0.1". 

Version 3.01 has been tested for correct operation with Microsoft Lan Manager 
2.1 and Windows for Workgroups 3.1.  It has passed Microsoft Conformance Tests 
conducted in the Racal-Datacom labs using test tools provided by Microsoft.

Note that the explanations in Section 4 and Section 5 generally apply to 
LAN Manager systems. They may or may not apply to other protocol stacks
that use NDIS drivers. Complete details can be found by referencing the
driver section of your network software documentation.


SECTION 2 - Contents of this directory
--------------------------------------
To help you install and use this product, the following files are included in
this directory:

RELEASE.TXT  - This file

SAMPLES.TXT  - Sample configuration files for commonly used NDIS-based
	       protocol stacks

ILANAT.DOS   - InterLan AT DOS NDIS Driver

PROTOCOL.INI - Text file that describes the configuration of the driver 
	       and data-link card to the networking software.

	       You may have to edit this file to match the physical 
	       configuration of your card. For more information, see
	       Section 4 for an explanation of the PROTOCOL.INI parameters.

The ILANAT.DOS and PROTOCOL.INI files are included in the \MSLANMAN.DOS
directory on this diskette in the structure recommmended by Microsoft to
allow automatic installation under LAN Manager.

Also included under \MSLANMAN.DOS is the ILANAT.NIF file, which is used
by the LAN Manager setup program to display available network drivers. See
Section 4 for an explanation of the ILANAT.NIF parameters.



SECTION 3 - Installing NDIS drivers under LAN Manager 2.1
---------------------------------------------------------
To install a network driver under LAN Manager, we recommend that you import 
the driver using the SETUP program, as follows:

1) Move to the LANMAN installation directory (typically C:\LANMAN.DOS) and 
   invoke SETUP. 

2) Select the CONFIGURATION menu and choose the NETWORK DRIVERS option.
   Select the ADD NEW CONFIG option.  (Any existing configuration can be
   deleted with REMOVE CONFIG).  Select OTHER DRIVER and follow the 
   instructions for importing the driver from a floppy diskette.

3) Once the driver has been imported, select the appropriate protocol stack
   (or stacks) to bind to the driver.  (The ILANAT driver does not currently 
   support more than one InterLan AT card in your system.)

SETUP should make the necessary driver modifications to the CONFIG.SYS and
PROTOCOL.INI files.  Consult the Lan Manager manual for more information.

For example, if you configured the NetBEUI protocol stack to bind with the 
InterLan AT card, the resulting PROTOCOL.INI file should contain the following:

  [NETBEUI_XIF]
    DRIVERNAME = NETBEUI$
    .
    .
    BINDINGS   = "ILANAT_NIF"

  [ILANAT_NIF]
    DRIVERNAME    = ILANAT$
    IOBASE        = 0x300
    .
    .

You must ensure that the IOBASE setting in PROTOCOL.INI matches the 
hardware setting on your InterLan AT card.

The ILANAT driver will appear in CONFIG.SYS as follows:

   DEVICE=C:\LANMAN.DOS\DRIVERS\ETHERNET\ILANAT\ILANAT.DOS 



SECTION 4 - Entries in the PROTOCOL.INI File
--------------------------------------------
The following tables summarize possible entries and values in the 
[ILANAT_NIF] section of the PROTOCOL.INI file:

	   TABLE 1 - Description of Entries in PROTOCOL.INI
----------------------------------------------------------------------
Entry                           Explanation
----------------------------------------------------------------------
DRIVERNAME     Identifies the network device driver. DRIVERNAME is the
	       base portion of the file name, plus a digit if more than
	       one InterLan AT is installed. DRIVERNAME is ILANAT$ for
	       the first InterLan AT, ILANAT2$ for the second, and so on.

----------------------------------------------------------------------
IOBASE         Indicates the base I/O address for the NIC. If this
	       entry does not match the NIC's I/O address jumper
	       settings, the driver reports an error. If this entry is
	       omitted, the driver looks for the first available NIC.
----------------------------------------------------------------------
MAXMULTICASTS  Sets the maximum number of multicast addresses the
	       driver supports.
----------------------------------------------------------------------
MAXRECEIVES    Sets the number of receives that can be queued
	       simultaneously. 
----------------------------------------------------------------------
MAXTRANSMITS   Sets the number of TransmitChain commands that can be 
	       queued simultaneously.
----------------------------------------------------------------------


These entries can have the following minimum and maximum values: 

      TABLE 2 - Min/Max Values for PROTOCOL.INI Entries
-------------------------------------------------------------------        
Entry           Minimum         Maximum         Default
-------------------------------------------------------------------       
DRIVERNAME      ILANAT$           -             required entry
-------------------------------------------------------------------
IOBASE          0x300           0x380           0x300
-------------------------------------------------------------------
MAXMULTICASTS   1               16              10
-------------------------------------------------------------------
MAXRECEIVES     1               6               3
-------------------------------------------------------------------
MAXTRANSMITS    1               50              6
-------------------------------------------------------------------




SECTION 5 - Entries in the *.NIF File
-------------------------------------
The following table summarizes possible entries in the *.NIF file:

		  TABLE 3 - Entries in the *.NIF File
----------------------------------------------------------------------
Model          Used by the LAN Manager SETUP program to display the
	       name of the driver.
----------------------------------------------------------------------
Path           Directory location of all files pertinent to the 
	       driver, i.e. PROTOCOL.INI and the driver itself
	       (ILANAT.DOS or ILANAT.OS2). The LAN Manager
	       installation program appends the value of this field 
	       to "@lanroot\drivers\" to create a complete path for
	       accessing PROTOCOL.INI and the device driver. Check the
	       value of "@lanroot\drivers" (or equivalent field for
	       other network operating systems) if your installation
	       program cannot find the driver or PROTOCOL.INI files.
----------------------------------------------------------------------
DeviceDriver   Name of the driver that will be added to CONFIG.SYS.
	       If more than one driver must be added, then multiple
	       "DeviceDriver" lines should be specfied.
----------------------------------------------------------------------
Type           Specifies that the driver is an NDIS driver
----------------------------------------------------------------------
Xports         Applies to NDIS drivers only and indicates the
	       transports that this driver has been tested with. A
	       warning may be generated by the LAN Manager SETUP
	       program if the user attempts to combine the driver with
	       a transport that is not listed in the Xports list.
