Put the Adapter in the Computer  
1
Turn off the computer and unplug the power cord. Then remove its cover.  
Warning: Turn off and unplug power to the computer before  
removing its cover. Failure to do so could shock you and may  
damage the adapter or computer.  
2
Remove the cover bracket from a PCI busmaster adapter slot. In most  
computers, all slots are busmaster-enabled. If you have configuration  
problems, see your computer’s documentation to determine if the PCI  
slots are busmaster-enabled.

Connect the Network Cable  
1
Connect a single network cable to the PRO/100B TX PCI adapter as  
shown below. For 100BASE-TX, your network cable must be four-pair,  
category 5, twisted-pair wiring. If you plan on running the adapter at 100  
Mbps, it must be connected to a 100BASE-TX hub (not a 100BASE-T4  
hub). For 10BASE-T, use two-pair wiring.  
100BASE-TX Wiring  
Twisted Pair Ethernet (TPE).  
Use category 5 cable and RJ-45  
connector for this adapter. Do not  
use category 3 wiring. At 100  
Mbps, connect to a TX hub, not a  
T4 hub. For full duplex, see  
instructions on page 11.  
For more information on 100BASE-TX wiring requirements and limita-  
NOTE:  
tions, see page 18 in this guide and refer to the README files on

Troubleshooting  
If you can’t connect to a server, first try the suggestions here, then turn to  
page 14.  
Make sure you’re using the drivers for this adapter. The driver filename  
contains the letter B (for example, E100BODI.COM).  
If you’re replacing an existing adapter, make sure the LINK statement in  
your NET.CFG is correct for the new adapter. For example, the LINK  
statement for a NetWare client should be:  
LINK DRIVER E100BODI  
Verify that the frame type in your NET.CFG file matches your network.  
If setting up a server, check your LOAD and BIND statements.  
Test the adapter by running diagnostics in Setup. Additional testing is  
available by using a responder (see below).  
Check the README files (see page 1 for instructions).

Installing Multiple Adapters  
All users: The adapter’s 12-digit, hexadecimal Ethernet address is on a  
sticker near the edge of the adapter. The Ethernet address is sometimes called  
the node address or the MAC address. Note that the PCI slot number may not  
correspond with the physical connector in your computer.  
NetWare users: The server drivers use the PCI slot number to identify each  
installed adapter. You can correlate the PCI slot number to the adapter by  
using the Ethernet address that is printed on a label on the adapter. Run Setup  
from the Intel disk to view the Ethernet address and slot number for each  
installed adapter. For more information, see the README files. NetWare 4.11  
server installations use unique slot numbers that are assigned during sever  
setup.  
Windows NT and Windows 95 users: Repeat the configuration procedure  
for each adapter you want to install (add only one adapter at a time). While  
PROSet can detect all the PRO/100B adapters in your computer, you still  
need to perform the configuration process on each adapter. In Windows NT,  
be sure to click the Show all PRO Adapters box in the Configuration window.  
See the README file for more information.  
Select Duplex Mode (optional)  
Duplexing is a performance option that lets you choose how the adapter sends  
and receives data packets over the network. The PRO/100B TX adapter can  
operate at full duplex only when connected to a full duplex 10BASE-T or  
100BASE-TX switching hub. To summarize:  
Auto (requires a full duplex switching hub with auto-negotiation  
capability). The adapter negotiates with the hub to send and receive  
packets at the highest rate. This is the default setting. If the hub does not  
provide auto-negotiation, the adapter runs at half duplex.  
Full duplex (requires a full duplex switching hub). The adapter can  
send and receive packets at the same time. This mode can increase  
adapter performance capability. If the full duplex hub provides auto-  
negotiation, the adapter runs at full duplex. If the full duplex hub does  
not provide auto-negotiation, you need to set the adapter duplex mode  
manually (see following paragraphs)  
Half duplex. The adapter performs one operation at a time; it either  
sends or receives.  
NOTE:  
If your hub is running at 100 Mbps and half duplex, your potential  
bandwidth is higher than if you run at 10 Mbps and full duplex.  
11  
 
Manually Configuring for Full Duplex  
If your switch supports auto-negotiation with the N-way standard, duplex  
configuration is automatic and no action is required on your part. However,  
few switches in the current installed base support auto-negotiation. Check  
with your network system administrator to verify. Most installations will  
require manual configuration to change to full duplex.  
Configuration is specific to the driver you’re loading for your network  
operating system (NOS), as shown in the following paragraphs.  
To set up the duplex mode, refer to the section below that corresponds to your  
operating system.  
Adapter performance may suffer or your adapter may not operate  
NOTE:  
if your hub does not support full duplex and you configure the  
adapter to full duplex. Leave the adapter on half duplex if you are  
not sure what type of hub you are connected to.

steps are required for this adapter. Refer to the Windows 95 README file  
under the Microsoft section of Installing EtherExpress PRO/100B adapter  
drivers.  
13  
 
Troubleshooting  
If the adapter can’t connect to the network  
Make sure the cable is installed properly.  
The network cable must be securely attached at both RJ-45 connections  
(adapter and hub). If the cable is attached but the problem persists, try a  
different cable. The maximum allowable distance from adapter to hub is 100  
meters.  
If you’re directly connecting two computers (no hub), use a crossover cable.  
Most hubs require a straight-through cable, while most switches require a  
crossover cable (see your hub or switch documentation to verify).  
See the Cabling Information README file for more information on cross-  
over cables.  
Check the LED lights on the adapter.  
The EtherExpress PRO/100 TX PCI adapter has three diagnostic LEDs above  
the cable connector. These lights help indicate if there’s a problem with the  
connector, cable, or hub. The table on the next page describes the LEDs.

Make sure you’re using the correct drivers.  
Make sure you’re using the drivers that come with this adapter. The driver  
filename contains the letter B (for example, E100BODI.DOS). Drivers that  
support previous versions of the EtherExpress PRO/100 PCI adapter do not  
support this version of the adapter.  
Make sure the hub port and the adapter have the same  
duplex setting.  
If you configured the adapter for full duplex, make sure the hub port is also  
configured for full duplex. Setting the wrong duplex mode can degrade  
performance, cause data loss, or result in lost connections.  
Testing the adapter  
Test the adapter by running Intel diagnostics. For DOS or Windows 3.1  
computers, run Setup on the Intel Drivers and Configuration disk. For  
Windows NT and Windows 95 run Intel PROSet by double-clicking the Intel  
PROSet Icon in the Control Panel. Click Help from the main PROSet window  
to get complete diagnostics information and instructions.  
Common problems and solutions  
SETUP.EXE reports the adapter is “Not enabled by BIOS”.  
• The PCI BIOS isn’t configuring the adapter correctly. Try the PCI  
installation tips on page 17.  
15  
 
The computer hangs when the drivers are loaded.  
• Change the PCI BIOS interrupt settings. See the next page for PCI  
installation tips.  
• If you are using EMM386, it must be version 4.49 or newer (this version  
ships with MS-DOS 6.22 or newer).  
Diagnostics pass, but the connection fails or errors occur.  
• Make sure you are using category 5 wiring and the network cable is  
securely attached.  
• For NetWare clients, make sure you specify the correct frame type in your  
NET.CFG file.  
• Make sure the duplex mode setting on the adapter matches the setting on  
the hub.  
• At 100 Mbps, connect to a 100BASE-TX hub only (not T4).  
The LNK LED doesn’t light.  
• Make sure you’ve loaded the network drivers.  
• Check all connections at the adapter and the hub.  
• Try another port on the hub.  
• Make sure the duplex mode setting on the adapter matches the setting on  
the hub.  
• Make sure you have the correct type of cable between the adapter and the  
hub. 100 BASE-TX requires four pairs. Some hubs require a crossover  
cable while others require a straight-through cable. See the Cabling  
README file for more information on cabling.  
The ACT LED doesn’t light.  
• Make sure you’ve loaded the correct network drivers.  
• The network may be idle. Try accessing a server.  
• The adapter isn’t transmitting or receiving data. Try another adapter.  
• May not be using four-pair cable for TX wiring.  
The adapter stopped working when another adapter was added to the  
computer.  
• Make sure the cable is connected to the EtherExpress PRO/100 TX PCI  
adapter.  
• Make sure your PCI BIOS is current. See page 17 for PCI installation tips.  
• Make sure the other adapter supports shared interrupts. Also, make sure  
your operating system supports shared interrupts — OS/2* doesn’t.  
• Try reseating the newest adapter.  
The adapter stopped working without apparent cause.  
• Try reseating the adapter first, then try a different slot if necessary.  
• The network driver files may be corrupt or deleted. Delete and then  
reinstall the drivers.  
• Try a different PRO/100 TX PCI adapter.  
• Run the diagnostics.

Technical Information  
PCI Installation Tips  
PCI computers are designed to automatically configure add-in cards each time  
the computer starts. Your PCI computer sets the I/O address and IRQ level for  
your Intel network adapter when the computer starts. These values cannot be  
changed by Intel adapter software. If you experience a problem when the  
computer starts, additional configuration steps may be required.  
On these computers, manual configuration is possible through the computer’s  
PCI BIOS setup utility. Refer to your computer’s documentation. You may  
need to verify or change some BIOS settings.  
Some common PCI solutions are listed here.  
Busmaster enabled slots. On some computers, all slots are not  
busmaster enabled by default. Check your BIOS PCI bus setting. It will  
set to either Busmaster or Non-busmastered. Choose Busmaster.  
Reserve interrupts (IRQs) and/or memory addresses for ISA  
adapters. This prevents PCI cards from trying to use the same settings  
ISA cards are using. Check your PCI BIOS setup program. There may be  
IRQ options such as ‘Enable for ISA,’ ‘Reserve for ISA,’ or ‘Disable for  
PCI.’ This option is sometimes in the Plug and Play area of the BIOS  
setup.  
Enable the PCI slot. In some PCI computers, you must use the PCI  
BIOS setup program to enable the PCI slot. This is especially common in  
PCI computers with the Phoenix BIOS.  
Update your PCI BIOS. An updated PCI system BIOS can correct some  
PCI configuration problems. Call your computer manufacturer to see if  
an updated BIOS version is available for your computer. Phone numbers  
for the top PCI computer manufacturers are listed in the PCI Installation  
README file on the Intel Configuration and Drivers disk.  
Configure the slot for level-triggered interrupts. The slot the adapter  
is using must be configured for level-triggered interrupts rather than  
edge-triggered interrupts. Check your PCI BIOS Setup program.  
Here are some example PCI BIOS setup program parameters:  
PCI slot #:  
Master:  
Slave:  
Slot where the adapter is installed  
ENABLED  
ENABLED  
Latency timer: 40  
Interrupt:  
Edge-level:  
Choose an IRQ from the list  
Level  
The exact wording of these parameters varies with different computers.

Fast Ethernet Wiring  
100BASE-TX Specification: The 100BASE-TX specification supports 100  
Mbps transmission over two pairs of category 5 twisted-pair Ethernet (TPE)  
wiring. One pair is for transmit operations and the other for receive  
operations. Segment lengths are limited to 100 meters with 100BASE-TX for  
signal timing reasons. This complies with the EIA 568B wiring standard.  
Fast Ethernet Hubs and Switches  
The two basic types of hubs are shared hubs and switching hubs. Ether-  
Express PRO/100 TX adapters can be used with either type of hub for 10  
Mbps. At 100 Mbps, a TX hub or switch is required.  
Shared hubs  
In a shared network environment, computers are connected to hubs called  
repeaters. All ports of the repeater hub share a fixed amount of bandwidth, or  
data capacity. On a 100 Mbps shared hub, all nodes on the hub must share the  
100 Mbps of bandwidth. As stations are added to the hub, the effective band-  
width available to any individual station gets smaller. Shared hubs do not  
support full duplex.  
Think of a shared repeater hub as a single-lane highway that everyone shares.  
As the number of vehicles on the highway increases, the traffic becomes con-  
gested and transit time increases for individual cars.  
On a shared hub all nodes must operate at the same speed, either 10 Mbps or  
100 Mbps. Fast Ethernet repeaters provide 100 Mbps of available bandwidth,  
ten times more than what’s available with a 10BASE-T repeater.  
Repeaters use a well-established, uncomplicated design, making them highly  
cost effective for connecting PCs within a workgroup. These are the most  
common type of Ethernet hubs in the installed base.  
Switching hubs  
In a switched network environment, each port gets a fixed, dedicated amount  
of bandwidth. In the highway scenario, each car has its own lane on a multi-  
lane highway and there is no sharing.  
In a switched environment, data is sent only to the port that leads to the pro-  
per destination station. Network bandwidth is not shared among all stations,  
and each new station added to the hub gets access to the full bandwidth of the  
network.  
If a new user is added to a 100 Mbps switching hub, the new station receives  
its own dedicated 100 Mbps link and doesn’t impact the 100 Mbps bandwidth  
of another station. Switching hubs can effectively increase the overall  
bandwidth available on the network, significantly improving performance.  
Switching hubs can also support full duplex.
