Description

The program SETUP is used to install your LAN + Modem PC Card under Windows 3.1 and Windows 95.  After installing your combo card, you need not run SETUP again.


Inserting Your PC Card

Laptop computers typically have one or two slots located on either side of the machine into which PC Cards are inserted.  The LAN + Modem PC Card should be removed from its plastic case before being inserted into the computer.  The top of the card has an arrow indicating which end should be inserted into the computer.

NOTE:

On some new laptop computers, a plastic card is shipped in the PC Card slots to protect them during shipment.  Before inserting your LAN + Modem PC Card, inspect your PC Card slots and make sure they are free of any obstructing materials.

Some laptop computers require that the combo card be inserted upside down.  If you have difficulty getting the card all the way in, try turning the card over and inserting it again.


Create Directory

The path C:\MHZ is only a suggested default directory where the LAN + Modem PC Card drivers and other support files will be copied.  It is best that the directory you use does not already exist on your system.  You can change the directory by entering any unique directory path.  If the directory specified does not exist, it will automatically be created when the files are copied to it.


Select Network

See your Network Administrator to determine the network you are using and the type of wire connection.  If using a Novell (ODI) Network, you will also need to know the Preferred Server and the Frame Type currently being used.

Available Network Operating Systems:

Novell Netware (ODI)

NDIS2 Network

The NDIS2 Network driver is used by Windows for Workgroups, Banyan Vines, Artisoft LANtastic, and several other network operating systems.  When installing the NDIS2 driver, refer to the network operating system documentation for installation instructions.


Twisted Pair Cable

Wiring consisting of two insulated wires loosely twisted around each other.  This helps reduce noise on circuits.


Thinnet Cable

A cabling scheme using RG-58 50-ohm coaxial cable.  Also called Thin Ethernet.


Network and Frame Type
ODI Network and Frame Type

Preferred Server:

Some networks have more than one file server attached.  The Preferred Server is the server chosen if more than one is available.  See your Network Administrator to determine the Preferred Server Name needed as your default.

Frame Type:

Networks send information from one computer to another in a block of data called a packet.  A packet is a group of bits (data and control characters) that are transmitted as a whole.  The packet standards are:

Ethernet 802.2

Ethernet 802.3

Ethernet II

Ethernet SNAP

See your Network Administrator to determine the frame types to use.


DOS Installation

A DOS installation program is not available at this time.  However, if you install your LAN + Modem PC Card using the Windows 3.1 installation program, then your combo card will also work under DOS.


Windows 3.1 Installation
Windows 3.1 or Windows for Workgroups Installation

To enable your LAN + Modem PC Card under Windows 3.1 or Windows for Workgroups, you need to have Card Services or a Point Enabler installed.  These programs are required to enable the combo card.  When you run SETUP, it will automatically detect whether or not you have Card Services running, and use them if they will work.  If no Card Services are installed, SETUP will give you the option of installing a point enabler.  Because of the limitations with a point enabler, SETUP will always recommend that you install Card Services instead of installing a point enabler.  See the Point Enabler section of this help file for more information.

NOTE:

 System files are backed up to Filename.M00.

Sample:  CONFIG.SYS => CONFIG.M00

Restore backup files only immediately following the LAN + Modem PC Card installation. Restoring these files may delete changes made to system files or programs loaded after SETUP was run.


Card Services

NOTE:

"Card Services" and "Card and Socket Services" refers to the same set of programs.  In this section, we refer to this software as "Card Services" for consistency.

This information refers to Card and Socket Services running under DOS.  If your computer is running Windows 95, check the section on Windows 95 Card Services instead.

Card Services is a system of software files that are shipped with almost every laptop computer that runs DOS.  If SETUP detects a recent version of Card Services on your computer, it will automatically use them.  If no Card Services are installed, SETUP will give you the option of installing a point enabler.  Because of the limitations with a point enabler, SETUP will always recommend that you install Card Services instead of installing a point enabler.  See the Point Enabler section of this help file for more information.

Card Services will automatically detect when a PC Card is inserted or removed, and enable it correctly.  This allows you to "hot-insert" your LAN + Modem PC Card whenever you need it.  With Windows 3.1 or Windows for Workgroups, hot-insertion may not work correctly -- depending on the version of Card Services you are using.  If you cannot use your combo card after hot-inserting it under Windows, try exiting to DOS (not just a DOS box), reinserting your combo card, and restarting Windows.

If you are having problems with your Card Services, we recommend you contact your laptop vendor for an updated version.


Point Enabler

A point enabler is software that activates specific resources on your computer so you can use your LAN + Modem PC Card.  The combo card must be inserted when the point enabler is run, and the point enabler must be rerun every time the card is reinserted, the computer is restarted, and possibly even when the computer goes to sleep.  To be able to use the point enabler, you must specify what resources the LAN + Modem PC Card will use.  Card Services, on the other hand, keeps track of available resources for you.

Because of the limitations of using a point enabler, it is highly recommended that you use Card Services when using your LAN + Modem PC Card.  The advantage of using a point enabler is that it uses less conventional memory.  If you need the memory used by Card Services, you can disable them and run SETUP to have the point enabler installed.

When a PC Card is reset, information about the card is written to computer memory.  This information is referred to as tuples.  These tuples are needed by Card Services or most point enablers to tell the program exactly how to configure the card.

When using the Megahertz point enabler, a 4 kilobyte block of memory needs to be available in upper memory for the PC Card to use when writing out its tuples.  If an extended memory manager, such as EMM386, is loaded before the point enabler is run, then a block of memory needs to be excluded from the memory manager's control.  For example, if you were using the EMM386 extended memory manager, and you wanted to use the block of memory starting at D000:0, then you would add the instruction X=D000-D0FF to the EMM386 command line.  You must specify a block of memory that is not being used.


Windows 95 Installation

Windows 95 includes its own PC Card installation program.  SETUP will monitor the Windows 95 LAN + Modem PC Card installation, giving you hints about how to proceed, and correcting any problems it finds.

SETUP also makes sure that the necessary software to use LAN + Modem PC Cards is installed.  (See Windows 95 Card Services for more information on this.)


Windows 95 Card Services

NOTE:

"Card Services" and "Card and Socket Services" refers to the same set of programs.  In this section, we refer to this software as "Card Services" for consistency.

If you are not using Windows 95, please refer to DOS Card Services instead.

Windows 95 has built-in support for PC Cards included.  These built-in Card Services allow "hot-swapping" and automatically detect when a PC Card is inserted or removed.  It also recognizes many kinds of PC Cards, including 3Com LAN + Modem PC Cards.

When SETUP is run, it will detect which Card Services are installed.  If you have DOS Card Services installed, or the Windows 95 built-in Card Services are not enabled, SETUP will give you the option of installing Windows 95 Card Services.  Unless there is a special reason to keep DOS Card Services (such as compatibility with a specific PC Card), it is highly recommended that you install Windows 95 Card Services.

Reinstalling the LAN + Modem PC Card

If Windows 95 does not recognize your LAN + Modem PC Card after the installation is completed, the card needs to be reinstalled.  The following steps explain how to do this:

     1.	Press the Start button

     2.	Select Run

     3.	Type   C:\MHZ\UNINSTAL   and press ENTER

     4.	Follow the instructions

     5.	Use the Installation Guide and Installation diskettes to completely reinstall your combo card

Windows 95 and CardWizard

There are some conflicts with SystemSoft's CardWizard for Windows 95 and 3Com LAN + Modem PC Cards.  If you have installed a 3Com or Megahertz combo card while not running SETUP on a machine with CardWizard installed, you may not have the full functionality of your combo card, or it may work incorrectly.  To correct this problem, follow the steps above to reinstall your combo card.

If this does not correct the problem, please contact your laptop vendor for assistance.


Windows NT 3.51 Installation

This section describes how to configure the LAN + Modem PC Card for use with Windows NT 3.51 (in server or workstation mode) and Microsoft Windows networks.

To install your PC Card under Windows NT 4.0, go to the Windows NT 4.0 Installation section.  If you have Windows NT 3.50 or earlier, you must upgrade your system to 3.51 or later.  Windows NT versions prior to 3.51 do not have PC Card support and do not support the LAN + Modem card.
