Introduct ion

Thank you for choosing D-Link DFE-650, the value leader among
PC-Card Fast Ethernet adapters. This chapter provides a general
description of DFE-650 Series features, with a summary of features
at the end of the chapter. Installation instructions are given in
Chapter 2.

General Description

The D-Link DFE-650 Series Fast Ethe rnet PC Card is a cre dit-card
sized Fast-Ethernet adapter for connecting a notebook PC to an
IEEE 802.3 or 802.3u Ethernet network. The notebook PC must be
equipped with a T ype II or T ype III PC Card slot.

NOTE:

The terms "PC Card" and "PC Card slot" are used

throughout t his manual to refer t o those objects as defined
in the Personal Computer Memory Card Industry Associa­tion (PCMCIA) standards.

The DFE-650 automatically detects the parameters of its Ethernet
environment, and automatically negotiates and determines its own
speed and duplex settings as required for maximum performance in
its environment.

Inside its compact PC-Card package, the D-Link DFE-650 holds an
Ethernet controller, network processing interface, 64 Kb RAM data
buffer, a 68-pin PC Card Standard front-end plug which connects to
the notebook PC, and a 15-pin back-end receptacle for connecting

Introduction

the media coupler. The DFE-650 requires no pre-installation setup

––

simply insert it s front end i nt o the not ebook PC' s PC-Card slot.

The DFE-650 is supplied with a media coupler which plugs into the
back end (15-pin receptacle) of the DFE-650. The other end of the
media coupler has an RJ-45 receptacle which receives the network
cable. The media coupler features LED indications for linkage and
activity states, and for the speed and duplex settings.

About Fast Ethernet

Fast Ethernet is a network technology specified by IEEE Standard

802.3u. It extends the traditional 10Mbps (10 megabit/sec)
Ethernet technology to achieve 100Mbps (100 megabit/sec)
transmission and reception. Because Fast Ethernet retains the
traditional Ethernet CSMA/CD (Carrier Sense, Multiple Access,
Collision Detect) protocol, it remains wholly compatible with
10Mbps Ethernet while providing a tenfold increase in network
capacity.

The Fast Ethernet standard specifies three subtypes, corresponding
to three media types:

100Base-TX (using two twisted pairs in EIA 568 Category 5
UTP or ST P c a b l e)

100Base-T4 (using four twisted pairs in a Category 3,
Category 4, or Category 5 UTP cable)

100Base-FX (using two fiber-optic strands).

D-Link DFE-650 Series Fast Ethernet PC Cards offer half-duplex
100Base-TX operation (in Category 5 twisted-pair cable
environments). These products do not support 100Base-T4 or
100Base-FX operation. To provide for traditional 10Mbps Ethernet
operation in twisted-pair cable environments, the DFE-650 series

also offers 10Mbps Ethernet operation, in full-duplex and half­duplex modes. Selection of the best operation mode in any given
installation is automatically governed by autonegotiation.

About Autonegotiation

The basic idea of autonegotiation can be understood by reflecting
for a moment on the familiar process of making a dialup connection
between two modems. You have probably heard some
gravelly−sounding exchanges between your local modem and a
modem at the other end of a telephone line. (These exchanges are
ordinarily played out through a speaker in your local modem). As
irritating as those few seconds of noise may be, they do let you
know that your modem and the remote modem are on the job,
preparing for your intended communication with the remote
computer.

The preparat ory work of the two modems during those few seconds
before you see the “connect” message is to

negotiate

the best data
communication scheme which is supported by both modems, and
which is suitable for the quality of the telephone-line connection
between them. The parameters to be settled between the two
modems include best baud rate, compression method, and error
correction method. When the two modems have tested the phone­line quality and have switched to the combination of parameters
which will provide the best data communication, then you are given
the “ connect” message which signals the end of the inter-modem
negotiation and the beginning of your intended communication with
the remote computer.

Autonegotiation between devices within an Ethernet LAN is similar
in concept, but much briefer. The two devices involved in the
autonegotiation will be your DFE-650 Series PC Card and the hub
or switch through which it is connected into the LAN. (Switches
ordinarily provide autonegotiation functionality; hubs usually do

DFE-650 Series Fast Ethernet PC Card User's Guide

Introduction

not.) The parameters to be negotiated between the DFE-650 and its
supporting hub or switch include speed (100Mbps = Fast Ethernet,
or 10Mbps = traditional Ethernet) and dupl ex mode (half-duplex or
full-duplex).

Startup communication between the two devices occurs when both
devices are operating, the cable connection between them is good,
and the connected notebook PC's network software is loaded. As
soon as those conditions are satisfied, the preparatory process of
autonegotiation between the DFE-650 and its supporting device
begins and proceeds automatically.

If the supporting hub or switch has autonegotiation functionality,
then it and the DFE-650 exchange a series of messages in which
each device signals its capabilities and listens for corresponding
information about the other. The autonegotiation process requires
only a few milliseconds, and the two devices select the best
communication parameters supported by both devices.

If the supporting device does not have autonegotiation
functionality, then its monotone (single capability) message will be
recognized by the DFE-650’s autonegotiation facility, and the DFE­650 will simply switch to the one of its own capabilities which
matches that of the supporting device.

Once the autonegotiation is completed, then the line is ready, and it
will provide an optimal data channel between the DFE-650 and the
supporting device. The line will remain ready without further
autonegotiation action until the linkage is broken. Autonegotiation
then reoccurs at any time that the linkage is restored, again making
the line ready for optimal data communications.

LED Indicators

The media coupler features three LED indicators:

1. 10/100 Indicator

Steady green indicates Fast Ethernet selected.
Dark indicates 10Mbps Ethernet selected.

2. Half /Full Indicator

Steady green indicates Full-Duplex selected.
Dark indicates Half-Duplex selected.

3. Ln/Act Indicator

Steady green indicates that there is good linkage to the network
("Linkage" state, quiescent).

Flashing green indicates that the DFE-650 is transmitting or
receiving ("Activity" state). In 10Mbps mode, flashing will be
regular and periodic. In 100Mbps mode, flashing may be
irregular, with longer dark periods during heavy traffic activity.

In the event that any item is missing, or if you find any mismatch or
damage, promptly contact your dealer for correction.

Hardware Installation

Follow these four steps to install the DFE-650 :

Step 1 Insert th e DFE-650

Under the PCMCIA standard and the corresponding Japanese
JEIDA standard, PC Cards may safely be "hot swapped" –– it is not
necessary to switch the computer's power off before installing or
removing the DFE-650, or a ny ot her PC Card.

Find/select an open Type II or Type III PC Card slot on your
notebook compute r' s side or rea r pa nel . Hold the DFE-650 with t he
colorful D-Link splash label upward. Notice that the splash label
features a yellow triangle or "arrow," which points to the front end
of the PC Card. Insert the front end of the PC Card into the PC
Card slot, and slide the PC Card all the way into the slot until it
reaches a firm stop.

Hardware Installation

It is most usual for the lower one of the two slots in the
stack to be designated Slot 1, but there are except ions. In
the subsequent procedure for DFE-650 software
installation, it may be necessary for you to know whether
your DFE-650 is installed in Slot 1 or Slot 2. Under
Windows 95, you can check by opening the Control Panel /
PC Card display. Under DOS it is also possible to make a
softwar e check, but it is more dif ficult. If you are unable to
determine the DFE-650's slot number in advance, then you
can make a trial-and-error determination later, according t o
instructions given in the Softwar e Installation section of this
chapter.

Step 2 Attach the Media Coupler

The back-end receptacle of the DFE-650 remains accessible
(approximately flush with the case of the computer) when the DFE­650 is properly seated in its PC Card slot. Taking care to keep the
top side of the media coupler plug up, insert the plug into the DFE­650's receptacle until it is firmly seated and latched. (The top side
of the plug is labeled with a triangle molded into the plastic.)

Keep the tri angle ma rk on
top when you plug the media
coupler into the DFE-650

NOTE:

When the media coupler plug is firmly seated, it is held in

place by small latching hooks at either side of the plug. To

avoid damage when detaching the plug from the DFE-650, it
is necessary to depress the latch wings of the plug. See
the following section, "Remove Ethernet PC Card. "

Step 3 Connect to the Network Medium

Make the network connection by running a UTP cable from the
supporting hub to your media coupler. Simpl y plug one end (RJ-45
connector) of the cable into an available hub port, and plug the
other end (RJ-45 connector) into the RJ-45 socket of the media
coupler.

Step 4 Confirm Connection (Ln/Act Indicator)

When the notebook computer's power is ON, the DFE-650 is firmly
seated in the slot connector, the media adapter plug is firmly
engaged (and latched) in the back-end receptacle of the DFE-650,
the media adapter has a good cable connection to the supporting
hub, and the supporting hub is power on and functioning properly,
then the media coupler’s Ln/Act LED glows steady green
("linkage" state).

If the Ln/Act LED remains dark without apparent cause, then the
most likely fault is poor engagement of the 68-pin front-end plug.
Review the following section titled "Remove the DFE-650," then
remove the DFE-650 from its slot. Repeat the procedures of the
above Step 1, "Insert the DFE-650," taking care to ensure that the
DFE-650 is right side up and front-end first, and that it seats firmly
in a suitable PC Card slot of your notebook. Repeat procedures of
Steps 2 and 3 as necessary get the Ln/Act LED confirmation.

NOTE:

You might need to wait a few seconds following notebook
powerup, or following insertion of a PC Card, for the
softwar e processing to be complet ed. The Ln/Act indicat or
w ill rema in dark until th e s oftwar e p ro ce ss ing is c ompleted.

Remove the PC Card

Follow these two steps to remove the DFE-650 it s slot:

Step 1 Disconnect the Media Coupler Plug from the DFE-650

Unplug the media coupler from the DFE-650 before ejecting the
DFE-650 from the PC Card slot. The media coupler plug i s held in
place by small latching hooks at either side of the plug. To remove
the media coupler plug from the DFE-650, it is necessary to unlatch
the hooks by depressing the two small latch wings of the plug. Use

thumb and forefinger to squeeze the latch wings into the plug body
and gently pull the plug out of its receptacle.

Don't pull the connector without depressing the clip wings

WARNING:

Pulling the coupler plug out of its receptacle without
depressing the clip wings will ca us e damage t o t he plug.

Hardware Installation

Step 2 Eject the DF E - 650 f rom the Computer

Firmly press the computer's PC Card Eject button to disengage the
DFE-650 from the slot connector. The DFE-650 will then protrude
from the PC Ca rd slot. Grip its protruding end be tween your finge rs
and withdraw it from t he PC Card slot .

Connect the Network Cable

Category 5 UTP cable is good enough to qualify under both the
Fast Ethernet cabling rules and the traditional Ethernet cabling
rules. The maximum individual cable run between any station and
its supporting hub or switch is 100m. The maximum individual
cable run joining two hubs is 10m in general, but is 100m when
both hubs qualify as Ethernet Class 2 Repeaters (

all

D-Link
Ethernet hubs do qualify). But these cable runs may need to be
shorter than the given individual maximum lengths, because their
lengths are also restricted by the rule that the maximum

aggregated

cable run between any two stations is 205m.

Connecting for Fast Ethernet

Category 5 UTP cable is required for Fast Ethernet operation. The
maximum cable run between the DFE-650 and the supporting hub
is 300 ft. The ca ble must be “stra ight” (not a “crossover” c able),
with an RJ-45 plug at each end. Make the network connection by
plugging one end of the cable into the RJ-45 receptacle of the
media coupl er, a nd t he ot he r end i nt o a port of t he supporti ng hub.

Connecting for 10Mbps Ethernet

Category 3, Category 4, and Category 5 UTP cable, as well as
EIA/TIA - 568 100-ohm STP cable, all qualify under traditional
Ethernet c abling rules. The maxi mum cable run between t he DFE-

650 and the supporting hub is 300 ft. The ca ble must be “ straight ”
(not a “ crossover” cable) with RJ-45 plug at each end. Make the
network connection by plugging one end of the cable into the RJ-45
receptacle of the DFE-650, and the other end into a port of the
supporting hub.

Software Installation

Hardware installation as described in Chapter 2 must be completed
before you proceed with software installation.

Instructions for software installation are given as README files on
the D-Link DFE-650 Series Fast Ethernet PC Card Driver diskette.
The diskette also holds the Installation Director program, which
helps you access the installation instructions appropriate to your
station OS and the network environment.

Run Installation Director

For proper function of Installation Director, it is necessary that the
DFE-650 to be plugged into a PC Card slot of the notebook PC.
Ascertain that the DFE-650 is in place, according to Step 1 of
Hardware Installation, Chapter 1, then insert the D-Link DFE-650
Series Fast Ethernet PC Card Driver diskette into the diskette drive
of the notebook PC. Then select that drive as the active drive. In
the Run dialog box, or at the command prompt, type the letter
designator for that drive (here assumed to be A), and complete the
line as follows:

A:\install.exe

Then key

<Enter>

to run Installation Director. It will guide you
to, and display, the appropriate installation instructions.
Installation Director provides installation instructions for every
combinati on of platform OS and net work environment in which the
DFE-650 can be used.

DFE-650 Series Fast Ethernet PC Card User's Guide

Software Installation

17

During your Installation Director run, if you choose DOS as your
station OS, then in some cases Installation Director will provide
additional services. In such cases, you will be prompted to select a
target directory for storage of software modules that Installation
Director will copy over from the D-Link DFE-650 Series Fast
Ethernet PC Card Driver diskette. The README t ext will provide
full information on the additional services provided..

Installation Director also provides access to the Diagnostic
Program, which may be used to che ck the hardware com ponents of
the DFE-650, as well as its proper interoperation with your
network.

For the case that you have a Novell NetWare network environment
and your notebook PC workstation is running MS-DOS (or
equivalent) or Windows 3.1, then Installation Director will lead you
to the appropriate installation README, and you will also find
expanded installation instructions in the following subsections of
this chapter. Refer to whichever instructions you find most
comfortable.

Expanded Installation Instructions:
DOS Platform in NetWare Network

If your notebook PC is running MS-DOS or an equivalent OS, then
you have a choice between two flavors of NetWare client software.
You can choose to install the traditional 16-bit NetWare Client for
DOS, or you can install the 32-bit NetWare Client32 for DOS.
Both types of client software will provide excellent service. It is
not certain whether there is a performance benefit in using the 32­bit client software under DOS. But the proce dure for installation of
the 32-bit client software is by far more complicated. Thus you
might choose to make an overview comparison of the following
installation instructions for the two kinds of client software before
you decide which to install.

DFE-650 Series Fast Ethernet PC Card User's Guide

Software Installation

Installing 16-bit NetWare Cli ent for DO S

Installation Director includes a Quick Install option for the DFE­650 support software required for interoperation with the 16-bit
NetWare Client for DOS. The screen text, status line guide text,
and helptext of Installation Director will assist you through the
Quick Install procedure.

Installing NetWare Client32 fo r DOS

Installation of the 32-bit support software for the DFE-650 can only
be accomplished as part of a new installation, or a re-installation of
the Client32 software on your notebook PC workstation. The
NetWare Client32 software includes a DOS-based installer
program, INSTALL.EXE, which is used for the original
installation, and for any necessary re-installation, of the Client32
software on your station. Thus INSTALL.EXE is also the
installation program for the DFE-650 support software required for
interoperation with NetWare Client32 for DOS.

Before you can proceed with any of the steps which follow, it will
be necessary for you to find a source for the NetWare Client32
software. Depending on decisions which have been made by the

C:\NOVELL\CLIENT32\> EDIT STARTNET.BAT

For each enabled frame type (four types at maximum),
STARTNET.BAT will include a line similar to this shortened
example:

LOAD C:\...\DFE650.LAN FRAME=...

Edit each such statement (there will be a maximum of four) as
follows: just ahead of the FRAME keyword, insert "

If you are uncertain whether the DFE-650 occupies Slot 1 or Slot 2,
and you have ente red the wrong slot numbe r, then when you resta rt
the notebook PC, there will be a diagnostic which advises that "the
PC Card is not present" and there will be no network connection. If
you do not get a network connection upon your restart, then rework
your editing of STARTNET.BAT, entering the alternate PC Card
Slot Number (substitute SLOT=2 in each place where you have
added SLOT=1).

Restart the notebook PC. Excepting the possibility that the wrong
PC Card Slot Number is indicated in STARTNET.BAT, you should
get a NetWare login upon this restart.

Expanded Installation Instructions:
Windows 3.1 Platform in NetWare Network

If your notebook PC station is running Windows 3.1, then you need
to install Client32 for DOS. (Fundamentally, the DFE-650 support
software modules to be installed are the same under Windows 3.1
and DOS. But the Windows 3.1-based installer program
SETUP.EXE does produce a different result from the installation
made by the DOS-based installer, INSTALL.EXE.)

Installing NetWare Client32 fo r DOS (under Windows 3.1)

Installation of the support software for the DFE-650 can only be
accomplished as part of a new installation, or a re-installation of the
Client32 software on your notebook PC. The NetWare Client32
software includes a Windows-based installer program, SETUP.EXE
which is used for the original installation, and for any necessary re­installation, of NetWare Client32 for DOS on your station.. Thus

DFE-650 Series Fast Ethernet PC Card User's Guide

24

Software Installation

the NetWare SETUP.EXE program is also the installation program
for the DFE-650 software.

Before you can proceed with any of the steps which follow, it will
be necessary for you to have a source for the NetWare client
software. Depending on decisions which have been made by the
NetWare administrator for your LAN, the NetWare client softwa re
may be available from a NetWare server on the LAN, or it may be
necessary for you to install from the Novell NetWare CD-ROM or
diskettes. If you are in doubt as to the proper source for your
NetWare client software, then please consult your NetWare
administrator.

Irrespective which form your source takes, you will need to identify
the directory which holds the NetWare Client32 for DOS softwa re.
If your source for NetWare Client32 for DOS is the NetWare 4.11
CD-ROM, then the appropriate directory will be (assuming that the
CD-ROM drive is E:),

E:\PRODUCTS\DOSWIN32\IBM_6

In Program Manager, choose RUN under the FILE menu, then, in
the RUN dialog box, choose the

Browse

button. Select the drive
which holds the software source, then navigate to the appropriate
directory. Double-click SETUP.EXE to initiate the installation run.

The initial screen in the SETUP.EXE run is only for the purpose of
selecting the language in which the screen instructions which will
appear during the rest of the SETUP.EXE run. Choose the

OK

button for English, or select another one of the languages offered,
and then choose the

OK

button. The NetWare Client 32 Welcome

your best choice to go ahead with the installation run by choosing
the Continue button. If the installation run is not successful, then
the information given in the README file might be more useful at
this stage in a second attempt.

When you choose the

Continue

button, the Software License
Agreement screen appears. Accept the provisions of the Software
License Agreement, and continue the installation run, by choosing
the

Yes

button. The Directory Locations screen appears.

Directory Locations Dialog

It is ordinarily suitable to approve the default entries which appear
in this dialog's two text boxes, by simply choosing the

Next>

button.
The first textbox provides for selection of a target directory to

receive your computer's copies of the necessary Client 32 files.
The textbox shows a default directory name which is ordinarily a
suitable choice. There is a "browse" button at the right of the
textbox. In all events, it is a good idea to write down the name of
this target directory, because you will need to know the directory
name at a later stage of the installation procedure.

The second textbox in this screen shows the name of the directory
which holds the currently active WIN.COM file. The textbox
provides for entry of a Windows filename different from the
currently active Windows directory. Do not change this textbox
unless you are doing a special procedure involving multiple copies
of the Windows 3.1 system software on your computer.

When you choose

Proceed as follows:

1. Exit Installation Director. Examine the CONFIG.SYS file in
the root directory of your notebook PC's startup drive (hard
drive). Ascertain that CONFIG.SYS contains a DEVICE
statement for Extended Memory Manager (EMM). Such a
statement should resemble the following example,

DEVICE = C:\DOS\EMM386.EXE X=D000-D7FF

2. If there is no similar DEVICE statement in your notebook
PC's CONFIG.SYS file, then edit the CONFIG.SYS file,
adding a statement copied exactly from the above example.

3. If there such a statement in CONFIG.SYS but the "DFE-650
PC Card not detected" error appears on each attempted Quick
Install run anyway, then edit that statement to read exactly the
same as the above example.

4. If, after you have completed the above instructions, the "DFE­650 PC Card not detected" error still appears on each
subsequent restart of the notebook PC, then please contact
your dealer or your nearest D-Link office, as listed at the end
of this User's Guide.

the Quick Install run. And the Quick Install run has indeed
produced a halt (system hangup).

If you have not been through all of those steps, then you should not
be reading this. You should be in the Software Installation section
of Chapter 2. And you should be staying on tra ck with your Quick
Install run. Continue reading here

only if

your Quick Install run is
actually obstructed by a system halt (so that you can only restore
your control of the notebook PC by a restart). And

only if

after
your restart (which provides assurance of a "clean" DOS
environment) you have tried Quick Install once more (and
experienced the system halt once more). Only then should you
conclude that you must "unload the conflicting network driver."

Stay Coo l

The first thing you need to know is that "unload the conflicting

network driver" is easier said than done. . . . This Trouble shooting

section will provide some guidance, and if you don't have a great
deal of experience in such matters, this guidance will be helpful.
But if you have easy access to a network administrator (or other
resident expert), now might be a good time to go for help. If it is
your choice to have a go at it alone, then don't be hurried or
worried. Just pour yourself a cup of coffee, relax, and read on. If
this Troubleshooting section is not sufficient guidance, and you do
not have ready access to an expert, then help may be available from
the dealer who has supplied your DFE-650, and you can also get
help by calling D-Link Technical Support at the D-Link office
nearest to you (see the list of office locations at the end of this
User's Gu i d e ) .

"Unload" Really Means "Avoid Loading at Startup"

It is true that driver programs and related software modules, such as
those supplied on your D-Link DFE-650 Series Fast Ethernet PC
Card Driver diskette, are often written so that the addition of a "/u"
switch or "-u" option to the command line for loading the driver

DFE-650 Series Fast Ethernet PC Card User's Guide

Troubleshooting

33

will cause unloading of the same driver (if it is in fact already
loaded). But such unloading is only possible under special
circumstances. So, as a practical matter, what we really must do is

avoid loading of the conflicting driver

upon startup of t he not ebook

PC.
A software installation procedure (such as "Quick Install 16-bit

Driver for DOS NetWare Client") copies the necessary drivers and
related modules from the supplied DFE-650 Series Fast Ethernet
PC Card Driver diskette, into the target directory of the notebook
PC's hard drive or other storage. The installation program also adds
commands to the computer's AUTOEXEC.BAT file, so that each
time the computer is subsequently booted up (and you then make
certain choices in the startup menus, if any), the drivers and related
modules are automatically loaded into memory.

The "conflicting driver" problem now at hand arises because certain
commands already present in your notebook PC's
AUTOEXEC.BAT file are being executed during bootup, and are
causing some kind of previously installed network driver module to
be loaded into memory. The presence of that network driver in
memory is now making i t impossible to load t he DFE-650 network
driver software (16-bi t drive r for DOS N etWare client).

So the fix is to delete from AUTOEXEC.BAT the line which is
causing the conflicting driver to be loaded. Thus we will

avoid

loading of the conflicting driver

when we next restart t he notebook
PC. And the trick is to delete that line from AUTOEXEC.BAT
without deleting or changing anything which needs to remain
unchanged in AUTOEXEC.BAT (so that your notebook PC will
behave as you expect it to after each startup).

So which line of AUTOEXEC.BAT do we need to delete?

Now there is a really good question! It gets right to the heart of the
problem. If you are savvy enough about such matters, then you
may be able to go directly into DOS Edit,

DFE-650 Series Fast Ethernet PC Card User's Guide

34

Troubleshooting

C:\> edit autoexec.bat

and find the troublesome line by inspection, and simply delete it.
But if you are that clever, then it is very unlikely that you will be
reading this. So here is a procedure which will help you to identify
the troublesome li ne of AUTOEXEC.BAT.

Use the

MEM

Command to Help Identify the Conflicting

Network Driver

At the DOS prompt (he re re prese nt e d by C: \>), type

C:\> mem /d | find "Program"

exactly as shown here, including the vertical bar (DOS "pipe"
symbol, |), then

<Enter>

. The resulting display of memory
allocation information will be a few rows of tabular data. Here is
an example:

0122E 80 (0K) MSDOS System
Program
01236 2,656 (3K) COMMAND Program
012F8 5,376 (5K) LSL Program
0144F 32,994 (32K) DFE650 Program
01718 16,640 (16K) IPXODI Program
01B28 48,688 (48K) NETX Program
0270B 29,024 (28K) SMARTDRV Program
02E2D 27,952 (27K) MSCDEX Program
03500 4,144 (4K) DOSKEY Program
03610 88,992 (87K) MEM Program

The next-last column lists the names of certain program modules
present in memory. We will disregard all the other columns.

DFE-650 Series Fast Ethernet PC Card User's Guide

Troubleshooting

35

Now we can cull that list of program names, by disregarding any
item which is obviously not the name of a network driver. You
might notice that some of the items (as in the example above) are
names of DOS commands. (A convenient way to determine
whether any item is the name of a DOS command is to search for
that name in the alphabetical index of DOS commands which
appears when you type "

help"

at the DOS prompt. ) Thus, i n our

example, we have a list of ten names, and we can

disre gard MSDOS, because it is the "System Program," and
thus is not a network driver

disregard COMMAND, because it appears in the
alphabetical list of DOS commands

disregard SMARTDRV, because it appears in the
alphabetical list of DOS commands

disregard MSCDEX, because it appears in the alphabetical
list of DOS c o mmands

disregard DOSKEY, because it appears in the alphabetical
list of DOS c o mmands

disregard MEM, because it appears in the alphabetical list of
DOS commands

This leaves us to deal with just four possibilities as to the name of
the network driver which is conflicting with our Quick Install:

LSL, DFE 650, IPXODI, a nd NE T X

Let's call this list the "short list." One of the items in the short list
is certain to be the conflicting driver.

Now It's Trial-and-Error Time

It is good news that the short list is short. The bad news is that
there is only one method guaranteed to determine which of the

DFE-650 Series Fast Ethernet PC Card User's Guide

36

Troubleshooting

items on the short list is the culprit (conflicting driver). And that
method is trial and error. So we begin testing each of the items on
the short list in turn. We take the items in the same order as they
appear in the short list (because taking them in that order will
ordinarily lead us to the earliest success). LSL is the first item on
our example short list, so we begin our trial-and-error round by
starting with LSL a nd foll owing t his proce dure :

1. Find the AUTOEXEC.BAT line which invokes the first item
in your short list (LSL in our e xam pl e):

At the DOS prompt (he re re prese nt e d by

C:\>

), type

C:\> find /n/i "LSL" autoexec.bat

then

<RETURN>. T

his will display the line from
AUTOEXEC.BAT which causes the LSL program to be
loaded.

---------- AUTOEXEC.BAT
[2]C:\ODI.DOS\LSL.COM

Ignore the heade r line of the display, whic h only identifi es t he
subject file. To help locate the LSL line of the
AUTOEXEC.BAT file, the line's line number in
AUTOEXEC.BAT is shown in brackets to the left of the
actual text of the line. If LSL appears in more than one line of
AUTOEXEC.BAT, then you will need to decide which of the
several lines is the one that causes loading –– but it is most
likely that any additional lines will simply be remark lines,
which you can ignore.

Note that in this step, you must name the first item of

your

short list, rather than LSL, which is used here only for
purposes of example.

2. Edit AUTOEXEC.BAT to cancel out that line.
At the DOS prompt (he re re prese nt e d by

C:\>

), type

DFE-650 Series Fast Ethernet PC Card User's Guide

Troubleshooting

37

C:\> edit autoexec.bat

then

<RETURN>.

The content of AUTOEXEC.BAT is
shown in the Edit window. Notice that the line number of the
cursor position is shown at the right end of the status bar (at
the foot of the Edit window; the line position of the cursor is
shown ahead of a colon, and the column position of the cursor
within the line is shown after the colon).

Take care

not to
introduce any inadvertent changes while you have
AUTOEXEC.BAT in the Edit window. Use the down arrow
key to move the cursor down until you reach the line number
as found in Step 1. Check t ha t t he li ne ma rke d by the c ursor is
the same as that displayed in Step 1. Then type in the word
REMARK at the beginning of the line. Immediately save,
then exit from Edi t .

3. Remove the D-Link DFE-650 Series Fast Ethernet PC Card
Driver diskette from its drive, and key

<CTRL + ALT +

DELETE>

to restart the note book PC.

4. At the DOS prompt, insert the D-Link DFE-650 Series Fast
Ethernet PC Card Driver diskette and run Installation Director,
again choosing

Quick Install 16-bit Driver for

DOS NetWare Client

and proceed with the installation run. If the installation run
completes normally, then you are all through with the
problem!

Give yourself a big pat on the back

, and return

"Installing 16-bit NetWare Client for DOS" in Chapt e r 3.

5. If the installation run again ends with a crash (halt), then the
short list item we have just tested (LSL in our example case)
is

not

the culprit. Repeat Step 1 above, but substitute the next
program named in your short list (in our example we
substitute DFE650 in place of LSL):

C:\> find /n/i "DFE650" autoexec.bat

Troubleshooting

Note that in this step, you must name the next item of

your

short list, rather than DFE650, which is used here only for
purposes of example.

6. Repeat Step 2 above, but before you REMARK the line which
invokes DFE650 (in the example case) you must

undo the

editing previously done in Step 2

. That is (in our example
case), delete the six letters REMARK from the beginning of
the line which invokes LSL (first item in

your

short list).
Then go ahead and REMARK the line which invoke s the next
program named in your short list (DFE650 in our example
case). Immediately save, then exit from Edit.

7. Repeat Step 3

8. Repeat Step 4

9. If necessary, repeat Step 5.

10. Repeat Step 6

If You're Still Reading . . .

It's hard to guess why you might still be reading this
Troubleshooting section, but maybe it's because you are still having
trouble. So here is a little bit of clarification to the above procedure
description. The example references (to LSL and DFE650) will
only be useful in getting started on the cyclic pattern of the above
instructions. After you are well into the rhythm of it, the example
references are best ignored because they are specifically
appropriate to the initial passes. By the time you get to testing the
third item in your short list, the example references in the above
description will be excess baggage –– refer only to

your

short list.

You Are Now an Un cert ified E xpert!

If you are not still having trouble, but you are still reading, then
maybe it is because you are simply excited about your success in

the above "trial by fire." You are excited about being an
Uncertified Expert. Congratulations! But, you ask: How is a
Certified E xpert a ny diffe re nt?

The difference is only this: certain items in your short list would be
old friends to the Certified Expert. He or she would have
recognized them by name just as surely as you know your friend's
face when you meet in a crowd. In the example case, the short list
included four items,

LSL, DFE 650, IPXODI, a nd NE T X.

The Certified Expert would have recognized NETX as a NetWare
shell module, therefore not the culprit conflicting network driver.
And the Certified Expert would have recognized LSL as most likely
being a link support layer module, which functions in a higher layer
of the communications system, while a hardware-specific network
adapter driver functions in a lower (physical) layer. And the
Certified Expert would have recognized or guessed that the
IPXODI module is a protocol-layer element concerned with the
transmission/reception of NetWare IPX packets by an ODI (Open
Data Interface) network adapter. Thus the Certified Expert would
have known, by a simple process of elimination, that the DFE650
element is the conflicting driver. So the Certified Expert would
have been able to skip the trial and error process, which we needed
to grunt through, in orde r to know which line of AUTOEXEC.BAT
to cancel.

And here is one more bit of insight. Since the conflicting driver
must be a hardware-specific driver, then it is likely to bear a name
which suggests the model name of the PC Card it serves. The
Certified Expert will be acquainted with a large range of PC Card
products. So he or she will be able to know which element in the
short list has a name which suggest s a PC Card model name. Now
you know what lies between you and being a Certified Expert.
