Windows NT* 4.0 Installation Notes for the Intel EtherExpress(TM)
PRO/100+ PCI LAN Adapter
=================================================================
LOCATION OF DRIVER: \NT\E100BNT.SY_ (NDIS 4.0 compressed)
\OEMSETUP.INF
Note: NT 4.0 ships with a driver for the PRO/100B adapter.
However, it is recommended that you install the more recent
driver from the Configuration and Drivers disk.
General instructions
--------------------
After putting the adapter in the computer, you need to configure it under
Windows NT.
1 Double-click the Network icon in the Control Panel.
2 Select the Adapter tab and click Add...
3 Select Have Disk. Insert the Configuration and Drivers disk in the
disk driveand click OK.
4 Select "Intel EtherExpress PRO/100+ PCI Adapter (TX or T4)" from the
list of available drivers and click OK.
5 The PROSet setup utility automatically scans computer resources
and determines the settings assigned to your adapter. It also adds a
PROSet icon to the Control Panel for future use of PROSet.
6 (Optional) You can test the adapter by clicking the Test button.
7 To exit PROSet and finish installing the driver, click OK in the
PROSet main menu.
8 Select the protocol(s) required (TCP/IP is the default) by selecting
the Protocol Tab.
9 Select the network services required (by default, all are selected) by
selecting the Service tab.
10 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/100+ PCI 100Base-
TX, 10BaseT" adapter. Also, The NDIS 4.0 miniport driver will
automatically get installed in Windows NT 4.0.
11 When prompted, restart NT.
12 Repeat these steps for installing additional adapters.
Adapter Settings
================
There are two ways to run PROSet, which allows changing the adapter
settings.
- From the Control Panel double-click on the 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 PROSet menu click the Change button to get to the
Adapter Settings screen. The defaults work correctly for most
configurations.
Network speed
-------------
Recommended setting: Auto (default)
This parameter lets the PRO/100+ 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
-----------
Recommended setting: Auto
Auto: The adapter negotiates with the hub how to send/receive
packets, either full or half duplex.
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
switch.
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/100+ adapter has the ability to send and receive
packets at the same time (full-duplexing) at both 10 and 100 Mbps. In
order to reap the benefits of full duplexing, you MUST have a full
duplex switch.
The PRO/100+ adapter has the added ability to "talk" to the hub or switch
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 or switch and want to run at full duplex,
set Duplex Mode to Full and then set the SPEED parameter to either 100
Mbps or 10 Mbps.
Note: If you set duplex to Full, and leave Speed at Auto, the adapter
will run at 10 Mbps.
Advanced Adapter Settings
=========================
Click the Advanced button in the Adapter Settings screen to change the
Advanced setting.
Note: The defaults work correctly for most configurations. Please
use caution when changing these parameters. Use the online
help for additional information.
Coalesce buffers
----------------
Recommended setting: 8
Receive buffers
---------------
Recommended setting: 32
Transmit control blocks
-----------------------
Recommended setting: 16
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.
Adaptive Technology
-------------------
Recommended setting: On
Adaptive Technology customizes the PRO/100+ adapter to the respective
operating system by downloading microcode to the silicon. This improves
performance and minimizes CPU utilization.
Map Registers
-------------
Recommended settings: 64

Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
