This document includes general tips for troubleshooting Xircom® PCMCIA adapter under Windows* 95 Retail Version. The first step is to determine which version of Windows 95 is installed on your computer. To do this, double-click the System icon in the Control Panel. The System Properties window, General tab is displayed by default. The tab displays the following:

• Microsoft Windows 95 4.00.950 » indicates the original retail version
  
  
• Microsoft Windows 95 4.00.950A » same as above but with Service Pack 1

1. Select Start» Shut Down » Shut down the computer? (default) and click OK.
   
   
2. Leave the computer off for a few seconds before applying power to the computer.
   
   Note: DO NOT use CTRL+ALT+DEL or the computer's RESET button to restart your computer. On some machines, all hardware is not reset unless power is cycled.

• Use the latest firmware and driver for your adapter.
• Run the Xircom self-test utility (XPSTEST.EXE), if available, in DOS.
• Verify PCMCIA support in Windows 95.
• Change the resources of the adapter to resolve conflicts.
• Reinstall the Xircom adapter to resolve configuration errors.<
• Create a MODEMLOG.TXT to help resolve issues with the modem.
• Check for hardware/software specific issues.

1. Restart Windows 95 in MS-DOS mode (Start » Shut Down » Restart Computer in MS-DOS mode, OK).
   
   
2. XPSTEST.EXE for example, is the self-test utility that can be found on the Network Drivers disk for the CE2, CEM28, or CEM33 adapters. Refer to the Xircom User's Guide for instructions on running the Xircom self-test utility.
   
   
3. If the self-test does not work in DOS, attempt the procedure on another computer, if possible. The self-test utility will not run on computers that require DOS card and socket services to initialize the PCMCIA slot. If the adapter still does not work, go to the next section or contact Xircom Customer Support for further assistance.

1. Right-click My Computer, select Properties and click the Device Manager tab.
   
   
2. In Device Manager, expand either the Network adapter entry or Multifunction adapter entry depending on your adapter (single function and combo adapter, respectively).

3. Open the MS-DOS prompt and delete the following files:
   
   
   C:\WINDOWS\INF\DRVDATA.BIN
   C:\WINDOWS\INF\DRVIDX.BIN
   C:\WINDOWS\INF\SX*.INF
   
   
4. If this is a Windows 95 upgrade from Windows 3.x, rename the CONFIG.SYS and AUTOEXEC.BAT files. Use these commands:
   
   
   REN C:\AUTOEXEC.BAT C:\AUTOEXEC.X0X
   REN C:\CONFIG.SYS C:\CONFIG.X0X
   
   If the computer was pre-loaded with Windows 95 at the factory, edit the CONFIG.SYS and change the EMM386.EXE line to read:
   
   
   DEVICE=C:\WINDOWS\EMM386.EXE NOEMS
   
   
5. Edit the SYSTEM.INI (located in the Windows directory). In the section labeled [386Enh] disable all EMMEXclude statements by placing a semi-colon at the beginning of the line - for example:
   
   
   [386Enh]
   ;EMMExclude=D000-DFFF
   
   Now add a line to the [386Enh] section as follows:
   
   
   [386Enh]
   EMMExclude=C000-CFFF
   
   
6. Shut down Windows 95 and power off the machine.
   
   
7. Remove the Xircom adapter physically from the PC Card socket.
   
   
8. Allow Windows 95 to boot fully. In Control Panel, double-click the PC Card (PCMCIA) icon. Ideally the PC Card Properties window will display Empty Socket. However, if the PC Card wizard appears, accept the default No answer to each question. Click Finish, and then Yes to restart Windows 95. Windows 95 will shutdown not restart as stated. This is standard procedures, when completely of restart the computer and allow it to boot fully.
   
   
9. After Windows 95 fully boots and all drive activity has stopped, reinsert the adapter. Windows 95 will automatically detect the Xircom adapter during startup and prompt for a Disk provided by the manufacturer or the location of the driver files depending on the version installed. Insert the appropriate Xircom disk or provide the path to the these drivers, and follow the prompts to complete the installation.
   
   
10. Windows 95 will add the Xircom adapter in Device Manager under and prompt for the Windows 95 source files to install the various Network components. The source files are located on the Windows 95 disks or product CD-ROM for upgrades and on system pre-loaded with Windows 95 these files are located in the WINDOWS\OPTIONS\CABS directory. Windows 95 includes 32-bit Clients for:
    
    
    • Microsoft Networks
      
    • Novell NetWare* Networks
      
    
    32-bit Network Clients are available from the respective manufacturers for the following:
    
    
    • Novell NetWare
      
    • Artisoft LANtastic*
      
    • DEC Pathworks*
      
    • Banyan VINES*
    
    
11. Restart the computer for the installation to take effect.

1. Verify that you are using the latest firmware and driver for your adapter.
   
   
   1. In Control Panel, double-click the Modem icon.
      
   2. Select the Xircom modem, click the Diagnostics tab.
      
   3. Choose the port assigned to the Xircom modem and click More Info... . The ATI3 line displays the adapter firmware information for your adapter.
   
   
2. Verify the following entries in the SYSTEM.INI (located in the Windows directory):
   
   
   [BOOT]
   COMM.DRV=COMM.DRV
   
   [386enh]
   DEVICE=*VCD
   ;DEVICE=C:\TRANXIT\PCOMM2.386
   ;DEVICE=C:\TRANXIT\PUMAIR.386
   ;DEVICE=C:\TRANXIT\PUMAFIR.386
   
   Note: Entries in the [386Enh] section may or may not be present. If present, ensure they reflect the same as above.
   
   
3. Create a MODEMLOG.TXT file to review the status of the modem. Follow these steps to enable this feature:
   
   
   1. In Control Panel, double-click the Modem icon .
      
      
   2. With the Xircom modem selected, click Properties, select the Connection tab, and click the Advanced button.
      
      
   3. Now place a check mark in the box next to Record a log file. For future reference, the Extra settings box in this window is where all modem initialization strings are entered. Strings entered here have a global effect on modem operation (present in all modem activity).
      
      
   4. Click OK to close. The C:\WINDOWS\MODEMLOG.TXT file is created the next time the modem is used. Review the information with Xircom Customer Support for the proper operation of the modem.
   
   Warning: Unpredictable results occur when the MODEMLOG.TXT file exceeds 2MB. To prevent this from becoming an issue, add the following line to the C:\AUTOEXEC.BAT file:
   
   
   DEL C:\WINDOWS\MODEMLOG.TXT
   
   This will delete the file each time the computer is booted preventing size issues from effecting modem operation."
   
   
4. To eliminate conflicts, verify that there are no other modems installed besides the Xircom modem. This is done by opening the Modem icon in the Control Panel. To remove the other modems select them, one at a time and click Remove.
   
   
5. Try calling a different number. Watch out for ISP dial-in numbers that are being forward to another location to extend their local calling areas. Although this can work fairly well at lower speeds, the extra connection hop(s) can degrade the signal enough to limit higher speeds, (even as compared to a direct long distance call). If this is the case, contact your BBS or ISP for a truly local dialing number for a direct dial long distance number.

• Always review the HARDWARE.TXT file in the Windows 95 directory. This file is written by Microsoft and describes machine specific problems when the software was released.
  
  
• Always review the README.TXT file in the latest Xircom Drivers disk. This file contains the latest information about the driver and any revised installation instructions that may be necessary.
  
  
• You might also contact your computer vendor for updated information with regards to the computer running in Windows 95.
  
  
• If the Infrared port is not being used, disable it in the computer's CMOS setup to resolve the COM port conflicts or to release resources that can be used by other devices. Please refer to your computer's Users Guide to make sure the port is properly disabled in CMOS. Some computers make use of a hardware setup utility that is accessed to modify BIOS settings.
  
  
• If the BIOS setup does not allow the Infrared driver to be disabled, follow the steps below to disable it in Windows 95.
  
  
  1. Right-click My Computer, and then select Properties.
     
     
  2. On the Device Manager tab, double-click Ports, select the serial or generic IR port, and then click Properties.
     
     
  3. The Device Usage window is displayed at the bottom of the General tab. In Windows 95 versions 4.00.950 or 4.00.950A remove the check from the box Exists in this hardware profile to disable the device. In Windows 95 version 4.00.950B or 4.00.950C, a check is placed in the box next to Disabled in this hardware profile to disable the device.
     
     
  4. Restart Windows 95 for the changes to take effect.
