1)  INTEL PRO/100 S Mobile ADAPTERs CHARACTERISTICS
    ================================================

    This release of the PRO/100 S 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.

    -All PROS/100 S family adapters have the ability to perform IPSec 
     offloading.  This feature moves the computation required for packet
     encryption to the card, freeing up your systems's CPU for other
     tasks,and resulting in a significant improvement in bandwidth
     and CPU utilization in an IPSec-secured network.
   
    -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 S 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.



2)  DETERMINING YOUR VERSION OF WINDOWS 95
    ======================================

    Follow the steps below to determine which version of Windows 95 you 
    are running:

        1  Click on the Start button.
        2  Select Settings.
        3  Select the Control Panel.
        4  Double-click on the System icon. The System Properties dialog 
           box opens.
        5  Select the General tab. Information about your system is 
           displayed, including the version of Windows 95 you are 
           running, under System.

    If 4.00.950 or 4.00.950A is indicated, your version is not supported by 
    the PRO/100 S Adapter. If 4.00.950B, 4.00.950C or later is reflected, then
    the adapter will work in this environment.  


3)  USING THE PRO/100 S Mobile IN WINDOWS 95 OSR2 (950B) and LATER
    =================================================================

    Intel Enhancements for OSR2
    ---------------------------
    Windows 95 version OSR2 (950B) and later support Plug and Play of 
    CardBus devices. However, OSR2 may have problems properly 
    allocating resources to some CardBus multifunction (Ethernet+Modem) 
    devices. The PRO/100 includes software which enhances the ability 
    of Windows 95 OSR2 to support CardBus multifunction devices. 
    This support is implemented in the NDIS4 driver (E100BNT.SYS) and
    E100BCFG.EXE.
    
    E100BCFG.EXE is a configuration program that helps Windows 95 OSR2 
    configure and use the PRO/100 S Mobile Adapter. It is launched after modem 
    installation, following restart. The only indication 
    that it has run will be a dialog box telling the user to restart to
    complete the installation.

    On some machines, the program will detect that particular VxD 
    files from Microsoft may be out of date. If this happens, the 
    user will be informed that it might help to obtain more 
    recent versions of these files. The specific files are:
    CBSS.VXD, PCI.VXD and PCCARD.VXD. Check with your computer
    manufacturer to see if they have any of these updates for your
    computer model. 

        NOTE: DO NOT update these files unless you are experiencing
              problems with the adapter, and you have reviewed the 
              troubleshooting information in the User's Guide. 

    In order to function with Windows 95 OSR2, E100BCFG.EXE places a 
    "forced configuration" onto the slot where the card is inserted.  
    Once this forced configuration is applied, no other card can be 
    inserted into that slot. However, the PRO/100 S Mobile Adapter can still be 
    removed and reinserted into the same slot while the laptop is
    running. The adapter should not be installed into the other slot.

    The forced configuration on the slot can be removed at a later time 
    by running E100BCFG manually (see section on Removing the 
    Forced Configuration below.)

    Removing the Forced Configuration
    ---------------------------------
    The forced configuration on the slot can be removed by running 
    E100BCFG manually. It can be found in the \INTEL\M32AAPPS directory.  
    When double-clicked, the E100BCFG displays a dialog box describing 
    the forced configuration information. Pressing the "Remove 
    Forced Configuration" button will restore the slot to normal.  

    Removing the forced configuration should be done before upgrading to 
    Windows 98 or Windows Me.  
    
    Known Limitations in Windows 95 OSR2
    ------------------------------------
    -Under Windows 95 OSR2, once the PRO/100 S Adapter is installed, no 
     other card can be inserted into the slot where the PRO/100 has been 
     inserted. However, the PRO/100 adapter can be removed and 
     reinserted into the  same slot while the laptop is running. The 
     adapter should not be installed into the other slot, since it would 
     cause a reinstallation of the adapter.

    -Windows 95 may fail to reinitialize the PRO/100 driver when Windows 
     95 comes out of Suspend/Resume.  To make the driver reload in this 
     situation, click on the PC Card (PCMCIA icon) in Control Panel, 
     highlight the adapter and click on Stop. Next, eject the PRO/100 
     adapter and then re-insert it. The PRO/100 S Adapter will now load.

    -When using Windows 95 OSR2, Toshiba Tecra 500 series 
     laptops require BIOS version 5.7 or later. 

    Upgrading from Windows 95 to Windows 98 or Windows Me
    ---------------------------------------
    -If the PRO/100 S Adapter is installed in Windows 95 OSR2 and you are
     upgrading to Windows 98 or Windows Me, the E100BCFG is not needed
     and the "forced configurations" it creates must be removed. See
     the section above titled "Removing the Forced Configuration" for
     instructions on how to remove it. 


4)  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 CardBuss II adapters
      

    -Phoenix CardWare supports the LAN function only.

    E100B.DOS       DOS NDIS 2 driver.
    CE100B.LAN      ODI C-Specification driver for NetWare 5.0 Server.


    Known Limitations
    -----------------
    -For Windows 95 OSR2 issues, see section 3 above on Windows 95
  
    -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 S 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 S 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/
        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 S 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 installed, then 
     hot-insert the second adapter.

    -On the Combo adapter, to achieve 56Kbps 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 S Mobile Adapters must be initialized
     by running the CBCOMBO.EXE utility. 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 (see MODEM.HLP for more 
     information about CBCOMBO). The 32-bit ODI driver does not support modems.

     Laptops Running Windows NT 4.0
     ------------------------------
     On newer Toshiba models running Windows NT 4.0 and equipped with the Topic 
     97 or newer controller, the drivers will appear to install correctly. After the 
     first restart, however, the CardBus adapter will not function. To resolve 
     this condition, run TSETUP (the Toshiba setup utility) and change the 
     PC Card mode from Autodetect to 16-bit/Cardbus mode. Repeat the instal-
     lation process.

     Sometimes the default resources selected for NT do not work and the adapter
     will not function. If this happens, you will have to try others. Because of 
     the large number of laptops on the market, it is impossible to track the 
     precise resources for each one. In general, if the default resources don't 
     work, try these first, in the following order:
     
           IRQ:  11, 9, 5, 3
           I/O Memory:  d000, d400, 5b8000.

     When changing these resources, be sure to "cold boot" the laptop (turn it 
     completely off and back on with power switch).


     For other optional parameters, refer to the CB2HELP.HLP file on the 
     Intel CD.


6)  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.

     -Set the IRQ=11 in this model for proper operation in Windows NT 4.

     -The adapter will not function if your Tecra 550 is running the Toshiba 
      version of Windows 95. Upgrade to Windows 98 or Windows Me to solve
      this issue.


8)  MODEM INFORMATION
    =================

For AT commands and V.90 S registers, see the CB2HELP.HLP file on the Intel CD.

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 autodetect 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 autodetect. If host does not support 
                   v.90 autodetect 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.
