WARNING: The following step involves making modifications to the
system Registry. The instructions here should be followed exactly,
and you should read them through before beginning. Manually making
incorrect modifications to the Registry could cause your system to
malfunction. If you are unsure about working with the Registry, we
recommend that you consult your Microsoft documentation for
clarification regarding Registry terminology and use of the
Registry editor. It is also recommended that you back up the
Registry before proceeding.
In the following registry path descriptions, HKLM refers to the
HKEY_LOCAL_MACHINE key.
6. Start the registry editor (Start, Run, type Regedit, and click
OK). Remove from the registry:
HKLM\Enum\PCMCIA\Xircom-CreditCard_Ethernet_10/100_+_Modem_56...
HKLM\System\CurrentControlSet\Control\InstalledFiles\MDMCEM56.INF
\MFCEM56.INF
\NETCEM56.INF
\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 CEM56 adapter. If so, remove the key from
the Registry. Perform this verification for each numerical key
listed here. REMOVE ONLY THOSE KEYS THAT REFERENCE THE CEM56
ADAPTER.
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 then restart it.
8. You are now ready to re-install the CEM56 with the new driver
release.
