**** GENERAL PRODUCT INFORMATION ****
1. Using DIAGNOSE.EXE
DIAGNOSE.EXE allows you to easily collect information about your computer and
any inserted PC Cards. The information is then used to verify that your
system is running correctly, or to fix identified problems.
To use DIAGNOSE, enter DIAGNOSE and any of the following flags you want to use
with it at the DOS prompt.
The correct format is as follows:
DIAGNOSE /A /D=directory /L /M /? filename
All flags are optional.
The flags are as follows:
/A Print all information without any user
interaction
/D=directory Send or receive files to the specified
directory
/L Test LAN functionality even if not running
under DOS
/M Print in monochrome
/? Print out this list of available flags
filename Save the program results in the specified
file
When you run the DIAGNOSE.EXE program from the DOS prompt, a screen will
appear that gives you a brief description of DIAGNOSE, how to get the results,
and where the results of this session are stored. Press any key to go to the
main menu, where you can select the information.
--------------------------------------------------------
2. Decompressing the Compressed Files on the Megahertz Diskette
You may need a file from the Megahertz Installation and Registration diskette
that was not decompressed during Setup. To decompress the file using
Windows 3.1x, follow these steps:
1. Insert the diskette into the floppy drive
2. At the DOS prompt, enter
EXPAND sourcefile destinationfile
--------------------------------------------------------
3. Disabling IBM Internal Modems
If you are using an IBM Thinkpad 755CSE or other IBM computer that has an
internal modem, you must disable it in order to use your PC Card. To do this,
follow these steps:
1. Load Windows
2. Open the IBM Thinkpad Setup Group
3. Open the DSP Icon
4. Remove the check from the Telephony Function
5. Save
6. Reboot the computer
--------------------------------------------------------
4. Computers With Nonstandard IRQs
Following is a list of machines that contain nonstandard
IRQs, along with the recommended resources.
NOTE: Under DOS, both the LAN and the modem IRQ must be
less than 8 or greater than 8. IRQs of 8 and 11
will not work.

**** CELLULAR PRODUCT INFORMATION ****
6. Cellular Faxing
To avoid receiving unusable cellular faxes, we recommend that you use Class 1
for cellular faxing.
--------------------------------------------------------
7. Connecting to the Internet Over Cellular
It is highly recommended that you connect to your Internet provider using a
landline connection. Most Internet providers are not set up to support and
maintain a cellular connection.
If you need to use a cellular phone system to connect to an Internet provider
with a cellular phone system, contact your local carrier to see if they
provide a cellular modem pool.
- If so, follow your carrier's instructions for connecting with the modem
pool. Contact your Internet provider through the modem pool.
- If not, we recommend that you set your modem startup rate to 4800bps by
setting S79=1.
--------------------------------------------------------
**** ETHERNET/ETHERNET*MODEM PRODUCT INFORMATION ****
8. LAN Driver Placement in AUTOEXEC.BAT
Some computers are configured so Windows is run automatically after each
reboot. When that happens, files that Setup appends to your AUTOEXEC.BAT file
(such as the ODI networking files or the MEGACHEK.EXE program) will not be run
until after you exit Windows.
To correct the problem, use a text editor such as EDIT to go into your
AUTOEXEC.BAT file. Find the WIN or WIN.COM statement and move it to the end
of the file. Save the file and reboot your machine.
--------------------------------------------------------
9. Using NDIS 2 With ENABLE.EXE
The Megahertz PC Card Enabler, ENABLE.EXE, is used to make the resources for
the PC Card (IO, IRQ, MEM) available to the system.
When you use ODI drivers, the driver interacts with the Enabler, which
provides other services for the driver. All Card Service support is in the
Enabler and NOT in the driver.
When you use NDIS drivers, all Card Service support is built into the driver.
If Card Services is available, the driver will enable the Card. If no Card
Services are available, the driver expects the Card to be pre-enabled by means
of a point enabler.
The driver for NDIS2 is called MHZEM.DOS. It must be placed in the CONFIG.SYS
file AFTER the line
DEVICE=ENABLE.EXE /O
--------------------------------------------------------
10. Setting Up Your XJEM3288 or CCEM3288 PC Card Using DOS
This section explains how to set up the LAN portion of your Card without
running Setup and without using Windows. These instructions assume you are
familiar with networks, specifically the network you plan to use.
- Create a directory (such as MHTZ) on your hard disk for the setup files.
- Move to that directory by entering at the DOS prompt
CD MHTZ
- At the DOS prompt, enter
XCOPY /S A:*.*
This will copy the contents of the installation diskette into directory
MHTZ.
- Expand the compressed files (those whose extensions end with _ such as
MHZETH.CO_ (see section 4).
- For an ODI (Novell) network, follow these steps:
o You will need the following files:
ENABLE.EXE
ENABLE.INI
LSL.COM
MHZETH.COM
IPXODI.COM
NETX.EXE
NET.EM
o Rename the NET.EM file to NET.CFG, and edit this file to conform to
your system; for example, if IRQ 5 is not available on your machine,
change the INT parameter to a different number.
o Change the ComboFile parameter in the ENABLE.INI file to read
ComboFile=C:\MHTZ\NET.CFG
o Run the following files from the DOS prompt, or insert them into
AUTOEXEC.BAT:
ENABLE.EXE
LSL.COM
MHZETH.COM
IPXODI.COM
NETX.EXE
(The files must be run or inserted in this order.)
- For an NDIS2 (Microsoft) network, follow these steps:
o You will need the following files:
ENABLE.EXE
ENABLE.INI
MHZEM.DOS
VMHZEMD.386
PROTOCOL.EM
o Rename the PROTOCOL.EM file to PROTOCOL.INI.
o Change the ComboFile parameter in the Enable.INI file to read
ComboFile=C:\MHTZ\PROTOCOL.INI
o Adjust the PROTOCOL.INI parameters (E.g., IOBASE) to conform to your
system.
o Copy this new PROTOCOL.INI and the other files to your NDIS2 directory;
for example, if you are using LANtastic, your directory would be
C:\LANTASTI.
o In the CONFIG.SYS file, the following lines must appear in this order,
but not necessarily consecutively (again, we are assuming LANtastic):
DEVICE=C:\LANTASTI\ENABLE.EXE /O
DEVICE=C:\LANTASTI\PROTMAN.DOS /I:C:\LANTASTI\PROTOCOL.INI
DEVICE=C:\LANTASTI\MHZEM.DOS
PROTMAN.DOS is provided by your network vendor. When you reboot, you
should be able to load your protocol stack. The file VHMZEMD.386 must
be in the same directory as MHZEM.DOS. This file is necessary to use
the modem functions on your Ethernet*Modem under Windows.
------------------------------------------------------
11. Setting Up Your XJ/CCEM3288 Ethernet*Modem Using Microsoft Windows NT
This section details the Ethernet*Modem installation under
Windows NT version 3.51. If you are using a version of Windows NT other than
3.51, contact Microsoft. This section assumes Windows NT is running on your
computer. We recommend that you use COM3 for your Ethernet*Modem. If you use
COM3, skip steps 2 and 3 below.
To install your Ethernet*Modem, follow these steps:
Your Ethernet Combo card is configured to function correctly on COM3 with
Windows NT version 3.51. If your Combo card is configured for any other COM
port, the LAN portion of your Combo card will function, but the MODEM will
not. You can verify your Combo card configuration by looking in the Ethernet
configuration window.
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 and SERIAL.SYS
files with a new version located on the Microsoft BBS.
A PCMCIA.SYS and SERIAL.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.
The PCMCIA.SYS and SERIAL.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/hotfixe s-postSP4/Mhz-fix
Via an ftp utility: /bussys/winnt/winnt-public/fixes/usa/NT351/hotfixes-postSP4/Mhz-fix at ftp.microsoft.com
1. Remove all network adapters and protocols from your computer and reboot.
2. In directory WINNT35\SYSTEM32\DRIVERS\ rename the files PCMCIA.SYS and
SERIAL.SYS as a back up.
3. Download the files PCMCIA.SYS and SERIAL.SYS from the hot fix section of
the Microsoft BBS, and place it in directory WINNT35\SYSTEM32\DRIVERS\.
NOTE: Be sure that the COM port you will be using for the Combo card is
available. If you install to a COM port that is in use, the install will
add a second COM port with the same COM port number.
4. In Windows NT, from the Main group, select Control Panel.

To use the LAN portion of your Card, you must install the network client now.
See your system administrator or network manuals for installation procedures.
------------------------------------------------------
12. TurboTasking Using ODI and NDIS Networks Simultaneously
The Novell ODI driver, MHZETH.COM, has a feature called TurboTasking that can
increase network throughput. Its value is set by modifying the ERX line in
the NET.CFG file. ERX can have a value of 0 to 9. ERX 7 is the default.
ERX 0 turns off this feature.
You must set ERX=0 to connect to both Microsoft and Novell networks
simultaneously.
--------------------------------------------------------
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
