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 and 
Windows NT 4.0 is included. An NDIS5 driver is included for use 
with Windows 98 and Windows 2000.

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 2000 when appropriate. 

Xircom software is included that enhances the ability of Windows 95 
OSR2 (950B) and later to support CardBus multifunction devices.  
Other Xircom software utilities provided in this release include:

A Windows LAN diagnostic program.

A Windows Modem diagnostic program.

A Windows Modem informational and management program.

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.

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/wurecommend 
  ed/ 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.exe manually.  It can be found in the Windows\System 
directory.  When double-clicked, the CBMFFIX displays a dialog box 
describing the forced configuration information.  Each CardBus 
socket is displayed along with its Status (either Plug&Play or 
Locked), and whether a Xircom card is currently inserted.  Forced 
configurations may be removed either from each socket individually 
(by selecting the individual locked socket and clicking on the 
Remove Lock button) or all at once with the Remove All button.  
This should be done before performing an upgrade from 95OSR2 to 
Windows 98 or Windows 2000. 


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, or a forced configuration will be applied to both slots, and 
other PC Cards may not be usable.  If this happens, see the section 
above titled "Removing the Forced Configuration" for instructions 
on how to remove it.

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
=========================

Note:  With this release Xircom has implemented automatic driver 
selection and installation for all supported Windows versions, 
including Windows NT 4.0 with supported versions of third- party 
card services.  No special installation procedures are now 
required, nor do special purpose drivers need to be selected for NT 
card services.  For all installations under Windows 95 OSR2 (or 
better), Windows 98, Windows NT 4.0, Windows Millennium, and 
Windows 2000, the drivers may be found by pointing to the root of 
the CD-ROM, or of floppy diskette 2.    

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 Phoenix and Softex 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 Services are provided by the special Card 
and Socket Services drivers CBENT.SYS and CBMODEMN.SYS.  These will 
be automatically selected and installed if your computer uses Card 
Executive.  

1. Boot your machine.  Insert the CardBus Ethernet 10/100+Modem 56 
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.  Insert the Xircom driver CD-ROM or floppy 
diskette 2, and select "Install the driver that was provided with 
the PC Card."  Phoenix Card services will automatically search the 
floppy drive for drivers, but if you are installing from CD-ROM you 
may need to direct the install to the root of the CD.

3.  Working resources will be automatically determined by the 
install.  Accept them, and after a short delay card services will 
announce that the card is configured and available for use.

After the network drivers are installed, you will need 
to install the modem.  Restart your computer, and proceed as 
follows:

MODEM SETUP

1. After the computer has restarted, double-click the Modems icon 
in Control Panel.

2. At the Install New Modem screen, verify that the "Don't detect 
my modem; I will select it from a list" option is NOT checked and 
then click Next.

3. Windows NT queries the COM ports to determine if a modem is 
present.

4. Once NT detects the modem, the Install New Modem window 
appears displaying the type of modem found. In most cases, a 
Standard Modem is displayed.

5. Click Change. This action brings up the dialog box containing 
a list of Manufacturers and modem models. Click the Have Disk 
button. 

6. Enter the path to the Xircom files in the "Copy 
manufacturer's files from:" box. Click OK.

7. Verify that the Xircom CardBus Modem 56 is selected (DO NOT 
select the Xircom CardBus Modem 56 - Manual Load), then click OK.

and on-line documentation. 

13. Restart the computer so that the Xircom CountrySelect utility 
Runs. Select the appropriate country, save the settings and then 
click Exit. 

14. The Xircom Registration utility runs automatically after the 
Xircom CountrySelect software closes. Complete the registration 
form and send it to Xircom.  

PC Card Controller for NT from Softex Incorporated
--------------------------------------------------

Softex PC Card Controller for NT provides functionality similar to 
Phoenix CardExecutive. The correct drivers will be automatically 
selected and installed just as with CardExecutive.
 
CardWare for Windows NT 4.0 from Award Software
-----------------------------------------------

With versions of Award CardWare prior to 6.0.015 the Xircom driver 
will co-exist with Award's software but full functionality 
including hot swapping and hot insertion are not supported.  Full 
support including hot insertion and hot swapping are available with 
Award version 6.0.015 or later.

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, 
hotswap) has been implemented in CardWizard v. 5.0 and above.  
These versions are recommended for use with CBEM/RBEM. 

Installation under NT 4.0 Using SystemSoft Card and Socket 
Services:

1. Insert the RealPort CardBus Ethernet 10/100+Modem 56 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

New Features
============  

Automatic Windows Driver Selection and Installation
---------------------------------------------------

With this release Xircom has implemented automatic driver selection 
and installation for all supported Windows versions, including 
Windows NT 4.0 with supported versions of third-party card 
services.  No special installation procedures are now required, nor 
do special purpose drivers need to be selected for NT card 
services.  For all installations under Windows 95 OSR2 (or better), 
Windows 98 and 98SE, Windows NT 4.0, Windows Millennium, and 
Windows 2000, the drivers may be found by pointing to the root of 
the CD-ROM, or of floppy diskette 2.

                       
NDIS Driver Selection 
---------------------

This driver release now supports NDIS version selection for 
installs under Windows 9x, Windows NT 4.0, and Windows 2000.  For 
installs under Windows 9X, Windows NT 4.0, or Windows 2000, direct 
the install to the root of the CD (or of floppy disk 2) when the 
drivers are requested.

The network property page tab of the CBE/RBE has a new entry
"NdisVersion".  This entry contains the following:

Under

Windows 95OSR2: AutoSelect, NDIS3, NDIS4
Windows 98: 	AutoSelect, NDIS3, NDIS4, NDIS5
Windows 98SE: 	AutoSelect, NDIS3, NDIS4, NDIS5 
Windows NT4.0:  NDIS4 (default), NDIS3
Windows 2000:   "NdisVersion" does not exist and NDIS5 is the
                default driver. The NDIS Switcher is not used
                with Windows 2000.

AutoSelect (the default) will choose the highest NDIS version
supported by the OS.  The user can also manually switch between the
different supported versions of NDIS by going to NdisVersion in the
network properties of the adapter and selecting the desired driver.
Only drivers supported by the particular OS will be shown.

                
Improved Windows NT Installation 
--------------------------------

This release contains additional improvements for Windows NT 4.0 
that allow faster and easier manual (without card services) 
installations.  NT 4.0 alone provides no Plug&Play functionality, 
and gives little guidance in choosing acceptable resources.  The 
drivers in this release incorporate a resource scan that checks for 
resources already in use, and excludes those resources from the 
range shown in the adapter's configuration settings .  The initial 
default resources are no longer fixed, but are automatically set to 
resources determined to be available.  This greatly increases the 
chances that the adapter will function without further 
configuration changes.


NWay auto negotiation changes
-----------------------------

This release features a new implementation of NWay auto 
negotiation.  NWay is an industry-standard way for hubs, switches, 
and network cards to automatically determine each other's speed and 
duplex capabilities, and set each device's communication settings 
to the fastest mutually supported speed.  In earlier driver 
releases, as is normal in the industry, forcing the speed and 
duplex settings completely disables auto negotiation.  This was 
done because the forced settings were meant as a backup when 
connecting to older non-NWay devices.  When forced settings are 
used when connecting to other NWay devices, (perhaps to restrict 
bandwidth), the other device must also have it's speed and duplex 
settings forced as it cannot reliably sense the settings without 
negotiation messages.  

In this driver release NWay negotiation is active by default 
whether or not the settings are forced.  Other NWay devices, even 
in auto mode, will be able to determine your card's settings and 
negotiate to match them.  In cases where the standard behavior is 
not successful, the negotiation messages can be disabled.  Some 
early NWay devices and non-NWay devices do not always respond well 
to negotiation signals.

A new keyword, Line Negotiation, can eliminate the negotiation 
messages when the settings are forced.  The forced + no negotiation 
messages settings also allow immediate link if required by any 
special circumstances.  

The keywords and their settings are as follows:

Keyword              Settings             Behavior 
-------              --------             ---------

Line Configuration   Auto (default)       Full NWay negotiation, 
                                          Line Negotiation keyword
                                          ignored.
                     100 Mbps/Full Duplex
                     100 Mbps/Half Duplex
                     10  Mbps/Full Duplex
                     10  Mbps/Half Duplex

Line Negotiation     On (default)         NWay messaging sent in 
                                          all modes 

		     Off                  NWay messaging disabled 
		                          if Line Configuration 
		                          forced		  


RealView Utility
----------------

This release includes Xircom's RealView modem and network 
informational and diagnostic utility, provided in the RealView 
directory of the Driver CD-ROM.  There is a separate Setup program 
in the RealView directory that may be used to install RealView if 
desired.  RealView contains extensive context-sensitive help that 
is available from within the program.

NOTE:  The version of RealView in this release does not have 
support for the card uninstaller feature when used with the 
CBEM/RBEM cards, and this feature has been turned off by default.  
Later versions of RealView will provide this functionality. 


Additional Information
======================

TCP/IP Routing- Dynamic Link Detect Keyword
-------------------------------------------

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 driver 
initializes the adapter. 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 driver will only initialize the Ethernet interface 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.

                    
Modem Script Files 
------------------

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

Support for O2Micro chipsets under NT 4.0 requires that the laptop 
BIOS initialize the CardBus controller as a PCI device and set up 
PCI routing.   

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 reinitialize the CBEM when Windows 95 comes 
out of Suspend/Resume.  To make the CBEM restart 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+Modem 56 Adapter 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 user’s 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.

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 fragments errors.

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.

  
6) Using the CBEM/RBEM in Windows 2000     
======================================

Windows 2000 contains built-in drivers for the Xircom CBEM and 
RBEM, 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 CBEM/RBEM 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 Adapter 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 
Xircom driver CD, diskette, 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:\".

3.  The Wizard will announce that it has a suitable driver already 
installed, and that it has also found other drivers suitable for 
this device.  Select the "Install one of the other drivers" check 
box and click Next.  You will then see a screen showing both the 
Microsoft-provided driver, and the new Xircom driver (identified as 
Xircom Ethernet Adapter 100 + Modem 56, and with a path listed to 
your driver CD or diskette).  Select the Xircom driver, and click 
Next.

4.  You will then may 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.  By following step 1 above, clicking the 
Configure button, and selecting the Advanced tab you may now access 
the new driver settings.

                           
7) MACHINE SPECIFIC NOTES
========================= 

Visit the Xircom web site for the latest machine specific 
information.

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

Machines using O2Micro CardBus chipsets  
---------------------------------------

O2 Micro controllers cannot be used with CardBus adapters under 
Windows NT unless the BIOS of the laptop initializes the 
controllers as PCI devices and sets up PCI routing.  Several 
manufacturers have released or are in the process of releasing BIOS 
updates to provide compatibility with NT 4.0. If you desire to run 
NT on one of these laptops, contact the manufacturer for more 
information.

Compaq Armada 1580
------------------

If using the DOS 16-bit drivers, it is necessary to insert the CBEM 
in the bottom slot.  

Dell Inspiron 3200
------------------

The Com Select Utility does not change the com port assignment on 
this machine. 

Hitachi VisionBook Plus 5000
---------------------------- 

The Com Select Utility reports Com3 as being available even though 
it is used by the internal modem.  After reboot, the internal modem 
will be moved to Com5 and CBEM will be assigned to Com3.

HP 4150
-------

In some environments the 4150 can experience video corruption and 
network problems when used with CardBus adapters.  A BIOS update 
which resolves these issues is available to affected customers by 
calling HP Customer Support.

IBM ThinkPad 760ED 
------------------ 

If using the 32-bit ODI client (CBE.LAN), interrupt 9 should be 
used.  

NEC Versa LX and SX
-------------------

These machines require BIOS version 42 or better (available for 
download from the NEC web site) when used with Xircom CardBus 
adapters.

Texas Instruments Extensa 650, 660 and 900 
------------------------------------------ 

If using the DOS 16-bit drivers, on the TI Extensa 650 it is 
necessary to insert the CBEM in the top slot. If using the DOS 16-
bit drivers, on the TI Extensa 660 and TI Extensa 900 it is 
necessary to insert the CBEM in the bottom slot.


8) 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 four 
directories, DISK1, DISK2, DISK3, and DISK 4, 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, Windows 98, NT 4.0, and Windows 2000.  DISK3 contains Xircom 
utilities and their install program.  DISK4 contains the Realview 
modem and network utility install.

                 
9) 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:
    Have disk ->
    WIN95CD\\admin\nettools\snmp

    2. Then install the Xircom Extension agent:

    Control panel ->  Network ->  Add ->  Service ->
    Have disk ->

    3. Insert the Xircom CD-ROM

    Then select D:\ 

    Select:
