LNE390 EISA Ethernd IAN Adapter Introduction
Chapter 1: -Introduction
Basic Description
The Mylex LNE390 series Ethernet Adapters provide a high
performance, cost-effective interface for EISA host systems to
any IEEE 802.3 compliant Local Area Network. There are two
products in the LNE390 series.
LNE39OA

June 1992 lOBad (“Thick” Ethernet) or
lOBaee2 (“Thin’ Ethernet) or
1OBaseT CTwisted Pair)
The LNE3908 incorporates all the features of the LNE39OA,
and adds support for Ethernet twisted pair (1 OBaseT).
Other features of the LNE series include:
32-bii EISA bus interface
32KB shared SRAM memory
National Semiconductor DP8390 Network Inter-
face Controller
Fully programmable settings -- no switch set-
tings or option jumpers on-board
Supports up to 4 LNE390 units in the same host
system

LNE390 EISA Etherno IAN Adapter
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).

2. 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 ls
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 of This Document
The manual assumes the reader is familiar wlth normal ISA
and EISA style computer operating procedures, and is 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
An LNE390 may be installed in any available EISA
I/O slot in a host system. The bask steps for
hardware installation are:
1. Install the adapter hardware in the system.
2. Connect the adapters to the LAN.
3. 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, tt
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.
