Known Limitations
-----------------
There are presently no known limitations when using a Megahertz PC Card Data/
Fax Modem with Windows 95.
PC Card Ethernet and Ethernet*Modem Limitations
A. Hot swapping (removing the card without Stopping it) while connected
to a network may cause Windows 95 to lock up. To prevent Windows 95
from locking, stop the PC Card before removing it. This will log
you out of the network. You must reinsert the PC Card and log into
the network to begin accessing network resources again.
To stop the card, double click on the PC Card icon on your task bar.
The PC Card (PCMCIA) Properties dialog will be displayed. Click on
the PC Card you wish to remove and click on the Stop button. Windows
will then notify you that it is safe to remove the PC Card from your
computer.
B. These drivers have not yet been certified by Microsoft.

D. Some earlier versions of the LAN-T and LAN-2 PC Card Ethernet
Adapter may not be automatically recognized by Windows 95. They
must be manually installed by using the Add New Hardware applet in
the Windows 95 Control Panel. To manually install a LAN-T or LAN-2
PC Card Ethernet Adapter, perform the following steps:
a. Open the Windows 95 Control Panel and select the Add New
Hardware applet. Click Next.
b. When prompted to have Windows 95 search for new hardware,
select No and then click Next.
