1. Open the System Editor (Start, Run, type SYSEDIT, and click OK).
2. Select the CONFIG.SYS file either by clicking on the CONFIG.SYS title bar or by selecting Window (on the Toolbar) and then selecting CONFIG.SYS from the displayed list.
3. Select Search from the Toolbar, click Find and type EMM386 in the dialog box, click Find Now. If found, change the EMM386 line to read as follows:
   
   DEVICE=C:\WINDOWS\EMM386.EXE NOEMS
   
   
4. Select the SYSTEM.INI file either by clicking on the SYSTEM.INI Title Bar or by selecting Window (on the Toolbar) and selecting SYSTEM.INI from the displayed list.
5. Select Search from the Toolbar, click Find and type EMMEXECLUDE in the Dialog box and click Find Now. If found modify the line to read as follows:

   Only one EMMEXCLUDE statement should be present. If there are additional statements of this type present they should be commented (by placing a semicolon at the beginning of the line) or deleted. If the EMMEXCLUDE line is not present then add the above line to the [386Enh] section as follows:
   
   SYSTEM.INI:
   [386Enh]
   EMMEXCLUDE=C000-CFFF (use C000-CBFF on Cardbus computers)
6. Save all files and exit the System Editor.

1. Start the computer WITHOUT the CEM56-100/REM56G-100 card inserted. Allow Windows 95 to boot fully.
2. Place the Xircom CD into the CD-ROM drive or be sure that you know the full path to the directory where the CEM56-100/REM56G-100 driver files are located on the hard drive.
3. Insert the CEM56-100/REM56G-100 into the computer's PC Card slot. Windows will automatically detect the presence of the card and indicate that it has found new hardware by displaying a dialog box entitled "New Hardware Found." Prior to displaying the dialog box, Windows 95 may indicate that it is building a driver information database. If this process occurs, allow it to complete.
4. In the New Hardware Detected window the selection "Driver from disk provided from manufacturer" should be selected, if not choose this option and click OK.
5. In the box labeled "Copy manufacturer's files from:", enter the path to the directory where the CEM56-100/REM56G-100 installation files are located. The default path shown is A:\. The Xircom file it is looking for is MFCEM56-100.INF.
6. Windows 95 should read the installation files and complete the installation of the CEM56-100/REM56G-100 card. During this process Windows 95 may indicate that it is building a driver information database. It should also display successive "New Hardware Found" windows for each side of the card (Modem child device and Network child device). At any point during the process Windows 95 may request additional files. If this occurs enter the path to the Windows 95 source files. All files required for this installation reside in either the C:\WINDOWS\OPTIONS\CABS directory, the Windows 95 CD, or on the CEM56-100/REM56G-100 CD. Restart if prompted.
7. When the installation process has completed go to the Windows 95 Device Manager to verify the installation. This can be reached by doing the following: - Click Start, select Settings, and then click Control Panel.
   - Double-click the System icon in Control Panel
   - In System Properties, select the Device Manager tab.
   
   The CEM56-100/REM56G-100 entries should be listed as follows:

   Network adapters:
   Network of Xircom CreditCard Ethernet 10/100+Modem 56
   
   
8. Execute SETUP.EXE on the Xircom CD to install the Xircom Utilities program group on the system.
   
   At the completion of the PC Card installation, open the Control Panel and then double-click the Network icon. Review the clients, protocols and services displayed in the Network Properties window for applicability to your network, and adjust as necessary.
