1) Installing the adapter drivers
You must install or update the base drivers according to the methods and
requirements specific to each operating system. You can find the installation
information for most popular operating systems in the user guide. See section
6 (Viewing the user guide).

2) Installing PROSet and advanced features in Microsoft Operating Systems
PROSet and other advanced features are available as separate installable
modules in this software release. You can install the advanced features only
AFTER you update the adapter drivers with the drivers found in this version.

To install advanced features, including PROSet, simply run SETUP.EXE from the
root of this archive. You will be presented with a list of installable
features. Many of the features are available in separate downloads. Note that
only those features that you have downloaded will be available for install.
See "Additional Software" below for more details.

In Windows NT* 4.0, PROSet will be installed automatically when you install

This version of the Intel(R) PRO LAN adapter driver software enables
simultaneous teaming and VLAN capabilities in Windows 2000.

PROSet and the base drivers are now installed separately in Windows 9x, Me
and Windows 2000. The MAKEDISK utility for these operating systems will only 
copy the base driver installation files to the floppy. To install the 
advanced networking features in these OS's, you must install them from a CD, 
hard drive, or over the network once you have established a network 

Starting with release 5.0, Windows 2000 IPSec encryption offload works for

To recreate the release 5.1.1 CD structure (minus the Linux and Unix files),
extract each archive into the same directory as this 100PDISK module. The final
directory structure should look like this:

C:\INTEL\ (or other directory path you chose to extract 100PDISK into)


Some of these directories may not be present, depending on the archive
modules you have downloaded and extracted.

There are some files that exist in more than one archive. When extracting an
archive per these instructions, the process may return a message indicating
that you are about to overwrite an existing file of the same name and prompt
for your approval. Choose "Yes" unless instructed otherwise.

To install these components in Windows, run SETUP from the root directory of
this download.

7) Errata and known issues


The Intel?PRO/100 Intelligent Server Adapter (PILA8480 only) is not
supported by this software release. Please see for the 
proper drivers.

In viewing the help for the advanced settings, you may notice some
inconsistencies between the help and the actual settings. Pressing the
Restore Default button will always take you back to the preferred default.


To update the drivers in Windows 98 SE to the drivers in this release, you
should first delete the existing drivers through the Network Control Panel or
Device Manager. Then restart the computer. When the computer detects the
adapter during Plug and Play installation on startup, use the drivers 
included with this archive.

Failure to follow this process may result in a message on reboot that the
device file WOL558.VXD is missing. See Microsoft Article Q242150.


When uninstalling a VLAN on a team in Windows NT 4.0, the 802.1Q tagging may
become disabled on remaining teams.  Windows will prompt for a reboot after
the VLAN is removed.  Choose No, then re-open PROSet and re-enable 802.1Q
tagging from the Advanced tab for each team member affected.  When prompted
for the reboot, choose Yes.

Under certain conditions on starting a service, you may receive an error in
the Event Log indicating NMSSvc cannot be found. This is a known cosmetic
issue and all services will run correctly.

See the file README.TXT in the root of this archive for more information.

8) Dual Port Server Adapter

Intel has combined security features with the ability to have two distinct
adapter ports in one PCI slot. The PRO/100 S Dual Port Adapter has a 64-bit
PCI connector, allowing the two 32-bit ports to operate with a 64-bit
bridge at 33 MHZ.

When installing a PRO/100 S Dual Port adapter, upgrade all Intel 10/100
adapters in the computer to the latest software. If the computer has trouble
detecting both ports, consider the following:

1. Your operating system may need to re-enumerate the bus. To force the re-
numeration, uninstall or unload the drivers for all PCI devices installed
and shutdown the computer. Then restart the computer and reinstall or reload
all drivers.

2. Some computers may need BIOS upgrades to properly detect the adapter's
bridge chip and both ports. 

3. The "Plug and Play OS" setting in the BIOS should be set to "Yes" for
Plug-and-Play operating systems such as Windows 2000 and set to "No" for
Windows NT and most other operating systems.
Adding this adapter through hot plug may present some difficulties. If your
second port is not detected, a restart may be required. When installing this
adapter in NetWare with hot plug, include the keyword "persist=1" in the
load line.
