1. Description of this release
-----------------------------
This document details installing the Ethernet*Modem under Windows NT version 3.51. This document assumes Windows NT 3.51 is installed and running on your computer.  If you have not installed Windows NT 3.51 yet, install it and select No Network during installation.


2. Before you begin
---------------------
This Windows NT driver requires that you upgrade the firmware to revision AC02F. Read PFWIN.TXT and AC02F.TXT in the \AC02F directory of this diskette for installation instructions and information on the firmware upgrade.
 
We recommend that you use COM3 for your Ethernet*Modem.  The Ethernet*Modem driver will function correctly on COM3.  If your Combo card is configured for any other COM port, the LAN portion of your Combo card will function, but the MODEM portion will not. If you plan on using
COM3, skip to section 4 below.


3. PCMCIA.SYS Information
---------------------------
Microsoft has confirmed this to be a problem with Windows NT version
3.51.  To correct this problem, you will need to replace your
PCMCIA.SYS file with a new version located on the Microsoft FTP site.

A PCMCIA.SYS correction is now available (HOTFIX #Q152124) but is not
fully regression tested and should be applied only to systems
experiencing this specific problem. Unless you are severely impacted
by this specific problem, Microsoft recommends that you wait for the
service pack release containing this fix.  Contact Microsoft Product
Support Services for more information.


4. Obtaining and replacing PCMCIA.SYS
-----------------------------------------
The PCMCIA.SYS correction and installation instructions can be
obtained from Microsoft at the following location.

Via a web browser:
  ftp://ftp.microsoft.com/bussys/winnt/winnt-public/fixes/usa/NT351/
hotfixes-postSP4/Mhz-fix

Via an ftp utility:
  Location:  ftp.microsoft.com
  Directory: /bussys/winnt/winnt-public/fixes/usa/NT351/hotfixes-postSP4/
Mhz-fix

Rename PCMCIA.SYS in the \WINNT35\SYSTEM32\DRIVERS directory.

  Download PCMCIA.SYS from the hot fix section of the Microsoft FTP
site, and place it in the WINNT35\SYSTEM32\DRIVERS directory.


5. Installing the driver
----------------------------
 After logging onto Windows NT, select Control Panel from the Main
group and double-click on Network.

..  If you already have protocols listed in Installed Software, go to the Add Adapter section. 

Otherwise you will be asked if you want to install the network now?  Click on Yes.

Type the path for the Windows NT 3.51 diskettes or CD and click
on Enter.

 The Network Adapter Dialog box will appear.   Click on Do Not
Detect, then click on Continue.

 From the Add Adapter Dialog box, select  <Other> Requires disk
from manufacturer and click on Continue.

 Insert the Megahertz Installation and Registration diskette into
the floppy drive.

 Change the path to A:\WINNT and click on Continue.

 The Select OEM Option dialog box will appear.  Highlight Megahertz
XJEM3288 Ethernet*Modem PCMCIA Adapter and click OK.

 The Megahertz PCMCIA Card Setup will appear.  Ensure that the values listed are correct for your machine (consult your computer manuals or network administrator for more information.

If you want to change values, use the drop-down menus to select new 
values.  Click on Continue.

NOTE:  The network and modem will share the same IRQ.


6. Configure Network and Protocols
---------------------------------------
 The Windows NT Setup screen will appear.  Select the services and
protocol(s) you require for your network (see your network administrator and
Windows NT manuals for the correct information) and click on Continue.

 Insert the Microsoft Windows NT diskettes or CD into the drive as needed.

 The Network Settings screen will appear.  Note that the Installed
Adapter Card is the Megahertz XJEM3288 PCMCIA Adapter.  Click on OK.

NOTE:  The NETWORKS and WORKGROUPS buttons are grayed out during the
initial installation.  After the first reboot, you will be able to
access them.

NOTE:  You cannot configure the card settings in the NETWORK SETTINGS
menu until after you reboot the first time.

 A Network Setup Warning will appear, stating that the network was
unable to start.  Click on OK.  You will then be asked if you want to
reconfigure the card.  Click on NO.


7. Choose your Domain/Workgroup
----------------------------------
 The Domain/Workgroup Settings screen will appear.  Type in these
values (see your network administrator for more information) and click
on OK.

 When the Restart screen appears, click on Restart Computer.


8. Add Adapter
----------------
Put the diskette in with the extracted Megahertz Windows NT drivers. 
Select Add Adapter.
Select <Other> Requires disk from manufacturer and click on Continue.
Change the path to A:\WINNT and click on Continue.
Choose the XJEM3288 Megahertz Ethernet*Modem Adapter and click on OK.
The installation will then copy files.
Change the I/O Port, IRQ Level, and Memory Window, Media Type, and COM Port settings for what you will be using and click on Continue.
Click OK in the Network Settings Dialog box.
Click on Restart Computer.


Congratulations!  Your Ethernet*Modem is enabled.

Note:  If you have installed a Microsoft Service Pack, you will need
to re-install the service pack after the network is completely
installed. Then you will need to recopy PCMCIA.SYS to the
C:\WINNT35\SYSTEM32\DRIVERS directory.


9. Troubleshooting
----------------------
You can verify which COM port your Combo card is configured for by
checking Main->Control Panel->Network.  Highlight the Installed
Adapter and select Configure.  Note the COM port setting.

If you do not have the updated pcmcia.sys installed, you will get 6-7 entries for Pcmcia Error 0006 in Administrative Tools->Event Viewer.  The modem and network should still work.

Even if you don't see a server, check Administrative Tools->NT Diagnostics->Network->Statistics.  You should see bytes received/transmitted.

All the installable ranges may not be supported by the card. Do not install to these IO Ports: (180, 1A0, 1C0, 1E0, 280, 2A0, 2C0, 3E0).
