ally, select Yes. After the hour glass disappears (it may take a
few seconds) verify that the exclamation mark is gone.
Any device attempting to use the same memory segments as
another device will cause the card to fail initialization.
Ideally there should be 12K of contiguous memory starting
with the first 4K block following the video drivers, which
typically load in the C0000-C7FFF range. This varies from
computer to computer. The memory range identified for the
Xircom card is any block in the C0000-E7FFF range. On many
computers, use of the range D0000-DFFFF is optimal. Be
aware that not all blocks of memory are available.
Failure to access to network resources may be due to Win-
dows network configuration issues.

Windows 95 and 98 Driver Parameters
CE3.SYS (NDIS3) Settings
CE3.SYS is an NDIS3 driver. It conforms to the Microsoft Network
Driver Interface Specification (NDIS). CE3.SYS is installed by
default. For NDIS4 instructions, see the README file on the
Xircom Windows 95, 98, and NT Installation Disk.
The files necessary for using CE3.SYS with Windows 95 and 98
include:
NETCE3.INF Xircom install file for Windows 95 and 98
CE3.SYS Xircom NDIS3 driver for Windows 95 and 98
There are user-configurable parameters for the CE3.SYS driver that
can be modified using the Network Control Panel built into
Windows. This applet queries the user for parameter selections
and then sets the corresponding parameters in the registry. The
user-configurable parameters are as follows:

Windows 95 and 98 Installation 2-5

The network node address can be modified by specifying a value
for ‘NetworkAddress’ such as ‘0080C7112233’. If the user does
NOT specify a ‘NetworkAddress’ then the CE3.SYS driver uses the
network node address contained in the RealPort Ethernet 10/100
Card Information Structure.
There are parameters in the Windows registry which specify the
configuration of the RealPort Ethernet 10/100 hardware to the
CE3.SYS driver. Many of these parameters correspond directly to
the user-configurable parameters. These parameters are found in
the registry at the following location:
HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\SERVICES\CLASS\NET\000X

2-6 RealPort Ethernet 10/100 User’s Guide
Under most circumstances it will not be necessary to make
modifications directly to the registry. Incorrect settings can
result in undesirable changes to the configuration of
Windows 95 or 98. Consult Xircom Customer Support for
assistance if you find it necessary to modify the registry.

Troubleshooting
Network Installation
Windows NT 4.0 does not support plug and play resource assign-
ment for the Xircom adapter. Default settings are specified by the
installation files. If these settings do not work on your system, use
the following general guidelines to assist you. Contact Xircom
Customer Support if you are unable to resolve the issues.
Resource Conflict Symptoms
• After network installation the computer locks up on reboot.
• A Service Control message reports that a service or driver
did not start.
• The Xircom card initializes properly, but another hardware
device functions sporadically, the computer locks up
randomly or exhibits very slow network performance.
The most likely cause of these symptoms is a resource conflict
between the Xircom card and another hardware device. Interrupt
conflicts are the most common. Open the Event Viewer to review
errors encountered during the boot process (Start, Programs,
Administrative Tools, Event Viewer). Double-click the bottom
error message to start reviewing. Identification of the device or
service that failed to start may help in pinpointing where the
conflict lies.
Error messages reporting that the driver failed to start
because a device attached to the system is not functioning
may not involve the Xircom card. For example, an error is
sometimes displayed if a device not currently connected to
the computer is still listed as an installed component.
Two items frequently in conflict with the Xircom card are:
Sound cards Often use IRQ 5 and I/O Port addresses 220h
and 330h
PCMCIA.SYS Installs at memory segment D000-D3FF but may
not appear under NT Diagnostics

Windows NT Installation 3-3
Possible Solutions
Remove the card and reboot NT 4.0 normally. Click OK at mes-
sage stating that a Service or Services failed to start. Use the
following steps to evaluate assigned resources and settings:
1Under the Device applet in the Control Panel verify that
PCMCIA status is Started and the Startup setting is Boot. If it is
not change it to start on Boot and then restart the computer.
2Start Windows NT Diagnostics (Start, Programs, Administrative
Tools).
3Under the Version tab note the Service Pack level. The NT 4.0
version is displayed as follows:
MICROSOFT (R) WINDOWS NT (TM) WORKSTATION
VERSION 4.0 (BUILD 1381: SERVICE PACK X)
If no service packs have been applied on Version 4.0, “(Build
1381: service pack X)” is displayed. Or service pack level 1, 2,
3, or 4 will display. Service Packs integrate software upgrades
to your current system and are available from Microsoft.
4Select the Resources tab. By default the IRQ levels in use are
displayed. Verify that the IRQ assigned to the Xircom card is
not in use by any other device. This list is not inclusive and
may not be completely indicative of resources in use.
5Click the I/O Port button. Verify that the I/O Port Address
assigned to the Xircom card is not shared by any other device.
I/O Port 0x280 is usually available. This is displayed as:
0280 - 028E CEM56 BUS 0 TYPE ISA
For an I/O Port Address to be usable the entire I/O range must
be available. For example, the above listed I/O range would be
unusable if another device was using any I/O port within that
range.

Windows NT Driver Parameters
CE3.SYS (NDIS3) Settings for Microsoft Windows NT
CE3.SYS is an NDIS3 NIC driver. It conforms to the Microsoft
Network Driver Interface Specification (NDIS). The CE3.SYS driver
supports the networking environment in Microsoft Windows NT
versions 3.5 and greater.
Windows NT Parameters
Under most circumstances it will not be necessary to make
modifications directly to the registry. Incorrect settings can
result in undesirable changes to the configuration of
Windows NT. Consult Xircom Customer Support for assis-
tance if you find it necessary to modify the registry.
The files necessary for using CE3.SYS include:
CE3.DLL Xircom CE3 installation DLL
OEMSETNT.INF Xircom installation file for Microsoft
Windows NT
CE3.SYS Xircom NDIS3 driver for Microsoft
Windows NT
There are user-configurable parameters to the CE3.SYS driver
which can be modified using the Network Control Panel built into
Windows NT. This applet uses the OEMSETNT.INF file to set the
corresponding parameters in the registry. The user-configurable
parameters are as follows:

Windows NT Installation 3-5
Parameter Default Valid Values Registry
EARLY TRANSMIT ENABLED DISABLED 0
ENABLED 1
FULL DUPLEX DISABLED DISABLED 0
ENABLED 1
INTERRUPT 5 3, 4, 5, 7, SAME

LINK INTEGRITY ENABLED DISABLED 0
ENABLED 1
MEMORY ADDRESS 0XD4000 0XA0000 - 0XFE000 SAME
MODE I/O I/O 0
MEMORY MAPPED 1
The network node address can be modified by manually editing
the registry and adding the parameter ‘NetworkAddress’ with a
hexadecimal string value, such as ‘0080C7112233’. If the user does
NOT specify a ‘NetworkAddress’ then the CE3.SYS driver uses the
network node address contained in the RealPort Ethernet 10/100
Card Information Structure.
There are parameters in the Windows NT registry which specify
the configuration of the RealPort Ethernet 10/100 hardware to the
CE3.SYS driver. Many of these parameters correspond directly to
the user-configurable parameters. These parameters are found in
the registry at the following location:
HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\SERVICES\CE31\PARAMETERS\
