## SYMPTOMS

After you upgrade to Windows NT version 3.5 with any of the Intelligent Digiboard adapters, more than one of the following events may appear in the Event Viewer:

Event ID: 4103 Source: ntxall Type: Information
Description: Overriding current configuration to use 8K memory mapped window on ntxall<a>.

Event ID: 25 Source: Serial Type: Error
Description: User configuration for parameter ntxall<a>Line<b> Concentrator<c>Port<d> must have PortAddress.
where: <a> is order number of installed adapters in Windows NT (usually 2 if a network adapter was installed first on this computer) <b> is the line number used on the Digiboard adapter (usually 1) <c> is the concentrator number used on the Digiboard adapter (usually 1) <d> is the number of each port configured on the Digiboard adapter.

## CAUSE

The ntxall subkey in the Windows NT Registry should reside under the Services subkey of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet for all intelligent Digiboard adapters. Any subkeys residing under the Parameters subkey of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Serial are port configurations for non-intelligent Digiboard adapters and any additional communication ports. This problem occurs after the upgrade process where a copy of the ntxall subkey tree was placed under the Parameters subkey.

## RESOLUTION

To prevent these events from appearing in the Event Viewer, modify the Windows NT Registry.
WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.

1. Start REGEDT32.EXE and locate the following Registry subkey:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet \Services\Serial\Parameters
2. Remove all subkeys below and including ntxall<a>.
3. Exit the Registry Editor.
4. Shut down and restart Windows NT.
