INTEL PRO/100 S AND SR MOBILE ADAPTER CHARACTERISTICS
=====================================================

This release of the PRO/100 Mobile Adapters have the following 
characteristics:

- Smart Powerdown-Extends battery life by putting the card into a 
  low power mode when the LAN cable is removed from the adapter.

- 10/100 Mbps connectivity - Allows portable PCs equipped with a 
  CardBus slot to connect to 100Base-TX Ethernet networks to take 
  advantage of higher network bandwidth.  

- The PRO/100 Mobile Adapter takes advantage of the PCI-based 32-bit 
  bus provided by the CardBus slot.  This eliminates the bottleneck of 
  a 16-bit bus, thus providing high-performance 100 Mbps networking.  
 
- Auto-negotiation of 10 or 100 Mbps Ethernet connection rate - Upon
  initialization, the adapter will automatically adopt the speed 
  of the network port to which it is attached, allowing it to be 
  used seamlessly on either 10 Mbps (10Base-T) or 100 Mbps 
  (100Base-TX) network segments.  

- On the LAN+Modem56 adapter, V.90 modem technology allows access to 
  information and e-mail on corporate networks, the Internet, and other
  online services at speeds up to 56Kbps over standard phone lines.
  The V.90 mode enables speeds up to 56Kbps when data is downloaded.
  Upstream data sent from the user travels at the standard V.34 
  rate.  The modems at both ends of the call must be V.90 
  compatible to achieve 56K speeds, if not, they will negotiate a 
  standard V.34 connection.

Making Floppy Disks for Installation 
------------------------------------

If you need to use a floppy disk to install the adapter drivers,
click the Create Install Disk button on the Intel CD autorun 
screen.  The Create Install Disk utility appears, and you can follow 
on-screen prompts for creating the installation disk of your choice.
(Make sure you have a blank 1.44 MB formatted, non-bootable diskette
in the floppy drive when using this utility.)

Installing PROSet II and Other Advanced Features
------------------------------------------------

The Intel CD includes an installation utility for installing 
Advanced Features, which may include the following (your 
adapter may not support all these features):

  - Intel(R) PROSet II control panel utility
  - Desktop Management Interface (DMI)
  - Intel(R) PRO Network Adapters WMI Provider 
  - Intel(R) PRO Quality of Service WMI Provider 
  - Intel(R) PRO/100 LAN Adapters SNMP 
  - Intel(R) PRO/100 Mobile Modem Utilities

For Windows* 95, only Intel(R) PROSet is available.

When you insert the Intel CD in the CD-ROM drive, the Autorun screen 
appears.  Select "Install Drivers and Utilities" to start the installer.

Alternately, you can start the installer by double clicking AUTORUN.EXE
in the root directory of the Intel CD.

You can also install drivers without PROSet by selecting "Install Base 
Driver Only" on the Autorun screen menu.

Upgrading to Windows 2000 or XP from prior version of Windows
-------------------------------------------------------------

If you are upgrading from a prior version of Windows to Windows 2000 or 
Windows XP and you have Intel PROSet software installed, access to PROSet 
may be disabled during the upgrade process.  You will need to reinstall 
Intel PROSet software as using the instructions above or those in the 
online User's Guide.

Updating Software and Drivers in Windows 98
-------------------------------------------

If you're using Windows 98 and have updated or added an adapter, 
you may experience a problem with device driver update files not being
copied.  (This is a known problem, for which Microsoft has published a
Knowledge Base article, Q242150.)

To resolve this problem, perform the following:

1.  Reboot the computer.

2.  Remove the adapter via Device Manager and reboot the computer again.

3.  When prompted for the adapter driver, choose the option "Display a
    list of all the drivers...".  Then choose the adapter from the list
    and click Have Disk to update the drivers from the Intel CD.

4.  Reboot the computer.


NOTES ON CARD SERVICES
======================

Windows NT 4.0 
--------------

- The PRO/100 Adapter is not compatible with NT 4.0 Card Services
  requiring support for PCMCIA proposal 187.

- SystemSoft CardWizard* versions 4.1 and higher is now 
  compatible with CardBus II adapters      

- Phoenix CardWare supports the LAN function only.  


KNOWN LIMITATIONS
=================

- In order to connect to a 100Base-TX Ethernet network, a Category 5
  unshielded twisted pair (UTP) network cable terminating in a male
  RJ-45 connector must be connected to a 100Mbps hub or switch.  Check
  with your LAN Administrator if you are not certain of your network
  speed and infrastructure.

- The PRO/100 Mobile Adapter is designed to connect to a 100Base-TX 
  network.  It does not support 100VG-AnyLAN networks.     

- If you are attempting to use the PRO/100 Mobile Adapter in a port 
  replicator or docking station, are using Windows 95 and are having 
  problems, there are three alternatives: 

  1.  Put the adapter in the notebook rather than the replicator or
      docking station
  2.  Manually load the drivers
  3.  Use Windows 98 or Windows Me as these appear to support this
      environment better than Windows 95.

- When attempting to use the PRO/100 Mobile Adapter with a 16-bit 
  adapter (e.g.  modems, flash cards, ATA cards) in the other slot, it 
  may be necessary to start up with only the PRO/100 adapter installed, 
  then hot-insert the second adapter.

- On the Combo adapter, to achieve 56 Kbps speed, there can be only one
  digital to analog conversion between the connecting modems.
  Also, the modems at both ends of the call must be .V90 or K56flex
  compatible to achieve 56K speeds, if not, they will negotiate
  a standard V.34 rate.  Current FCC regulations limit download
  speeds of the modem to 53Kbps.

- When running MS-DOS, the PRO/100 Mobile Adapters must be initialized
  by running the CBCOMBO.EXE utility, which can be found in the CARDBUS/DOS 
  folder on the Intel CD.  Usage is as follows:

   CBCOMBO [Optional parameters]

  For the NDIS 2 DOS driver E100B.DOS the CBCOMBO utility must be run from 
  the CONFIG.SYS file during system startup.  The usage for this method is as 
  follows:
   DEVICE=\path\CBCOMBO.EXE  [optional parameters]
       
 Simultaneous dual mode operation of the LAN and Modem functions has limited
 support in the DOS environment.  The CardBus II adapter requires that both 
 the LAN and modem function share the same hardware interrupt.  Most DOS-
 based LAN and modem communications applications were developed before the 
 PCI bus made interrupt sharing possible and therefore have no support for 
 interrupt sharing.  Using the 16-bit ODI driver, specify either NOCOM or 
 NOLAN when loading the CBCOMBO utility.  The 32-bit ODI driver does not 
 support modems.


CARDBUS-EQUIPPED PORTABLE COMPUTERS
===================================

The PRO/100 S Mobile Adapter requires a portable computer with a CardBus 
PC Card Slot.  Most laptops introduced after January 1997 incorporate
CardBus PC Card slots.  If you're not sure if your system supports
CardBus, contact the manufacturer of your laptop.


MODEM INFORMATION
=================

For general information on AT commands see the PRO/100 Mobile Adapters 
User's Guide.  For information on configuring the modem for use with the 
V.90 protocol, see the next topic.

S109 REGISTER
-------------

The firmware contained in this product is designed to initially 
attempt to make a v.90 connection, and then fall back to K56flex if 
the host being dialed does not support v.90.  However, the host being
dialed must support v.90 auto-detect in order for a v.90 connection
to be initiated by default.  

Please note that if this command is used and a v.90 connection is
not achieved the modem will fall back directly to v.34.  When S109=2,
fall back from v.90 to K56Flex is disabled.  To set this value back
to the default issue an ATS109=1 command.  

In summary, the values of this register and the resultant behavior
are:

S109=1 (default) - Negotiates initially at v.90 if host supports
                   v.90 auto-detect.  If host does not support 
                   v.90 auto-detect or does not support v.90 at
                   all, will negotiate back to K56flex.
S109=2           - Forces v.90 for PCM connects.  If host does not
                   support v.90, falls directly back to v.34.

Changing the value of the S109 register can be implemented via the 
following means:

- When using a terminal emulator program, enter ATS109=n (where n is 
  the value desired).

- To implement with Windows 95/98/W2k/Me/NT dial up networking, go to
  Control Panel\Modems.  Highlight the modem and click Properties.
  Click Connection\Advanced.  Enter S109=n (where n is the value
  desired) in the Extra Settings box.
