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.

    C.  These drivers will not support promiscuous mode.

    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.

           c.  From the list of hardware items, select Network Adapters and
               click Next.

           d.  In the Select Device dialog box, click Have Disk.  Make sure the
               Megahertz MHZWIN95 driver diskette in inserted in the computer.
               Select A:\ as the source and click OK.

           e.  Select LAN-T from the list of Megahertz Network Adapters - even
               if you have a LAN-2 - and click OK.  Windows 95 will install the
               necessary software.  If you have a LAN-2, you will need to
               change the media type to 10-Base-2 as outlined in the section
               below.
