Windows NT* 4.0 installation notes for Intel's EtherExpress(TM) PRO/100B
LOCATION OF DRIVER: \NT\E100BNT.SY_ (NDIS 4.0 compressed)
Note: NT 4.0 ships with a driver for the PRO/100B. However, it is
recommended that you install the more recent driver contained
on the Configuration and Drivers diskette.
After putting the adapter in the computer, you need to configure it under
1 Double-click the Network icon in the Control Panel.
2 Select the "Adapter" tab and click Add...
3 Select Have Disk. Insert the PRO/100B Drivers Disk in the disk driver
and click OK.
5 Select "Intel EtherExpress PRO/100B PCI Adapter (TX or T4)" from the
list of available drivers and click OK.
6 The Intel PROSet Setup program automatically scans computer resources
and determines the settings assigned to your adapter. It also adds an
Intel PROSet icon to the Control Panel for future use of PROSet.
7 (Optional) You can test the adapter by clicking the Test button.
8 To exit PROSet and finish installing the driver, click OK in the
PROSet main menu.
9 Select the protocol(s) required (TCP/IP is the default) by selecting
the Protocol Tab.
10 Select the network services required (by default, all are selected) by
selecting the Service tab.
11 Click Close to continue. Other Configuration screens may appear.
configure as desired.
Note that after the driver is installed, NT may show the adapter as
"Intel 82557-based 10/100 Ethernet PCI Adapter". PROSet will display
the adapter specifically as "Intel EtherExpress PRO/100B PCI 100Base-
TX, 10BaseT" adapter. Also, The NDIS 4.0 miniport driver will
automatically get installed in Windows NT 4.0.
12 When prompted, restart NT.
13 Repeat the General Instruction process for installing additional
There are two ways to run PROSet, which allows changing the adapter
- From the Control Panel double-click on the Intel PROSet icon.
- From the Control Panel, double-click on the Network icon, select the
adapters section, and double-click on the "Intel 82557-based 10/100
Ethernet PCI adapter".
From the main Intel PROSet menu click the Change button to get to the
Adapter Settings screen. The defaults work correctly for most
Recommended setting: Auto (default)
This parameter lets the EtherExpress PRO/100B adapter know what speed to
use on the Ethernet wire. The choices are 10 Mbps, 100 Mbps, and Auto.
In Auto mode, the adapter detects if its environment can support 100 Mbps
speed. It then sets the speed to 100 if it can, or 10 if it can't. If you
are using a cross over cable connected to another adapter, set the speed
to either 10 Mbps or 100 Mbps.
Note: If the Duplex Mode is not set to Auto, then set the speed to
either 10 Mbps or 100 Mbps.
DUPLEX MODE (100BASE-T4 does not support full duplex)
Recommended setting: Auto (PRO/100B TX adapter only)
Auto: The adapter negotiates with the hub how to send/receive
packets, either full or half duplex. The PRO/100B T4 adapter
does not support auto-negotiating.
Full duplex: The adapter sends and receives packets at the same
time. This improves the performance of your adapter. Set
duplex mode to full duplex only if you have a full duplex
Half duplex: The adapter performs one operation at a time. It
either sends or receives.
A regular adapter can perform only one operation at a time (half-
duplexing). The PRO/100B TX adapter has the ability to send and receive
packets at the same time (full-duplexing) at both 10 and 100 Mbps. The
PRO/100B T4 adapter supports full duplex only at 10 Mbps. In order to
reap the benefits of full duplexing, you MUST have a full duplex switch.
The PRO/100B adapter has the added ability to "talk" to the hub and
determine at which mode to communicate (either full or half duplex). This
is called auto-negotiation. You must have an auto-negotiating switch to
get full duplex support with the Duplex Mode set to Auto. If you don't
have an auto-negotiating hub and want to run at full duplex, set Duplex
Mode to Full and then set the SPEED parameter to either 100 Mbps
(PRO/100B TX) or 10 Mbps (PRO/100B TX or T4).
Note: If you set duplex to Full, and leave Speed at Auto, the adapter
will run at 10 Mbps.

ADAPTIVE TRANSMIT THRESHOLD
Recommended setting: On
This parameter dynamically optimizes the point at which early transmit
cycles will be executed. This results in higher performance but may
generate an occasional underrun. To eliminate underruns, set it to OFF.
Recommended setting: On
Adaptive Technology customizes the PRO/100B adapter to the respective
operating system by downloading microcode to the silicon. This improves
performance and minimizes CPU utilization.
