About Windows 95
Prompts

During setup, Windows 95 may prompt for an Installation Disk or the Windows
CD several times. Be sure that the path or device you supply to this prompt is
correct. Here are some guidelines:

■

If Windows 95 prompts for a disk from the manufacturer, put the LAN+Modem
card

Windows 95/98 Installation Disk in the floppy drive. On most systems, this

will be drive A, so the path in the dialog box should point to A:\.
If Windows 95 prompts for the Windows CD, put the Windows 95 CD in your

■

CD-ROM drive. Often, this will be drive D. If so, the path in the dialog box
should point to D:\WIN95.

■

Some computers are delivered with Windows 95 installed, but no CD is
supplied. If this is the case with your computer, you must supply the path
where the Windows 95 software resides. Check your owner’s manual for
details. Often, this will be a subdirectory of your Windows folder. A common
path for these driver files is C:\WINDOWS\OPTIONS\CABS, so you would supply
this path in the dialog box.

Uninstalling the Card If the card installation is unsuccessful for any reason, your best course may be to

remove the card and its software and repeat the installation procedures with a
fresh installation of the operating system.

Sometimes earlier installations or interrupted installation attempts leave problems
that affect card operation. Possible problems include:

■ One or both of the card functions not working.

■ Windows 95 not detecting the card.

■ The system issuing a warning tone at startup.

If you are having any of these problems, remove the LAN+Modem card and
software using the procedures below, then reinstall the card.

Removing the Card Check your computer manual for information on removing cards. Store the car d in

its original or similar packaging.

CAUTION: Exit any communications or networking applications before
removing the card.

Removing Card

Troubleshooting

Symptom Solution

Basic Troubleshooting, applicable for all
problem situations.

System shows a valid COM-Port setting for
the modem, but your application does not
recognize it.

The LAN device is not functional. LED on the
connector is off or mismatches the real
network speed.

After you remove the card from the system
and then inserted back – Windows runs
installation process again.

Inspect all cables and connections.
Check whether your card if fully inserted into the slot.
Verify whether you have the latest BIOS for your system. If not, check the Web

site for your computer, download the newest BIOS version, and follow the
upgrade instructions.

Check for multiple installations of the card.
Check whether your system’s PC Card CardBus Controller is installed and

running properly: go to Control Panel/System/Device Manager/PCMCIA Card
and verify that the controller is present and shows no errors.

Check the Control Panel/PC Card application to confirm that your card is
recognized by the system.

In the Control Panel/Network application, make sure that you have appropriate
clients and protocols installed.

Use the 3Com Modem Setting application in the control panel to change the
COM port assignment. The default is COM5. Use a lower number if you are
have older software that does not recognize COM ports higher than 4.

Use Control Panel – Device Manager to inspect the status of your LAN card.
If you see a red X, enable the card and set the Properties.
If yo see a yellow exclamation mark, click on the icon to see what the conflict is.

Verify that there are adequate system resources. Try to free system resources
(e.g. disable the infrared port), then remove and reinstall the card.

This is normal behavior for Windows with PCI and CardBus cards installed.
Windows 95 can install one instance of the card for every slot presented in the
system. You will have two instances of the card under the Network and Modem
applications in Control Panel. After the second instance is installed – the hot
swap from one slot to another will be smooth. Be sure to check your settings
under Dial-up Networking and Hyperterminal to ensure that your preferred
settings apply to the correct instance of the card.

The card does not work in your system with
Windows 95 or Windows 95a

Losing network connection after
disconnecting or changing the media speed
when using NetWare servers and IPX/SPX
protocol

After reboot in Dell Latitude CP the card does
not come up.

Earlier versions of Windows (Windows 95 and Windows 95a) are not
supported. Upgrade your system to Windows 95b (OSR2) or Windows 98.

To determine your version of Windows 95, open the Control Panel, select
System, and look at System information under the General tab. If your release is
identified as version 4.00.950 B, you are using OSR2.

This happens when the frame type is selected automatically. A temporary
solution is to reboot after disconnecting and reconnecting the cable in NetWare
networks. The permanent solution is to use specific frame types such as 802.2
or 802.3.

A temporary solution is to remove the card from the slot and then insert it
again. For a permanent solution, use the original Dell Windows 95 installation
CD or obtain QFE 515, 567 and 599 from Microsoft or Dell. Copy these files
into the Windows/System folder.
