How to generate a complete or kernel crash dump file by using NMI switch in Windows 2000 Server
Important This article contains information about how to modify the registry. Make sure that you back up the registry before you modify it. Make sure that you know how to restore the registry if a problem occurs. For more information about how to back up, restore, and modify the registry, click the following article number to view the article in the Microsoft Knowledge Base: 322756 (http://support.microsoft.com/kb/322756/) How to back up and restore the registry in Windows XP and Windows Vista INTRODUCTIONSometimes, when you use the CTRL+SCROLL LOCK+SCROLL LOCK keyboard shortcut to generate a crash dump file, the operation might not function correctly. This shortcut may be useful in debugging the cause of a server that has stopped responding (hangs) when typical live debugging is not possible.

How to generate a memory dump file when a server stops responding (hangs)
However, Hewlett Packard (HP) BladeSystem servers from the Hewlett-Packard Development Company are managed by using a browser-based graphical user interface (GUI). A keyboard is not attached to the HP BladeSystem server. Therefore, you cannot use this keyboard shortcut to generate a crash dump file. In these cases, you must generate a complete or kernel crash dump file by using the Non-Maskable Interrupt (NMI) switch that causes an NMI on the system processor. This article describes how to generate a complete or kernel crash dump file by using an NMI switch.Note Use this method to generate complete memory dump files with caution. Ideally, you should only do this only when you are explicitly requested to by the Microsoft Customer Support Services Engineer. Any kernel or complete memory dump file debugging should be the last resort when all the typical methods of troubleshooting have been completely exhausted. MORE INFORMATIONWarning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk. Before you continue, look in the hardware BIOS reference manual or contact your hardware vendor to determine whether the server is equipped with an NMI switch. To enable complete memory dump files on your server, follow these steps:
