1)  CBEM and RBEM CHARACTERISTICS
    =============================
    This release of the Xircom CardBus Ethernet 10/100 + Modem 56 
    has the following characteristics:

    -CBEM provides Ethernet 10/100 and 56K modem performance in a 
     Type II CardBus PC Card.

    -RBEM provides Ethernet 10/100 and 56K modem performance in 
     Xircom's patented Integrated PC Card form factor. The RJ-45 and
     RJ-11 connectors are integrated in the RealPort Integrated PC
     Card.
    
    -10/100Mbps connectivity - Allows portable PCs equipped with a 
     CardBus slot to connect to 100Base-TX Ethernet networks to take 
     advantage of higher network bandwidth. See model descriptions 
     below for additional information.

    -The CardBus Ethernet 10/100 + Modem 56 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 100Mb networking. 
     
    -CBEM includes Xircom's second generation CardBus technology for 
     improved performance and power management. 
      
    -NWay auto-negotiation of 10 or 100Mbps 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 10Mbps (10Base-T) or 100Mbps 
     (100Base-TX) network segments. 

    -Utilizes 56K modem technology which 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. K56 
     technology 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 connection must support 56K 
     protocols (v.90/K56Flex) in order to achieve 56Kbps speeds. 

    -Support for using a second PC Card at the same time as the Xircom
     CardBus adapter in any version of Windows 95 OSR2 or later 
     (CBEM only). See machine specific notes for limitations.

    -Support for using a second PC Card at the same time as the Xircom
     CardBus adapter in Windows NT 4.0 (CBEM only).

    -Full suite of network driver support - Allows 10Mbps or 100Mbps 
     connection across a wide range of operating systems and networks. 
     Native 32-bit NDIS3 and NDIS4 driver support for Windows 95 OSR2 
     and Windows NT is included.

    -Includes Xircom's Battery Save (TM) technology. When the LAN 
     cable is disconnected from the adapter, the CBEM56G-100 
     automatically puts the LAN circuitry into a low power state. 
     When the LAN cable is reattached, it automatically powers 
     itself back up.

    -Advanced power management capabilities including Wake on LAN,
     Magic Packet, and support for the ACPI and CardBus Power 
     Management Specifications.  However, current operating systems lack 
     support for these features.  Support was not included in Windows 98
     Service Release 1, and is not expected in the initial release of
     Windows 2000 for either CardBus or PC Card (PCMCIA) adapters.  Xircom
     will provide updated drivers for Windows NT 5.0 when appropriate. 

    -Xircom software which enhances the ability of Windows 95 OSR2
     (950B) and later to support CardBus multifunction devices.

    -A Windows LAN diagnostic program.

    -A Windows Modem diagnostic program.

    -Windows 3.x installation program - Automatically configures both 
     PC and NOS setup directly from Windows versions 3.1 and 3.11.

    -SNMP network management agent included - Allows a portable PC to 
     be managed using SNMP-based network management software.

    -Models available:

     CBEM56G-100BTX    Supports both 10Base-T and 100Base-TX
                       with a single cable connector.
     RBEM56G-100BTX    Supports both 10Base-T and 100Base-TX
                       with an integrated RJ45 connector.

2)  WHAT'S NEW IN THE 2.55 SOFTWARE DRIVER RELEASE
    ==============================================
    
    -This release includes NDIS5 drivers compatible with Windows 98 and 
     Windows 2000.

    -Support has been added for O2Micro CardBus controllers in Windows 
     95 OSR2, Windows 98, and Windows NT 4.0.

    -Includes a fix for TCP/IP routing issues encountered when dialing into 
     a network normally accessed via a LAN.  This fix is provided by a new 
     keyword, DynamicLinkDetect.  See Section 5 below.

    -Includes a fix for throughput problems when network connections to 
     certain 10/100 switches are forced to 10Mbps.  This fix is provided by
     a new keyword, Auto Polarity.  See Section 5 below.

    -Improves support for direct connection to switches.  This support has
     been provided by a new keyword, Initialization Delay.  See Section 5
     below.

    -The Windows diagnostic program, Cbediag, has been enhanced.

    -The DOS NDIS2 driver, CBENDIS.exe, has improved performance with 
     Microsoft's DOS TCP/IP protocol.
    
    -Modem sound support is now provided on machines using Toshiba Topic97
     CardBus chipsets.
    
   
3)  USING CBEM IN WINDOWS 95
    ========================

    Using CBEM in Windows 95 versions 950 and 950A
    ----------------------------------------------
    The software in this release DOES NOT include support for Windows 
    95 versions 950 and 950A. A separate set of drivers specifically
    designed for use with Windows 950 and 950A is contained in the 
    download file "XBEM_1B.EXE, which is available from the "Hot Fixes" 
    section on the Xircom web site downloads page.

    Xircom Enhancements for Windows 95 OSR2 (950B)
    ----------------------------------------------
    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. CBEM includes software which enhances the 
    ability of Windows 95 OSR2 and later to support CardBus 
    multifunction devices. This support is implemented in the 
    NDIS3/NDIS4 drivers (CBE.SYS/CBEN4.SYS) and CBMFFIX.EXE.

    CBMFFIX.EXE is a Xircom program that helps Windows 95 OSR2 
    configure and use CBEM. It is launched automatically at the end of 
    the adapter's installation. The only indication that it has run 
    will be a dialog box telling the user to reboot to complete the 
    installation.

    On some machines, the program may detect that particular VxD 
    files from Microsoft are out of date.  Also, on some computers, it
    is possible that the files may not be reported as out-of-date, but 
    the adapter may not fully function after installation (for 
    example, the network side may function but the modem will not). 
    If the warning appears or such symptoms are encountered, it may 
    be necessary to obtain more recent versions of these files. The 
    specific files are:

      CBSS.VXD
      PCI.VXD
      PCCARD.VXD

    Microsoft has made available a program to automatically update 
    these files.  Before using this program, it is IMPORTANT TO BACK UP 
    YOUR CURRENT COPIES of these files (normally located in C:\windows\
    system)to another directory or to a floppy disk.  Microsoft's update
    program does not back up these files and cannot be reversed without
    manually locating and recopying these files to your machine.

    This update is available on the Microsoft Web site, currently at:
    http://www.microsoft.com/windows95/downloads/contents/wurecommended/
    s_wuservicepacks/pccard/default.asp?site=95.

    In order to function with Windows 95 OSR2, CBMFFIX places a 
    "forced configuration" onto the slot the card is inserted into.  
    Once this forced configuration is applied, no other card can be 
    inserted into that slot. However, the CBEM 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 CBMFFIX manually.  See the section below titled, 
    "Removing the Forced Configuration." 

    A log of the forced configuration data can be found in the 
    Windows\System directory in a file called CBMF.LOG. This log also
    contains the VXD file versions currently installed in the system.

    Removing the Forced Configuration
    ---------------------------------
    The forced configuration on the slot can be removed by running 
    CBMFFIX manually.  It can be found in the Xircom directory.  
    When double-clicked, the CBMFFIX displays a dialog box describing 
    the forced configuration information.  Pressing on the "Remove 
    Forced Configuration" button will restore the slot to normal.  
    This should be done before starting the upgrade. The card must be 
    inserted when CBMFFIX is launched.

    Known Limitations in Windows 95 OSR2
    ------------------------------------
    -Under Windows 95 OSR2, once CBEM is installed, no other card can 
     be inserted into the slot into which CBEM was installed. However, 
     CBEM can be removed and reinserted into the same slot while the 
     laptop is running. The adapter should not be installed into the 
     other slot.

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

    -There may be machine specific issues with certain computers.
     See Section 9, "Machine Specific Notes", for further information.
    
    Upgrading from Windows 95 OSR2 to Windows 98
    --------------------------------------------
    -If CBEM is installed in Windows 95 OSR2 and you are upgrading to 
     Windows 98, the CBMFFIX 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 95 OSR2 and Third Party Card Services
    ---------------------------------------------
    -Phoenix Card Manager for Windows 95 OSR2 
     The Phoenix software must be de-installed prior to running CBEM.
     See the Phoenix README file for instructions on de-installing the
     software. Xircom has tested with Phoenix version 4.00.48.   
     
    -SystemSoft CardWorks for Windows 95 OSR2
     This software is compatible with CBEM.  No special instructions
     are necessary. Xircom has tested with versions 5.32.11, 5.32.12 
     and 5.32.20.

    Windows NT 4.0 and Third Party Card Services
    --------------------------------------------
 
    The RealPort Ethernet CardBus + Modem 10/100 Adapter supports 
    manual installation under Microsoft Windows NT 4.0. Plug and Play 
    installation and hot swapping of CardBus adapters are not 
    directly supported by Windows NT, but may be supported through 
    third-party Card and Socket services software. 

    Some Windows NT 4.0 installations include third-party Card and 
    Socket Services software designed to improve PC Card installation 
    and to support hot swapping. In addition to its standard NDIS3 and 
    NDIS4 drivers, Xircom has also developed CBENT.SYS and 
    CBMODEMN.SYS to provide additional support for certain Card and 
    Socket Services software.

    With this release, the RealPort CardBus Ethernet + Modem Adapter 
    supports the following Windows NT 4.0 Card and Socket Services 
    software:

    -Card Executive for NT 4.0 from Phoenix Technologies:
     Support for Phoenix Card is provided by the special Card and 
     Socket Services driver CBENT.SYS and CBMODEMN.SYS. 

    -CardWare for Windows NT 4.0 from Award Software:
     Operation under Award CardWare for Windows NT is currently not
     supported. Please check the Xircom web site for any changes
     in status.

    -SystemSoft CardWizard:
     SystemSoft CardWizard v. 4.1 and above will provide basic support
     for CardBus Ethernet + Modem devices.  This version is required to 
     support CBEM. Full featured functionality (i.e., hot insertion, hot
     swap) has been implemented in CardWizard v. 5.0.  This version is 
     recommended for use with CBEM.  

    -PC Card Controller for NT from Softex Incorporated:
     Softex PC Card Controller for NT provides functionality 
     similar to Phoenix CardExecutive. If using Softex, follow
     the instructions for Phoenix CardExecutive described below. 

     Drivers available:
     The following drivers for Windows NT 4.0 can be found on the Xircom 
     CD-ROM:
      
       CBE.SYS - NDIS3 driver
       CBENT.SYS - Card and Socket Services driver
       CBEN4.SYS - NDIS4 driver
       CBMODEM.SYS - Modem enabler for Windows NT 4.0
       CBMODEMN.SYS - Card and Socket Services Modem enabler for 
       Windows NT 4.0     

     Which Driver to Use

     -CBE.SYS	
      For use under NT 3.51 and 4.0 without Card and Socket Services, 
      and for use under NT 4.0 with SystemSoft CardWizard for NT 4.0.

     -CBENT.SYS, CBMODEMN.SYS
      For use under NT 4.0 with Phoenix CardExecutive and Softex PC 
      Card Controller for NT.

     Installation under NT 4.0 Using Card and Socket Services

     1. Insert the RealPort CardBus Ethernet + Modem Adapter into the 
        CardBus PC Card slot.
     2. Once the Card Services software has detected the adapter, 
        follow the onscreen installation instructions for your Card 
        and Socket Services software. Use of default resource settings
        is recommended.
     3. If the Card Services software includes a driver for the Xircom 
        CardBus Ethernet Adapter, install that driver. Otherwise, 
        follow the guidelines below:
     
        -SystemSoft CardWizard Card Services software will display a 
         CardWizard icon on the task bar when you insert the RealPort 
         CardBus Ethernet + Modem adapter. Use the drivers located in 
         the root of the Xircom Windows 95, 98, and NT installation 
         disk. 
        
        -Phoenix CardExecutive and Softex PC Card Controller use the 
         drivers located in the \CBENT sub-directory of the Xircom 
         CD-ROM.  To assure that the correct driver is installed, it is 
         important that the Xircom driver CD or floppy disk NOT be inserted
         when the card is first inserted into the laptop.  Insert the card,
         and card services will search for a driver automatically.  When it
         fails to find the Xircom driver, it will next prompt for a driver
         disk and allow a path to be entered.  Insert the Xircom Driver 
         CD, and enter the path in the space provided.  For example, if
         your CD-ROM drive letter is "D", you would enter D:\CBENT\.

        -Award CardWare is not supported at this time, as described 
         above.

    New Features:
    -------------

    -TCP/IP Routing:

     This release contains a resolution for TCP/IP problems that occur
     when the same network is accessed via a LAN connection and then
     subsequently via a remote dial-up connection in Windows 95/98. 
     Typically, when the computer is connected to the network via the
     LAN, routing tables are constructed that direct packets intended
     for the network to the LAN interface. If the computer is then used
     remotely and an attempt is made to connect to the same network via
     dial-up networking, these packets may not be routed to the dial-up
     interface because the presence of the active LAN interface 
     results in the system's continuing to route packets to it instead.
     In such instances, the simplest solution is to remove the LAN 
     interface from the computer. However, in the case of a multi-
     function adapter, this solution cannot be used.

     The drivers included with this release now support a new 
     configuration keyword named "DynamicLinkDetect" to overcome this
     difficulty. The value of this keyword (ON or OFF) can be set by 
     going to Control Panel/Network/Network of Xircom.../Properties
     /Advanced. The default value is ON. The activity governed by this
     keyword operates as follows:

     ON -  The Ethernet interface is always active once the adapter is 
           initialized by the driver. An Ethernet cable need not be 
           connected to the port at boot time for the network side of 
           the adapter to initialize. If the cable is plugged in 
           later, or unplugged and then re-connected, the adapter will 
           dynamically detect the presence of the link and connect to 
           the LAN. This is the setting recommended unless the 
           symptoms described above are encountered.

     OFF - The Ethernet interface will only be initialized by the 
	   driver if an active connection to the network is present at
           boot time. If the presence of an active link is not 
           detected, the Ethernet portion of the card will shut down. 
           As a result the OS will "assume" that the interface is not 
           present, and no packets will be routed to it.  As a result,
           the IP routing trouble discussed previously should be 
           eliminated.

    -Auto Polarity Correction:

     Certain 10/100 switches (generally those using Broadcom transceivers) 
     implement automatic correction for polarity reversed cables that is
     not completely compatible with the same correction provided by the 
     CBEM/RBEM.  If the network speed is forced to 10Mbps, severe throughput
     problems may be experienced.  To resolve this problem, a new 
     Auto Polarity keyword in the adapter's advanced properties has been 
     added.  If needed, the default setting of ON (meaning that the card
     will compensate for reversed cables) can be set to OFF to disable 
     polarity correction.  This will restore normal throughput.

    -Initialization Delay

     Certain switches and routers are unable to immediately forward network
     traffic when a network adapter first establishes link to one of their
     ports due to initialization delays (generally while routing tables are
     being updated).  This problem is most commonly seen when the network 
     adapter is connected directly to ports on the switch.  This may cause
     an initial DHCP request to fail or prevent login to a server.  The 
     adapter by default (when used under some operating systems) will have
     almost no delay between link and the initial network request.  A new
     keyword, Initialization Delay, has been added to the adapter's advanced
     properties which will prevent forwarding of network requests for a 
     user-selectable period of time.  Delays can be added ranging from one
     to sixty seconds.  In most cases adding a delay in the one to three 
     second range will be sufficient to resolve the problem.     
     
     
    Com Port Assignment in Windows 95 OSR2 and 98
    ---------------------------------------------

    -Windows 95/98 will assign the modem in CBEM/RBEM to Com5. Windows
     applications supporting TAPI support the use of Com5. If you
     have an application which does not support the use of Com5, the 
     Xircom Com Select Utility can be used to change the com port 
     assignment in Windows 95/98. It will allow you to select an 
     unassigned com port and assign it to CBEM/RBEM.  The Com Select 
     Utility is installed to the Xircom program group when the setup
     program is run.
    -See Machine Specific Notes in Section 9 for additional 
     information on using the Com Select Utility with specific 
     machines.
    -The Com Select Utility operates only under Windows 95 and Windows
     98.  It does not operate under Windows NT.  However, it does get
     copied to the program group in Windows NT.  If launched, the 
     program will report that it does not work under Windows NT.

    V.90 configuration and use information - S109 register
    ------------------------------------------------------

    Current released firmware for Xircom 56K modem products now 
    includes support for the v.90 56K modem standard. This firmware 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. At this 
    point in time many v.90 hosts do not yet support autodetect. In 
    such cases it will be necessary to issue an ATS109=2 command to 
    the modem in order to force a v.90 connection.
 
    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/NT dial up networking, go to
     Control Panel\Modems. Highlight the Xircom modem and click 
     Properties. Click Connection\Advanced. Enter S109=n (where n is
     the value desired) in the Extra Settings box.

    Known Limitations    
    -----------------

    -Support for the Ricoh and O2Micro chipsets is not currently 
     implemented under NT 4.0 when third-party Card and Socket Services
     are installed, or under Windows 2000.

    -Under Windows 95 OSR2, once CBEM is installed, no other card can 
     be inserted into the slot into which CBEM was installed. However, 
     CBEM can be removed and reinserted into the same slot while the 
     laptop is running. The adapter should not be installed into the 
     other slot.
 
    -Windows 95 may fail to load CBEM when Windows 95 comes out of 
     Suspend/Resume.  To make CBEM load in this situation, click on
     the PC Card icon in the System Tray (or in Control Panel), click
     Stop, eject CBEM and then re-insert it. CBEM will now load.
  
    -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 Xircom CardBus Ethernet 10/100 Adapter + Modem 56 is designed 
     to connect to a 100Base-TX network. It does not support 100VG-
     AnyLAN or 100BaseT4 networks.     

    -When running the LAN Requester install, the CBENDIS.EXE file does 
     not get copied to the NET directory. The file needs to be 
     manually copied from the CD-ROM to the NET directory on the users 
     hard drive.

    -When running the Lantastic 7.0 install, the CBENDIS.EXE file does 
     not get copied to the LANTASTI directory. The file needs to be 
     manually copied from the CD-ROM to the LANTASTI directory on the 
     users hard drive.

    -For Toshiba Tecras, using the 16-bit ODI driver with the NDIS3
     mapper in Windows for Workgroups is not currently supported.

    -If the CBEM does not load in the top PC Card slot on Toshiba 
     Tecras and Porteges, there are two remedies:
     1.  Try using the adapter in the lower slot.
     2.  Disable support for the infrared device by commenting out 
         (put a semi-colon ";" in front of) the following line in the 
         Windows SYSTEM.INI file:

           device=C:\TRANXIT\pumafir.386
 
    -The 32-bit ODI driver (CBE.LAN) supports promiscuous mode. 
     There is one limitation in its support. Fragment errors are 
     captured, but they are classified, counted and reported as 
     undersized errors. Therefore, the total count for undersized
     errors includes the total of undersized and fragment errors.

    -If you are attempting to use CBEM in a port replicator or 
     docking station, are using Windows 95 and are having problems, 
     and you have confirmed that your laptop has the latest BIOS and that
     the latest manufacturer's patches and utility software have been 
     installed, there are three additional alternatives: 
     1. Put the card in the notebook rather than the replicator/
        docking station, 
     2. Manually load the CBEM driver,
     3. Windows 98 appears to better support this environment 
        than Windows 95.

    -When using the Packet Driver with the Intel 10/100 Stackable 
     hub, network connections may be lost at 10Mbps.  

    -When attempting to use CBEM with a second 16-bit adapter 
     (e.g. modems, flash cards, ATA cards) in the other 
     slot, it may be necessary to boot up with the CBEM first then 
     hot-insert the second adapter.

    -In order to achieve 56Kbps connects (v.90 or K56flex), there can 
     be only one digital to analog conversion between the connecting 
     modems. Also, the modems at both ends of the call must be 56K 
     compatible to achieve 56K speeds; otherwise a standard V.34 
     connection (maximum 33.6Kpbs) will be negotiated. Current FCC 
     regulations limit download speeds of the modem to 53Kbps.

    Modem Script Files
    ------------------
    -Modem script files for popular applications can be found in 
     the \SCRIPTS directory on the CD-ROM.

6)  INSTALLING THE NDIS4 DRIVER IN WINDOWS 95 OSR2 AND NT 4.0
    =========================================================
    
    Using the NDIS4 Driver
    ----------------------
    -This release of CBEM includes both an NDIS3 and NDIS4 driver. 
     By default, the NDIS3 driver is installed. If you would like to 
     use the NDIS4 driver rather than the NDIS3 driver, please 
     follow these instructions:

     1. When prompted by the operating system for the disk with the 
        CBEM driver, insert the CD-ROM. 
     2. Browse to the \NDIS4 directory on the disk and select 
        CBEN4.SYS. 
     3. Complete the installation by following the onscreen 
        instructions.  
    

7)  Using the CBEM/RBEM in Windows 2000 Beta 3
    ==========================================

    Windows 2000 Beta 3 contains built-in drivers for the Xircom RBEM and
    CBEM, as well as many other Xircom Cards.  The built-in drivers are 
    functional but lack the new features of this release.  To update the
    Windows 2000 driver do the following:

    1.  You will need to have the Xircom RBEM/CBEM installed and inserted in
        the laptop to proceed.  Go to Start/Settings/Control Panel, double
        click on Network and Dial-up Connections, and double click on Local
        Area Connection.  Select Properties.
  
    2.  Click the Configure button on the top of the Local Area Connection
        Properties screen, just under the "Connect using:" listing for the 
        Xircom CardBus Ethernet 100 + Modem 56.  Next select the Driver
        tab, and click the Update Driver button.  This starts the Upgrade
        Device Driver Wizard.  Click Next.  On the next screen select 
        "Search for a Suitable driver for my device (recommended)".  Click 
        Next.  On the Locate Driver Files screen, select "Specify a 
        location", and click Next.  Enter the path to the NDIS5 
        subdirectory of the Xircom driver CD or directory where you 
        extracted the files.  For example, if you were installing from the 
        CD and your CD-ROM drive was drive D, you would enter "D:\NDIS5".

    3.  The Wizard will announce that it has found a driver that is a closer
        match for this device than your current driver.  Click Next.  
        You will then be notified that Microsoft has not digitally signed 
        the software, and asked if you want to continue the installation.
        Click Yes.  The updated drivers will then be copied to your 
        computer.  Click "Finish", and then click "Close".  Click "OK" to
        close the Local Area Connection Properties box.  Reboot the machine
        to utilize the new driver.  The new driver settings may be accessed
        by following step 1 above, clicking the Configure button, and 
        selecting the Advanced tab. 
        
8)  CardBus Equipped Portable Computers
    ===================================

    CBEM56G-100 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, visit the Xircom web site or contact the manufacturer 
    of your laptop.

10)  CREATING A DISK INSTALL
     =======================
    -If you need a diskette version of the CBEM software for 
     installation on a system without a CD-ROM, the CD-ROM includes 
     two directories, DISK1 and DISK2 which contain files that can be 
     copied to diskettes. This can be done manually or by running 
     MAKEDISK.BAT. DISK1 includes the files necessary for DOS and 
     Windows 3.X. DISK2 includes the files necessary for Windows 95, 
     98 and NT 4.0. (NDIS3 drivers only). 
  
11) SNMP AGENT
    ==========

    Xircom provides SNMP support for the CBEM. 

    To use the agent under DOS, follow these instructions:
    ------------------------------------------------------

    1.  Copy all of the SNMP directory on the CD-ROM to your hard disk
        drive, typically to the \NWCLIENT directory.

    2.  Edit the SNMP.CFG file and add the correct IP address and
        other configuration information. Contact your system
        administrator if necessary.
  
    3.  Edit the NET.CFG file (typically in \NWCLIENT) to include:
        Frame Ethernet_II

    4.  After the LAN driver is loaded, load the SNMP driver, 
        XAGENT_O.EXE, by changing to the directory where it exists, 
        typing XAGENT_O and pressing ENTER. Alternatively, add the 
        following lines to AUTOEXEC.BAT:

          CD\NWCLIENT
          XAGENT_O

        Note: You must change to the directory (NWCLIENT) before 
        loading the driver, otherwise it won't load properly.
    
    To use the agent under Windows 95, follow these instructions:
    ------------------------------------------------------------- 

    1. First install the Microsoft SNMP agent:

    For Win95:
    Control panel ->  Network ->  Add ->  Service ->
    either:
    Microsoft -> SNMP Agent
    or:

Download Driver Pack

How To Update Drivers Manually

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.
