   Warning: The following procedure changes the system registry. Incorrect changes to the registry can result in loss of data or system operation. We strongly recommend making a copy of your registry before proceeding. Please consult your Microsoft* documentation for detailed instructions for creating a registry backup.
   
   In the following registry path descriptions, HKLM refers to HKEY_LOCAL_MACHINE.
   
   
6. Start the Registry Editor:
   
   - Click Start, select Run, and type in REGEDIT.
   - Click OK
   
   Remove the following keys from the registry:
   
   HKLM\Enum\PCMCIA\Xircom-XEM5600
   HKLM\System\CurrentControlSet\Control\InstalledFiles\MDMXEM56.INF
   HKLM\System\CurrentControlSet\Control\InstalledFiles\MFXEM56.INF
   HKLM\System\CurrentControlSet\Control\InstalledFiles\NETXEM56.INF
   HKLM\System\CurrentControlSet\Control\InstalledFiles\CEM56.SYS
   
   Click on the plus sign beside the following key in the registry path:
   
   HKLM\System\CurrentControlSet\Services\Class\MultiFunction
   
   Under this key, one or more numerical keys (000x) will be displayed. Click on each of these and view the contents of the right pane of the editor to determine if the key in question is making reference to the XEM5600. If so, remove the key from the Registry. Perform this verification for each numerical key listed here. REMOVE ONLY THOSE KEYS THAT REFERENCE THE XEM5600.
   
   In a similar manner, perform the same operation for any numerical keys listed under:
   
   HKLM\System\CurrentControlSet\Services\Class\Modem
   HKLM\System\CurrentControlSet\Services\Class\Net
   
   Close the Registry Editor.
   
   
7. Shut down the computer and remove the Xircom card.
8. Open the Control Panel and double click the PC Card (PCMCIA) icon.
   a. If the PCMCIA wizard appears, follow the prompts to install PCMCIA support for your computer. Accept the default values on each screen. Restart the computer.
   b. If the PC Card Properties appears and indicates Empty - Socket 1 and Empty - Socket 2, then PCMCIA support has already been installed.
   c. Continue to XEM5600 Card Installation.

1. Start the computer WITHOUT the XEM5600 adapter inserted. Allow Windows 95 OSR2 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 XEM5600 driver files are located on the hard drive.
3. Insert the XEM5600 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 "Update Device Driver Wizard". Prior to displaying the dialog box, Windows 95 OSR2 may indicate that it is building a driver information database. If this process occurs, allow it to complete.
4. The text in the dialog box should read "This wizard will complete the installation of: Xircom PC Card XEM5600". Windows may also detect the card as a Standard PCMCIA Modem. Click Next to continue.
5. Windows 95 OSR2 will search the floppy drive for the card's driver. If the XEM5600 installation files are located in a directory on the hard drive, select the Other Location button and supply the path to this directory. If Windows still recognizes the card as a Standard PCMCIA Modem, make sure you are typing in the correct path to the driver files.
6. Once Windows 95 OSR2 indicates that it has found the driver the "Xircom Multifunction Parent", click Finish.
7. Windows 95 OSR2 should read the installation files and complete the installation of the XEM5600 adapter. During this process Windows 95 OSR2 may indicate that it is building a driver information database. It should also display successive "New Hardware Found" windows for each side of the adapter (Modem child device and Network child device). At any point during the process Windows 95 OSR2 may request additional files. If this occurs enter the path to the Windows 95 OSR2 source files. All files required for this installation reside in either the C:\WINDOWS\OPTIONS\CABS directory, the Windows 95 CD, or on the Xircom XEM5600 CD.
8. 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 XEM5600 card entries should be listed as follows:
   
   Modem:
   Modem of Xircom® 100+Modem 56
   
   Multifunction Adapters:
   Xircom® Multifunction 10/100+Modem 56 Parent
   
   Network adapters :
   Network of Xircom® 10/100+Modem 56
   
   Note: In some instances Windows* 95 OSR2 may locate the Multifunction Parent Device as a second entry in the Modem group, instead of placing it in the Multi-function Adapters group, as follows:
   
   Modem:
   Modem of Xircom® 100+Modem 56
   Xircom Multifunction 10/100+Modem 56 Parent
   
   Network adapters:
   Network of Xircom® 10/100+Modem 56
   
   In these cases there may be no Multi-function Adapters group listed. This is acceptable and will not affect the functionality of the adapter. The Multifunction Parent Device will behave exactly the same way regardless of the location of its entry in the Device Manager.
   
   
9. Execute SETUP.EXE on the Xircom CD to install the Xircom Utilities program group on the system.
   
   At the completion of the adapter installation, open the Control Panel and then double-click the Network icon. Review the clients and protocols displayed in the Network Properties box for applicability to your network. Add and configure network clients and protocols as required.
