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. ------------------------------------------------------------------------- Computer Recommended Recommended Recommended Mem Exclude COMPort/IRQ LANBase IRQ ------------------------------------------------------------------------- Ambra Notebook D000-D3FF 3 12 Not Ethernet Compatible Ambra Subnote C800-CFFF 3 9 300 5 AMS Soundpro C800-CFFF 3 9 300 10 Austin Business Audio D000-D7FF 3 5 320 7 DEC Ultra Highnote D000-DFFF 4 3 320 10 Epson ActionNote 4000 D000-DFFF 3 5 300 10 Eurocom 9200 D800-DFFF 4 5 300 15 Durocom 9600 D800-DFFF 4 5 300 15 Gateway Handbook D000-DBFF 3 5 300 5 Gateway Colorbook D000-DFFF 3 5 300 5 HP Omnibook 4000 D000-DFFF 3 5 320 10 Hyundai Neuron D000-DFFF 3 5 Not Ethernet Compatible Panasonic CF-41 CC00-CFFF 3 5 300 10 Sharp 8650 C800-CFFF 3 5 Not Ethernet Compatible Sharp 8900 D000-D7FF 3 5 300 5 TI Travelmate 4000 C800-CFFF 4 3 320 7 TI Travelmate 5000 C800-CFFF 4 3 320 7 The HP Omnibook 600C has a proprietary PCMCIA controller that is not supported by the Ethernet*Modem. -------------------------------------------------------- 5. Switches Available With ENABLE.EXE The following command line switches can be used with ENABLE.EXE: Modem: /Cn COM port 1, 2, 3, 4 LAN: /Bnnn LAN I/O base address in hex /Nn..n LAN node address in hex /O Use the point enabler only Combination: /ILn LAN IRQ /IMn Modem IRQ /L Enable LAN functions only /M Enable modem functions only General PC Card: /Dnnnn Delay in milliseconds (specifically for IBM 755 and 360 models) /In IRQ 3, 4, ... 15 /Pnnnn Attribute memory window segment address in hex /Sn PC Card slot A to H /U Disable the Card /V Display verbose status messages /H or /? Display switches available with ENABLE.EXE -------------------------------------------------------- **** 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. 5. Double-click on Network. 6. You will be asked if you want to install the network now? Click on Yes. 7. Type the path for the Windows NT 3.51 diskette or CD and click on Enter. 8.

NOTE: The network and modem share the same IRQ. 14. The Windows NT Setup screen will appear. Select the services and protocol(s) your network requires (see your network administrator and Windows NT manuals for the correct information) and click on Continue. If you did not select TCP/IP, skip to step 16. 15. If you selected TCP/IP protocol, the Windows NT TCP/IP Installation Options screen will appear. Type or select the options you want to use and click on Continue. If you need more information, see your network administrator. 16. Insert the Microsoft Windows NT diskette or CD into the drive. 17. 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, they will return to normal. NOTE: You can not configure the card settings in the NETWORKSSETINGS menu until after you reboot the first time. 18. If you are using NWLINK IPX/SPX compatible transport, select Auto Detect and click OK. If you did not select TCP/IP in step 14, skip to step 20. 19. If you selected TCP/IP in step 14, the TCP/IP Configuration screen will appear. Type the correct address (see your network administrator if you need more information), and click on OK. 20. A Network Setup Warning will appear, stating that the network was unable to start. Click on NO. You will then be asked if you want to reconfigure the card because of the error. Click on NO. 21. The Domain/Workgroup Settings screen will appear. Type in these values (see your network administrator for more information) and click on OK. 22. When the Restart screen appears, select Restart Computer. Congratulations! Your Ethernet*Modem is enabled. Under certain configurations in Windows NT you may not be able to hear audio. 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. -------------------------------------------------------- 13. Decompressing the Communication Package Script files This disk contains scripts for several of the popular communication packages. To decompress these files from the installation diskette to your hard drive, type the following command: a:\script.bat This will decompress the files onto your C drive in a Scripts subdirectory.
