Introduction

Novell Certified Support for Novell Netware as

both server and workstation

SC0 UNIX Driver

ISC UNIX Driver

NDIS

Driver for OS/2 and DOS

Theory of Operation

The

LNE390

may be added to any

EISA

host system in any

availaMe

EISA

I/O

slot. One of the connectors on the back of

the unit is connected to an 802.3 compatible Local Area Net-

work. The LNE390 acts as a complete interface between the

software running of the host system and any other node on the

LAN. Figure l-1 shows a basic block diagram of the

LNE390.

The LNE390 off-loads most of the low-level LAN management

functions from the host system. These functions are per-

formed by the National Semiconductor

DP8390

NIC chip,

which runs under control of the software in the host system.

Each operating system supported by the

LNE390

is provided

with

a special driver which provides a software interface be-

tween the operating system and the LNE390. In the case of

DOS, the driver is loaded as a TSR (Terminate and Stay

Resident) program which is combined with a ‘Network Shell

that provides network services to the DOS user.

For Novell

Netware 3.1 x, the driver is loaded with a LOAD command after

the server system has been started. UNIX systems (both

SC0

and

ISC)

require the driver to be linked into the operating

system kernel before network services can be used.

The resources of the

EISA

host system used by the

LNE390

are:

1. A uniquely assigned Interrupt Request Line

(IRQ).

1992

LNE3SO

EEA

Ethwnot

LAN

Adaptor

Sixteen bytes in

I/O

address space (EISA

slot

specific)

3. 64KB in memory address space, non-cached.

(Note that although the LNE390 provides

32KB of shared SRAM, 64KB memory

addresses are used by each board.)

The software driver communicates to the

LNE396

by loading

and storing data packets to and from the 32KB shared mem-

ory. The management and allocation of the shared memory

under the control of the host program.

In the case of a transmission, the

driver

then uses

I/O

instruc-

tions to instruct the

DP8396

to send the data packet. The

DP8390

then runs

asynchronousfy

and will attempt to transmit

the packet up to 16 times. Upon completion or error, the

LNE390 then

lntem~pts

the host processor,

which

can then

read status

bits,

and then handle the resulting condition,

For data reception, the software driver programs the

DP8399,

indicating the appropriate buffer memory addresses for data

packet reception. When a data packet is received, the

’

LNE390

interrupts the host, and can then respond to the

received data packet.

Scope

This Document

The manual assumes the reader is familiar wlth normal ISA

and

EISA

style computer operating procedures, and

familiar

with the particular operating systems to be used. The proce-

dures detailed will enable the user to install the

LNE399

In any

EISA

host system with any of the supported operating sys-

tems.

Chapter 2: Hardware Installation and

Configuration

Overvlew

LNE390

may be installed in any available

EISA

I/O

slot in a host system. The bask steps for

hardware installation are:

Install the adapter hardware in the system.

Connect the adapters to the

LAN.

Configure the

LNE390

using the host system’s

EISA

Configuration Utility.

This chapter

covers

these procedures.

To use the

LNE390

after the hardware Is in place,

will be necessary to install the host operating sys-

tem and the appropriate

device

driver. For operat-

ing system installation, refer to the

documentation

that comes with the operating system software.

The installation of

LNE390

device

drivers is cov-

ered by subsequent chapters in this manual.

LAN

Media

Configuration for the

LNE39OA

Before the

LNE39OA

can be installed In a system,

it must be

configured

for the type of LAN you are

using. This is done by changing the settings of a

jumper block on the board, as shown in Fugure 2-1.

This operation is now required for the

LNE390B.

When the board is in place, the notch in

the

top of

the bracket should line up with the screw hole for

the mounting screw.

If it does not, check the

atign-

ment of the

LNE390

and the depth of the connector

insertion.

Complete the board installatbn by replacing the

mounting screw.

Replace the system cover as per

the manufacturer’s instructions.

As a

flnal

step, the LNE390 must be connected to

the network media.

For

1OBase

5, the 15 pin D-connector Is used to

connect a standard Ethernet transceiver unit to the

LNE390.

For 1

OBase

2, the BNC connector is used to attach

a BNC

‘T’

connector to the

LNE390.

The other two

poles on the

‘r

connector are attached to coaxial

cables which make up a Thin Ethernet lAN.

For

1OBaseT

(LNE39OB

onfy),

the

RJ45

modular

plug is used to connect the

LNE390

to a network

hub.

If the LNE390 is to be connected directly to

another

1OBaseT

Ethernet Adapter (such as an-

other

LNE39OB),

a special

cabte

that reverses the

signals is required.

Note:

During the

configuration

procedure, it is

advisable to

make a manual note of the configura-

tion

options selected. This information will be re-

quired during the installation of various operating

system drivers described in the following chapters.

In order to perform this function, the

EISA

Configu-

ration Utility refers to a special data base file that

describes the

LNE390

and the possible options it

supports. This data base file (different for

LNE390A

and

LNE390B)

is contained on the

LNE390 Driver Diskettes

(DOS

format).

Refer to the host system’s documentation for in-

structions on how to start the

EISA

Configuration

Utility. These instructions also have instructions on

how to copy the configuration data base files to the

floppy diskette on which they will be used. As a

shortcut, however, it is possible to place the

LNE390

Driver Diskette in Drive B, and the

EISA

Configuration Utility diskette in

Drtve

A, and enter

the following DOS command:

COPY

B:\*.CFG

This will place all the available files on the Configu-

ration Utility Diskette, which will make them avail-

able for use when the program is run.

When the

LNE390

board(s) are recognized ‘by the

EGA

Configuration Utility, a configuration screen is

displayed. To configure the

LNE390

is a software driver

(LNE31.tAN)

for Novell NetWare

V3.xx

(also re-

ferred to as NetWare 386). In addition, the

LNE390

provides

both IPX

ODI

(LNE.COM)

workstation

drivers for

DOS.

These software modules are

found on the

LNE390

Driver Diskette

(DOS

This chapter provides the procedures for using

these drivers. It is assumed that the reader is

familiar

wtth

installing the Novell NetWare system

and has already done so.

NetWare 3.11 Server

Driver

The LNE390 NetWare Driver is the file named

LNE31LAN

on the

LNE390

Driver Diskette root

directory. To use this driver it is necessary to copy

this file to the DOS Disk Directory from which Net-

Ware is started. If the installation starts NetWare

from a diskette, the LNE31 .lAN file should be cop-

ied to that diskette.

SERVER

In order for the

LNE399

driver(s) to become

active

and usable by the NetWare server, it is necessary

for the server to execute a ‘LOAD’ command.

There will be one LOAD command for each

LNE390

operating on a unique frame type, being

supported by the network. In addition, each board

installed in the system will require one BIND com-

mand to tie a NetWare

senrice

into the

speciftc

For a more complete description of the

NetWare documentation.

LOAD and BIND commands are normally

located within the AUTOEXEC.NCF file that

the NetWare server executes each time it IS

started. This file may be edited from within the

server by executing the INSTALL program

provided with NetWare (started with a LOAD

INSTALL) command.

Alternatively. the LOAD and BIND commands

may also be typed in at the “dot prompt”, as a

manual command This method is normally

used in experimental servers where the

configuration changes frequently, or when

IPX

network interface program. The IPX program

is created by the user by combining an

file provided with the

LNE390

board with me

skeleton IPX file provided by Novell. The

combining process is performed by the Novell

supplied

WSC3EN

program.

WGEN

also modifies the
