3) RELEASE NOTES/KNOWN LIMITATIONS 
   ===============================

Creating Diskettes
------------------

Installation diskettes (1.44MB) may be created if needed by running 
MAKEDISK.BAT and following the on-screen instructions.



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

This driver release now supports automatic NDIS version selection
for installs under Windows 9X and Windows 2000. For installs under 
Windows 9X or Windows 2000, direct the install to the root of the 
CD or of Disk 2 when the drivers are requested.

The network property page tab of the CE3 has a new entry 
"NdisVersion". This entry contains the following:

Under

Windows 95: 	   AutoSelect, NDIS3 
Windows 95OSR2:    AutoSelect, NDIS3, NDIS4
Windows 98: 	   AutoSelect, NDIS3, NDIS4, NDIS5
Windows 98SE: 	   AutoSelect, NDIS3, NDIS4, NDIS5

Windows Millenium: "NdisVersion" does not exist and NDIS5 is the
Windows 2000:      default driver. The Ndis Switcher is not used 
                   with Windows Millenium or 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.

NDIS switching is not supported in Windows NT 4.0.  The NDIS4 driver 
will be installed by default by pointing to the root of the CD or of 
Disk 2 if diskettes are created.  The NDIS3 driver may be installed 
by pointing to the \NDIS3 subdirectory.


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 while the network card is inserted, these 
packets may not be routed to the dial-up interface because the 
presence of the active LAN interface results in the system 
continuing to route packets to it instead.  In such instances, 
the simplest solution is to remove the LAN interface from the 
computer, or to use a network disabled profile. If neither of 
these solutions is satisfactory, a third option is now available.

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, 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.

USING THE CE3/CE3B/RE-100/R2E-100 ADAPTERS IN WINDOWS NT WITH SOFTEX 
--------------------------------------------------------------------
CARD SERVICES
-------------

To install the adapter with Phoenix CardExecutive or Softex, 
perform the following steps:

Caution: Do not insert the Xircom CD-ROM until instructed to 
do so in step 3.

1. With Windows NT 4.0 running, connect cables and insert the 
RealPort Ethernet 10/100 into the PC Card slot. The 
"PCMCIA Card Not Configured" screen will appear.

2. On the "PCMCIA Card Not Configured" screen, select "Install 
the driver that was provided with the PC Card" and click OK. 
The "Path Not Found" screen will appear.

3. When the "Path Not Found" screen appears, insert the Xircom CD-
ROM and type the path to the \CE3NT directory (for example, 
D:\CE3NT). Click OK.

4. The Xircom Ethernet 10/100 for Softex - Properties     
window will display default network and modem settings. Click 
Continue. 

5. The "PCMCIA Configuration Complete" screen will appear. Click 
OK. Restart the computer by clicking Yes if prompted, or by clicking 
Start, Shut Down, Restart. 


USING THE CE3/CE3B/RE-100/R2E-100 ADAPTERS IN WINDOWS 2000 
----------------------------------------------------------

 Note: Windows 2000 does not have built-in drivers for the R2E-100, 
 and the update procedure given in steps 1, 2, and 3 below does not 
 need to be followed for the R2E.  The R2E may be installed directly 
 from this driver set by pointing to the root of either the CD-ROM 
 or Disk 2 when Windows requests the drivers.  The correct driver 
 will automatically be installed. Then continue with step 4 below.

Windows 2000 contains built-in drivers for the Xircom RE-100, 
CE3, and CE3B, as well as many other Xircom Cards.  The built-in 
drivers are functional but lack some features of this release.  To 
update the Windows 2000 driver, do the following:

1.  You will need to have the Xircom RE/CE3/CE3B 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 CreditCard Ethernet Adapter 10/100.  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 10/100 with a path listed to your driver CD 
or diskette).  Pick the Xircom driver, and click Next.

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


Supported Environments
----------------------  

With this release, the following environments are supported: 

-NDIS3 Driver for Microsoft Windows NT (Ver. 3.50, 3.51, 4.0), 
 Windows 95, and Windows 98 (CE3.SYS)
-NDIS4 Driver for Microsoft Windows 95 OSR2, Windows 98 and 
 Windows NT 4.0 (CE3N4.SYS)
-NDIS5 Driver for Windows 98 and Windows 2000 (CE3N5.SYS)
-DOS ODI Driver (CE3ODI.COM)
-DOS NDIS2 Driver (CE3NDIS.EXE)
-Packet Driver (CE3PD.COM) 
-NDIS2 Driver for OS/2 (CE3NDIS.OS2)
-ODI Driver for OS/2 (CE3ODI.OS2)
-NetWare Server Driver (CE3ODI.LAN) 
-DOS Diagnostic test program (CE3TEST.EXE)

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

-To utilize the new NDIS switcher feature in Windows 98 after a 
driver update, it is necessary to open the Network Option in Control 
Panel, and click OK.  The appropriate NDIS driver will be used upon 
reboot. 

-Full-duplex operation is only supported at 10Mbps. Full-duplex 
is not supported at 100Mbps. The LineMode keyword has no effect on 
performance at 100Mbps. If the LineSpeed keyword is set to 100Mpbs 
and the LineMode keyword is set to full-duplex, the LineMode keyword
will be ignored. Full-duplex at 10Mbps is only available when the 
adapter is connected to a full-duplex capable switch or hub.

-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 CE3 and in some cases the CE3B are not capable of negotiating 
to 10 Mbps Full-Duplex mode. On these adapters, in order to operate 
in full-duplex mode, the LineSpeed keyword must be set to 10Mbps 
and the LineMode keyword must be set to Full Duplex. The Cable Type 
keyword can be set to Auto Detect or 10BT/100BTX. The corresponding 
port on the attached hub or switch should also be set to 10Mbps 
full-duplex.

-The CableType keyword (CE3-10 only) has precedence over the 
LineSpeed and LineMode keywords. If CableType is set to 10B2 (Coax), 
the LineSpeed and LineMode settings will be ignored. The adapter 
will be configured for 10Mbps, half-duplex.

-If the CableType keyword is set to Auto Detect and a LAN cable is 
not attached to the adapter when the machine boots, the adapter will 
be configured for Coax, 10Mbps, half-duplex (this situation is 
applicable to a CE3 with the 10BT LAN cable only). If you need to 
hot attach a twisted pair cable after the adapter is started, set 
the CableType keyword to twisted pair (TP). 

-If a 10BT or 10B2 LAN Cable is attached to a CE3 adapter, the 
LineSpeed setting will be ignored (i.e., the adapter will operate 
at 10Mbps even if LineSpeed is set to 100Mbps).

-A 10BT LAN Cable, when attached to a 100Mbps only hub, will report 
link (at the LED) but will fail to operate correctly (i.e., will be 
unable to transmit and receive data).

-It is normal to see the link LED at both the LAN Cable and the hub 
come on, then off, and then on again as the adapter attempts to 
establish link. This situation will only occur with the CE3 (with 
the 10/100 LAN Cable) and early versions of the CE3B.  Additionally, 
this only occurs if the network cable is attached after the host 
machine is powered-on or the network cable is removed and then 
reinserted after power-up.

-If the network cable is attached after host power-up, the user 
may see the collision LED on a 10Mbps hub go on for a short period 
of time. This situation is applicable only to the CE3 (with the 
10/100 LAN Cable) and early versions of the CE3B.

-If "Link Integrity" is disabled, the LineSpeed and LineMode 
settings will be ignored (i.e., the adapter will operate at 10Mbps, 
half-duplex).

5)  TYPOGRAPHICAL AND CONTENT CORRECTIONS 
    ===================================== 

    a) Under the Installation Troubleshooting section in the online 
    documentation, any reference to "CardBus adapter" should be to 
    "adapter". Any reference to "CardBus adapters" should be to 
    "adapters" any reference to "CardBus PC Card slot" should be to 
    "PC Card Slot", and any reference to "CardBus drivers" should be 
    to "drivers".

       For example, "1. With Windows running, insert the Xircom 
       Ethernet PC Card into the CardBus PC Card slot...." should 
       be "1. With Windows running, insert the Xircom Ethernet PC 
       Card into the PC Card slot...."

    b) All references to RE-10 in the online documentation do not 
    apply in this release.
