=======================================================
Downloading the QFE Patch
-------------------------

In some computers running Windows 95 (OSR 2), the
computer comes up on reboot with the card not working.
The card is accessed and the PCI devices are found,
but the card slot is powered down.  If you remove the
card and reinsert it, power is applied to the slot and
Windows correctly allocates resources.

In order to support Multifunction CardBus cards,
Windows 95 OSR 2.x needs to have the following files
updated to compatible versions:

CBSS.VXD
PCCARD.VXD
PCI.VXD

This update is not required for other operating
systems.  

3Com's setup utility (SETUP.EXE) will check your
system and tell you if you require the Microsoft
update utility.

Before updating these files, copy them to another
location or rename them so that you can restore them
again, if necessary.

These files, supported and distributed by Microsoft,
could not be shipped with the LAN+Modem card.  3Com,
however, provides links to the correct Microsoft Web
page at:

http://support.3com.com/infodeli/tools/nic/micro.htm

You will need to reboot your computer after installing
the upgrade.

If problems persist after installing the update, you
may have to uninstall and reinstall the LAN+Modem card.

============================================================
DynamicAccess Software
----------------------

DynamicAccess software support is available for the
LAN+Modem card. DynamicAccess software adds
intelligence to the Network Interface by integrating
the following features:

 - Distributed RMON (dRMON) — Enables full RMON
   reporting on all network segments, including
   switched networks, without the need to place
   dedicated RMON probes throughout the network.

 - Traffic prioritization — Ensures that
   business-critical and delay-sensitive traffic (such
   as multimedia applications) has priority over
   normal data.

 - Fast IP — Eliminates router bottlenecks and
   improves performance in switched networks.

 - Efficient multicast control — Prevents flooding of
   switched networks by multicast applications such as
   video training, stock quotes, or online news. 

The DynamicAccess software can be installed under
Windows 95, Windows 98, or Windows NT 4.0. The Dynamic
Access software is supplied on the Installation CD.
The following procedure assumes that the CD-ROM drive
is Drive D and that the Installation CD is in the drive.
Note: If you are installing DynamicAccess under Windows 98
Service Edition 1 (build 2222), do not install from this CD
ROM.  Download Dynamic Access 1.5.4b from the 3Com web site
and install that version.

1. From the Start/Run menu, run d:\da\da15swy

   This self-extracting archive will create a folder
   called c:\3comda15.

2. Change to the \3comda15\da15sw subdirectory. Type:

Problems and Solutions
----------------------

This section identifies known problems with LAN+Modem
card installation and operation. Topics include:

 - General Problems
 - Problems Related to Windows 95 OSR 2
 - Problems Related to Windows 98
 - Problems Related to Windows NT 4.0
 - Problems Related to Specific Hardware Platforms

=======================================================
General Problems
----------------

Problem: System hangs when card is in docking station

         Some laptop docking stations do not properly
         manage resources for the LAN+Modem card. If
         you notice this problem, we recommend that
         you install the LAN+Modem card only in the
         computer's main card slots.


Problem: Network performance is slow; or,
         computer not connecting to network.

         If the network interface is set to autosense
         with auto polarity disabled and the cable is
         connected to a port set for 10Mbps/Full,
         performance may be affected. If switch is
         configured for 10Mbps/Full and the card for
         Auto, a mismatch of duplex mode may result.

         If you are connecting to a dual-speed 10/100
         hub or to a switch forced to 10Mbps speed,
         make sure the settings on the card match
         those on the switch.

         If not, disable autopolarity and set the
         speed and duplex to match the port.
         To disable autopolarity:

          1. Open Control Panel/Network.
          2. Click Adapters. 
          3. Select Properties and disable Auto Polarity.
          4. Reboot

          You can manually set network speed and polarity
          for all supported environments.

Problem: Unable to ping between two installed LAN cards

         This could be a problem with how the IP
         addresses are bound. Bind one card to a
         static IP address. For the other, set
         networking to specify the IP address
         automatically.

Problem: Wake-up-on-ring feature enabled, card will
         not wake up

         Suspend/Wakeup-On-Ring is not currently
         supported by Windows. Hence, in suspend mode,
         your computer turns off the power to the
         card, which means that there is no way for it
         to detect the ring.

Problem: System refuses to enter suspend mode while a
         communications application is running

         The LAN+Modem card does not support forcing
         the system into suspend mode while a
         communication application (such as
         HyperTerminal) is running. Windows environments
         reject suspend-mode requests in such instances.

         After the suspend-mode failure, the LAN
         interface may no longer show up in the system
         as a valid device. If this happens, try one
         of the following:

         - Close all programs and log in as a different
           user.
         - Remove the card from the computer, reinsert
           it in the same slot, and run Suspend/Resume
           again.

Problem: Could not install the card because system could
         not find a valid .INF file; or,
         card is not recognized by system.

         This is a BIOS problem. Contact your computer
         vendor for information on obtaining and
         installing the latest BIOS version for your
         computer. 

=======================================================
Problems Related to Windows 95 (OSR 2)
--------------------------------------

Problem: An option to select NDIS5 appears in Windows
         95 OSR 2 driver options

         Although this prompt may appear under Windows
         95, this operating system supports only NDIS 4.

Problem: Modem does not give a sound

         With the default audio settings for Windows
         95, you may not hear the sound from the modem
         when you dial out. To enable the sound,
         complete the following procedure:

      1. Locate the speaker icon in the system tray.

         If there is no speaker icon in the system
         tray, open the Control Panel and double-click
         Multimedia.  On the Audio page, make sure
         Show volume control on the task bar is checked

      2. Double click the speaker icon in the system
         tray.

      3. When the Master Out window opens, select
         Options.

      4. Choose Properties and make sure the Mono In
         box is checked. Click OK.

      5. When the Master Out window is redisplayed,
         check Mono In Balance. Ensure that the mute
         box is unchecked.

         If the modem still does not make a sound,
         you may need to update your computer's BIOS.

Problem: Failure to install two LAN+Modem cards

         The modem driver only supports one modem in
         Windows 95 environments. For this reason,
         dual installations are not supported.
         However, you can disable one modem
         installation and operate with one modem and
         two LAN connections. For technical
         information, see Microsoft Limitation Article
         Q184191 on he Microsoft on-line support Web
         site.


=======================================================
Problems Related to Windows 98
------------------------------

Problem: Card fails to install.

         This problem has been observed on several
         hardware platforms and usually indicates that
         the computer's BIOS is not properly
         supporting Windows 98. Upgrade to a current
         BIOS that supports Windows 98.  Contact your
         computer manufacturer for details.
    
Problem: Problems with IntraNetware Client 2.2

         Novell IntraNetware client version 2.2 does
         not support Windows 98. If you try the
         LAN+Modem card with this network operating
         system, you may experience problems.
         Obtain and install Novell IntraNetware client
         version 3.1 or later.

Problem: Cannot install two Winmodems

         This is a Winmodem limitation. Only one
         installed modem will function under Windows
         98.  However, both LAN interfaces should
         behave normally.

         If you must have two modems installed, you
         can run a controller-based modem
         simultaneously with a Winmodem.

Problem: Modem does not give a sound

         With the default audio settings for Windows
         98, you may not hear the sound from the modem
         when you dial out. To enable the sound,
         complete the following procedure:

      1. Locate the speaker icon in the system tray.

         If there is no speaker icon in the system
         tray, open the Control Panel and double-click
         Multimedia.  On the Audio page, make sure
         Show volume control on the task bar is checked

      2. Double click the speaker icon in the system
         tray.

      3. When the Master Out window opens, select
         Options.

      4. Choose Properties and make sure the Mono In
         box is checked. Click OK.

      5. When the Master Out window is redisplayed,
         check Mono In Balance. Ensure that the mute
         box is unchecked.

         If the modem still does not make a sound,
         you may need to update your computer's BIOS.


=======================================================
Problems Related to Windows NT 4.0
----------------------------------

Problem: Using cellular connect, some files do not transfer.

         The card does not support cellular connect with NT4
         running Softex card and socket services. For cellular 
         connect, use the following initialization procedure.

         The default modem setting is AT&F.
         1. Set control call as follows:
            Motorola cellular phones -- AT~C0
            Nokia cellular phones    -- AT~C1

         2. Enter the following initialization string:
            AT+MS=v34,0,0,7200,0,7200
            ATS53=85
            ATS54=0

Problem: Computer not connecting to network.

         The most common problems under NT 4.0
         occur because system resources are
         not set correctly.

         If you are installing the LAN+Modem card
         using the point-enabler procedure, refer
         to the following table for examples of what
         resources to select.

         Remember that you can always use the
         Windows NT Diagnostics Resource tab to
         determine which resources are free.

         For a more detailed list of what resources to
         try for specific notebook computer models, see
         file NTconfig.txt.

Problem: Suspend/Resume and hot-swap problems

         This class of NT problems may be due to
         limitations in the support for dual-function
         cards under various card and socket services.
         Remove the card wizard or card and socket
         services software and reinstall the card
         using the point-enabler installation procedure
         described in the User Guide.  

         This problem may be fixed in later versions
         of the software.  Contact your software
         manufuacturer for information on updates.

Problem: Card Slots disabled in NT 4.0 after card
         installation

         it is necessary to enable the PCMCIA device
         in Windows NT 4.0. To do this, click My
         Computer/Control Panel/Devices.  Scroll down
         to the PCMCIA.  Click Startup.  Change the
         selection to BOOT and click OK.  You will
         need to restart the computer.

         On some computers, you will have to set the
         BIOS for CardBus support. If you are not
         sure how to do this for your computer,
         contact your computer manufacturer for
         the correct procedure.

Problem: Network Setup Wizard busy or not responding. 

         This has been observed on some systems
         running SystemSoft Card and Socket Services
         version 4.10.13.

         The installation seems to proceed normally.
         At the message: "Windows NT is now ready to
         start the Network so that you can complete
         the installation of Networking. Click Next to
         start the Network."

         Turn off the computer and restart it. This
         should restore the card to normal operation.

=======================================================
Problems Related to Specific Hardware Platforms
-----------------------------------------------

Fujitsu Lifebook 585TX
Problem: While using the LAN and modem functions at the
         same time, the computer fails to respond.

         Simultaneous LAN and modem operation is not
         supported on this computer.

Texas Instruments Extensa 390
Problem: System will not detect card.

         The LAN+Modem card is not supported on this
         computer. 

Toshiba (all models)
Problem: Card does not respond when configured with
         default resources

         This problems applies to systems running
         Service Pack 3 under Windows NT 4.0.  When
         the card is set up using the default
         settings, the system may not respond. Toshiba
         systems require IRQ 11 for the LAN+Modem
         card.  Changing the interrupt from 10 to 11
         solves the problem.

         Refer to NTCONFIGS.TXT
On the Toshiba Satellite 4000 CDT, IRQ 15
         is already in use (ATAPI). On this platform,
         use the Windows NT Diagnostics Resource tab
         to determine which resources are free. You
         can, for example, create a COM8 at IO 3F8
         with IRQ 13.
