PCI Technology
The PCI local bus is a high-performance bus that
provides a processor-independent data path between
the CPU in a PC and high-speed peripherals. This
interconnect mechanism is designed specifically to
accommodate multiple high-performance peripheral
devices that support networking and disk
subsystems, graphics, full-motion video, and
multimedia.
1-4
CHAPTER 1: INTRODUCTION
The PCI specification defines two types of PCI
devices: a target and a master. A target is a device
that accepts commands and responds to the
requests of a master. The master, or bus master, is a
more intelligent device that can conduct processing
independently of the bus or other devices. A bus
master device shares the bus with the main
processor and targets. Bus mastering allows a
peripheral device to take control of the system bus
and not rely on the central processor. The 3C971-F
adapter is a bus master device.
The PCI specification supports the following features:
■
High performance. The PCI local bus runs at a
clock speed of 33 MHz and employs a 32-bit data
bus that supports multiple peripheral components
and add-in cards at a peak bandwidth of 132 MBps,
up to an order of magnitude greater than that of
other PC buses (ISA, EISA, and MCA).
■
Automatic configuration. A PCI adapter has
configuration specifications set in on-board memory
and provides installation information to the computer
at start-up.
■
Shared slots. The PCI specification calls for
“shared slots,” which denotes the shared expansion
backplate slot. This shared backplate slot provides
access to one of two types of adapters: a PCI
adapter and an ISA adapter, for example, or a PCI
adapter and an EISA adapter. Only one adapter at a
time can be installed in a shared slot. Manufacturers
are currently producing computers that support the
PCI bus in conjunction with conventional ISA or EISA
buses in the same chassis.
For detailed information about the PCI local bus,
consult the PCI specification.

WINDOWS NT DRIVER
INSTALLATION
Overview
This chapter describes the procedure for installing a
3C971-F ATMLink PCI adapter driver for Microsoft¨
Windows NT™ 3.51 workstations. The 3C971-F
adapter driver provides standards-based ATM LAN
emulation connectivity to an ATM network. This
allows you to run legacy LAN applications, Ethernet
networking technologies and Ethernet protocols over
an ATM network.
The LAN emulation SVC driver utilizes signaling
software to establish connections between two end
stations on the ATM network. The driver operates
below the host’s Link Level protocol. It provides for
broadcast/multicast addressing, along with other
LAN-like services, so that host network protocols
function as if they were talking to a real MAC layer of
an Ethernet interface. Connections are set up and
torn down dynamically by the signaling software
provided with the 3C971-F adapter. Once the LAN
emulation server (LES) has been set up on the ATM
network, it is easy to add a LAN emulation client
(LEC) to the network.
CAUTION: Your ATM switch must be set to support
the UNI 3.0 standard for switched virtual circuits.
Multiple LAN Emulation Clients
The 3C971-F adapter can communicate with up to
four LAN emulation servers (LESs) at a time. During
installation of the hardware driver, four client
3-2
CHAPTER 3: WINDOWS NT DRIVER INSTALLATION
addresses, Client 0 through Client 3, are assigned
to the adapter. Each client has a MAC address, with
Client 0 being assigned the true MAC address of the
3C971-F adapter. Clients 1 through 3 have a virtual
MAC address, assigned by the driver, that is an
increment of the true MAC address. Duplicate MAC
addresses cannot occur on the network. The true
MAC assignments at the factory are spaced in
increments of 16 addresses. You are not required to
use the three additional clients. Client 0, however,
represents the true MAC addresses of the 3C971-F
adapter and cannot be disabled.
Each client can be set to contact (at bootup time) a
LAN emulation configuration server (LECS) using
the ATM Forum’s “well-known” LECS address. The
LECS contains all the necessary configuration
information for each client to connect to the
appropriate LAN emulation server. If an LECS is not
in use or not available on the network, the user can
set the client to contact an LES directly by entering
the LES’s 20-byte ATM address.
Installation Procedures Overview
The basic installation procedures for these drivers
are:
■
Verify the system requirements.
■
Install the adapter hardware driver.
■
Configure the PCI parameters.
■
Configure the signaling options.
■

CHAPTER 3: WINDOWS NT DRIVER INSTALLATION
Installing the Adapter Device Driver
The examples in this chapter use the Windows NT
environment to install the 3C971-F adapter driver.
However, the driver can be installed as part of the
Custom setup procedure supplied with your
Windows NT operating system. Refer to the Microsoft
Windows NT System Guide for additional
information.
The procedures within this chapter assume the
3C971-F adapter is already installed in the
workstation. If the adapter is not installed, refer to
Chapter 2 for hardware installation instructions.
CAUTION: If the 3C971-F adapter driver is already
installed, you must remove it before proceeding with
this installation. Refer to the section “Removing a
Windows NT Driver” at the end of this chapter for
instructions.
To install the 3C971-F adapter device driver for
Microsoft Windows NT version 3.51, follow these
steps:
1 Boot your system under Windows NT.
2 Log into your Windows NT Administrator
account.
3 At the Program Manager screen, select the
Control Panel icon.
4 Select the Network icon.

CHAPTER 3: WINDOWS NT DRIVER INSTALLATION
13 Edit the PCI adapter parameters.
The settings in the PCI Adapter Setup dialog box
(Figure 3-5) are temporary settings for Client 0 of the
3C971-F adapter. The LEC applications software,
presented later in this chapter, allows the user to
reconfigure Client 0, if need be, and to enable the
additional clients.
a Set an appropriate MTU Size for Client 0.
All nodes that are part of the same logical IP
subnet must use the same maximum transmission
unit (MTU) value. The default size is 1514 and is
recommended for communicating with Ethernet
hosts. If ATM nodes are the only end-nodes on
the network, a setting of 9K will dramatically
improve performance.
b Set the Interrupt Level.
If you want the operating system to pick an
interrupt level automatically (recommended), use
the Auto Detect setting. Otherwise, you must set a
specific interrupt level for the 3C971-F adapter.
If the driver fails to recognize the adapter with the
Auto Detect setting, you may need to select an
interrupt level that coincides with your system
BIOS.
14 When the editing of PCI parameters is complete,
select the OK button.

15 Edit the signaling transport items.
a Set debugAPI to OFF (default).
The debug option is used as a troubleshooting aid
for the 3C971-F adapter. If you experience
difficulty in establishing connections with other
nodes in the network, setting the debug option to
ON produces special messages from the driver
to assist in isolating the problem.
b Set RegisterLecs to ON (default).
In future implementations that support the LAN
emulation server (LES), this item enables or
disables whether the “well-known” address of the
LAN emulation configuration server (LECS) is
registered or not. As of this release of the
adapter, the setting has no effect upon the
adapter or the operation of the LAN emulation
clients.
c Set UniRev to UNI30 (default) or to UNI31.
This item identifies the UNI level of the signaling
software driver being installed. The UNI30 setting
specifies UNI version 3.0. If your ATM switch
supports UNI version 3.1, use UNI31 as the entry.

network interface appears, as shown in Figure 3-8.
Figure 3-8
TCP/IP Configuration with Sample Entries
18 Edit the TCP/IP parameters.
At this stage of the installation, only Client 0 is
enabled. Client 0 represents the true MAC address
of the 3C971-F adapter and must be configured to
your network before exiting the screen. The same is
true for any of the remaining clients that will be
enabled in the LEC configuration section later in this
chapter. If any of the clients are to remain disabled,
only the IP Address box need be completed. You
cannot exit the TCP/IP screen unless an IP address
entry exists for all four clients. If applicable, dummy
numbers can be loaded to the clients that will remain

CHAPTER 3: WINDOWS NT DRIVER INSTALLATION
disabled. IP addresses for disabled clients are
ignored during actual operation.
Contact your network administrator for the required
entries in the TCP/IP Configuration table. If needed,
refer to the Microsoft Windows NT System Guide for
additional information for selecting and entering the
TCP/IP configuration values.
To edit the TCP/IP Configuration screen, follow the
steps below:
a Select the client to configure in the Adapter list
box at the top of the screen.
You can configure the clients in any order you
wish; however, the recommended procedure is to
work Client 0 first.
b Enter the IP Address.
This is the Internet address for your host
machine. It is a unique 32-bit address that
identifies the network and your specific machine
on that network. The format is dotted decimal
notation in the form xxx.xxx.xxx.xxx, where xxx is
in the range from 0 to 255.
c Enter the Subnet Mask.
The mask is used to partition the IP address into
two parts: a network side and a host side. The left
side of the address, or most significant address
bits, is shared among all hosts attached to the
same physical network segment. The least
significant bits are unique for each host
belonging to that segment.
The appropriate subnet mask depends upon the
IP address assigned to your facility and the
number of different networks desired. For
example, if a Class B address of 123.1.0.0 is
assigned to your company, and no more than
255 hosts will be assigned to any physical
Installing the Adapter Device Driver
3-13
segment, then an appropriate net mask might be
255.255.255.0. Thus, all host systems sharing
common address values in the first three octets
would be attached to the same physical network
segment. This is commonly called a subnet or
sub-network. Assuming this scheme is consistent
throughout the company, up to 256 different
subnets are possible, each identified by a unique
number in the third octet of the IP address.
d Enter the Default Gateway.
If your local network has a gateway to other
networks, you must enter your network’s gateway
address to communicate with machines on the
other side. It is normally in the form of an IP
address identifying your network’s segment from a
router or other network device.
e Enter the Primary WINS Server.
This is the address of the primary name server
used for looking up host names belonging to the
local and connected networks. This field is not
required, but having a name server is useful for
managing a large network. Refer to your operating
system documentation for more details.
f Enter the Secondary WINS Server.
If the primary name server does not respond to
requests for host information, the secondary
server will be queried.
g Do one of the following:
■

Repeat substeps a–f for each of the clients that
will be enabled in the LEC configuration section
later in this chapter.
Repeat substep a (the IP address entry) for each
of the clients that will not be enabled in the LEC
configuration section later in this chapter. If

20 Select Restart Now to reboot the computer.
Go to the next section to continue the installation of
the 3C971-F adapter driver.
Configuring the LAN Emulation Clients (LECs)
The LEC applications software included with your
3C971-F adapter provides a method for allowing
one ATM adapter to communicate with up to four
LAN emulation servers (LESs) at a time. In a typical
LAN emulation network, the LAN emulation
configuration server (LECS) provides a central point
of contact for LAN emulation clients to obtain
configuration information. The LECS provides the
client with the MTU (Maximum Transfer Unit) size,
ELAN name, and ATM address for the host LES. If
your network does not contain an LECS, you have
the option for setting each client to contact and join
an LES directly instead of contacting the LECS.
Configuring the LAN Emulation Clients (LECs)
3-15
To configure the LAN emulation clients, follow these
steps:
1 Boot the computer under Windows NT.
2 Log into your Windows NT Administrator
account.
3 At the Program Manager screen, select the
Control Panel icon.
4 Select the Lecconf icon (shown at left) in the
Control Panel.
The dialog box in Figure 3-10 appears.
Figure 3-10
LEC Configuration
The LECCONF icon was inserted in the Windows NT
Control Panel during the installation of the hardware
driver in the previous section.
The ATM Adapter Interfaces box lists the ATM
adapter(s) installed in your computer. The example in
Figure 3-10 shows a 3C971-F adapter as ATM
Adapter 0 with a MAC address of 00:00:77:85:8b:4e.
5 Set the value in the Interrupt list box.
Select the same setting used in the PCI setup
routines of step 13 in the section “Installing the
3-16
CHAPTER 3: WINDOWS NT DRIVER INSTALLATION
Adapter Device Driver.” A default setting of Auto
Detect was recommended in that step.
The Interrupt entry in the LEC Configuration dialog
box is not “in addition” to the entry in the previous
PCI Adapter Setup dialog box. The edit is made
available in the LEC applications to give the user an
opportunity to change the interrupt setting after the
driver is installed. The PCI Adapter Setup dialog box
is not accessible by the user after the first reboot of
the computer.
6 Select the Configure button.
The dialog box in Figure 3-11 allows the user to set
the 3C971-F adapter to communicate with up to four
LAN emulation servers. Four MAC addresses
appear in the Client List box. The first, Client 0, is
the default MAC address of the 3C971-F adapter.
The other three MAC addresses are increments of
the default address. All settings in the LEC ATM
Adapter Configuration dialog box are tied to the client
highlighted in the Client List box.
If the 3C971-F adapter is to communicate with only
one LAN emulation server, then Client 0 is the only
client that needs to be configured. The remaining
three clients must be disabled. The default settings
for Client 0 that initially appear in the dialog box are:
■
Enable: Enabled (Client 0 cannot be disabled)
■
MTU Size: 1514 (recommended for communicating
with Ethernet hosts)
■
ELAN Name: (blank)
■
LECS/LES: set to contact the LECS
■
ATM Address: set to the ATM Forum’s “well-known”
address

LEC ATM Adapter Configuration
The information required for the client to contact the
LECS or the LES may vary according to the vendor
of the server. For example, if you select the LECS
option (radio buttons at bottom of dialog box in
Figure 3-11), 3Com’s Cellplex 7000™ requires both
the ELAN name of the LES you want the client to
join and the 20-byte ATM Address of the
configuration server. Refer to the documentation for
your server(s) to determine the specific
requirements.
7 Edit the LEC ATM Adapter items.
a Select the client in the Client List Box that you
want to configure.
You may configure the clients in any order that
you wish; however, Client 0 must be fully
configured before exiting the dialog box.
b Enable the client if desired.
Put an “x” in the Enable box (not editable for
Client 0). All settings in the dialog box are ignored
for any disabled clients.
3-18
CHAPTER 3: WINDOWS NT DRIVER INSTALLATION
Complete substeps c–f below for enabled clients.
Otherwise, go to substep a to select another client
or go to step 8 to exit the LEC ATM Adapter
configuration.
c Set the MTU Size.
This entry is used by the client to request an MTU
(Maximum Transfer Unit) size from the server. The
server, in turn, replies with an MTU equal to or
less than the requested value. All nodes that are
part of the same logical IP subnet must use the
same MTU size. Refer to your network
documentation to determine the appropriate
setting.
A setting of 1514 is recommended for ATM networks
that interface with an Ethernet LAN. If ATM nodes
are the only end-nodes on the network, a setting of
9K will dramatically improve performance.
d Enter the ELAN Name.
This is the network name of the server that you
prefer the client to join. Configuration servers,
such as the 3Com Cellplex 7000, require the
ELAN name of the LES you want the client to
join. Refer to your server documentation to
determine the specific requirements.
e Select the LECS/LES address option.
There are two radio buttons to set the type of
client contact at bootup.
■
LECS option: Contacts the LAN emulation
configuration server with the 20-byte address in

NETWARE 4.1 SERVER
DRIVER INSTALLATION
Overview
The 3C971-F ATMLink PCI adapter driver for file
servers running Novell® NetWare™ 4.1 provides
standards-based ATM LAN emulation connectivity to
an ATM network. This allows you to run legacy LAN
applications, Ethernet networking technologies and
Ethernet protocols over an ATM network. The
procedures in this chapter include all the necessary
steps to complete the installation process.
The NetWare driver utilizes switched virtual circuits
(SVCs) to establish connections between two end
stations on the network. The driver dynamically sets
up and tears down connections. For LAN emulation,
the driver provides for broadcast/multicast addressing
and other LAN-like services. This allows the host
protocols to function as if they were talking to a real
MAC layer of an Ethernet interface.
The 3C971-F adapter supports multiple Emulated
LANs (ELANs). A single 3C971-F adapter can have
up to four different MAC addresses and can thus
belong to four different ELANs simultaneously.
CAUTION: Your ATM switch must be set to support
the UNI 3.0/3.1 standard for switched virtual circuits.
Before installing the driver, review the README
document included with the software.
The basic installation procedures for the 3C971-F
adapter driver are:

Figure 4-8
Driver Protocols/Parameters Edit
The 3C971-F adapter can appear to the network as
a single adapter, or as multiple adapters. Channel 1
Configuring Network Channels
4-7
is always configured. When used to emulate multiple
adapters, channels 2 through 4 are also configured.
For LAN emulation services, each channel becomes
a LAN emulation client (LEC) and can be set to
contact the LAN emulation configuration server
(LECS), or set to contact a LAN emulation server
(LES) directly. In a typical LAN emulation network,
the LECS provides the client with a central point of
contact for obtaining the MTU (Maximum Transfer
Unit) size, ELAN name, and ATM address for the
LES the client is to join. In NetWare networks, the
MTU size is fixed at 1514 bytes and cannot be
changed by the user.
CAUTION: You must configure Channel 1, the
default channel, before exiting the
Protocols/Parameters dialog box in Figure 4-8. The
configuration procedure is the same whether single
or multiple channels are used. At the end of the
configuration procedure, you choose whether to exit
the setup or to continue configuring additional
channels.
To configure the channels for the 3C971-F adapter,
the driver files must be copied to the server as
described in the previous section, and you must be
at the Protocols/Parameters dialog box shown in
Figure 4-8. Follow these steps:
1 Select Select/Modify driver parameters and
protocols at the bottom of the dialog box.
The highlight bar moves to the TCP/IP option in the
Protocols box.
2 To change the protocol from the default (IPX)
protocol, select the desired protocol.
If TCP/IP is selected, the dialog box in Figure 4-9
appears. Edit the TCP/IP information as follows:
4-8
CHAPTER 4: NETWARE 4.1 SERVER DRIVER INSTALLATION
Figure 4-9
Configuring TCP/IP Network Interface
a Enter the IP Address.
This is the Internet address for the channel client.
The format is dotted decimal notation in the form
xxx.xxx.xxx.xxx, where xxx is in the range from 0
to 255.
b Enter the IP Mask.
The mask is used to partition the IP address into
two parts: a network side and a host side. The left
side of the address is shared among all hosts
attached to the same physical network segment.
The remainder of the mask is unique for each
host belonging to that segment. For example, if a
Class B address of 123.1.0.0 is assigned to your
company, and no more than 255 hosts will be
assigned to any physical segment, then an
appropriate net mask might be 255.255.255.0.
Thus, all host systems sharing the common
address 123.1.0.xxx would be attached to the
same physical network segment.
c Press [Enter] to save and exit the dialog box.
3 To change the IPX frame type from the default
(Ethernet 802.2) frame type, proceed as follows:

number 2, and so forth.
5 Enter ELAN Name.
This is the network name of the server that you
prefer the client to join. Configuration servers, such
as the 3Com Cellplex 7000™, require the ELAN
name of the LES that you want the client to join.
Other vendors may require only the 20-byte ATM
address of the LECS. Refer to your server
documentation to determine the specific
requirements.
6 Enter the LECS/LES network address.
The ATM network address is 20 bytes (40
characters) in length. The NetWare parameters are
restricted to a maximum of 35 characters. Therefore,
the network address entry for the server is divided
into two parts, the prefix entry and the ESI/SEL
entry. Refer to Figure 4-13.
Figure 4-13
LECS/LES ATM Network Address Entries
Configuring Network Channels
4-11
The last four selections in the Parameters box are
used to choose which type of server, LECS or LES,
the client is to contact at bootup, and to enter the
ATM network address of the server.
The term “prefix” in the parameter name refers to the
ATM prefix portion of an ATM Network address. The
prefix is thirteen bytes (26 characters) in length and
comes from the ATM switch. The term “ESI/SEL”
refers to the remaining seven bytes of the ATM
network address. It contains the 6-byte MAC address
of the server, followed by a 1-byte SEL (selector)
value.
Configure the four entries for each channel client as
follows:
■
If you want the client to contact the LECS with the
ATM Forum’s “well-known” address, do the following:
a Set all four entries to zero, if they are not set to
zero already.
This is the default setting of the parameters, as
shown in Figure 4-13.
b Go to step 7.
■
If you want the client to contact the LECS with an
ATM network address other than the ATM Forum’s
“well-known” address, do the following:
a Select LECS Network Prefix and enter the first 13
bytes (26 characters) of the LECS’s ATM network
address.
b Select LECS ESI/SEL and enter the remaining
seven bytes (14 characters) of the ATM network
address.
c Set the LES Network Prefix and the LES ESI/SEL
parameters to zero, if they are not set to zero
already.
4-12
CHAPTER 4: NETWARE 4.1 SERVER DRIVER INSTALLATION
d Go to step 7.
■
If you want the client to bypass the LECS at bootup
and contact the LES directly, do the following:
a Select LES Network Prefix and enter the first
thirteen bytes (26 characters) of the LES’s ATM
network address.
b Select LES ESI/SEL and enter the remaining
seven bytes (14 characters) of the ATM network
address.
c Set the LECS Network Prefix and the LECS
ESI/SEL parameters to zero, if they are not set to

does not boot up.
1 Check to see if the system is plugged in.
2 Check to see if your monitor is plugged into
your video adapter.
3 Check to see if the adapter card is properly
seated in the PCI bus expansion slot.
4 Try a different PCI slot.
5 Remove the adapter and see if the system
boots up and returns to a normal state of
operation.
Applications Problems
Problem
Possible Solution
A network
application no
longer works.
If the application program worked before the
installation of the adapter, there is probably a
hardware conflict.
Some programs that access the hardware can
cause a conflict at some point. This is typically
associated with hardware such as printers and
modems. If you suspect a hardware conflict,
check the PCI configuration that came with
your system to resolve the problem.
Adapter Problems
5-3
Adapter Problems
Problem
Possible Solution
Host adapter is
not found.
The PCI system in your computer is supposed
to configure the bus address locations
automatically. An address conflict is probably
not the problem. If the driver is correctly
installed, a driver message should appear in
the system driver event log after bootup of your
computer.
1 Make sure the adapter card is seated
correctly in the bus expansion slot. Try
another PCI slot. Try another adapter that is
known to operate correctly.
2 Check for correct configurations of the
network cable into the adapter card. Verify
the cable is properly connected at both
ends. If the cable is connected correctly, the
Link LED will be on.
3 Ping the failed system from another host on
the network.
4 Reseat the adapter card.
The card cannot
communicate with
other hosts on the
network.
1 Check the network cable and all connections.
2 Try to ping other hosts on the network from
your host computer.
