Under Windows NT/2K/XP you can configure the system to save a dump of physical memory when the operating system crashes. Using this crash dump facility DebugView allows you to view any debug output your kernel-mode driver made up to the time of a crash. If your driver is sufficiently instrumented with debug output, then this feature permits users that experience a crash using your driver to send you a debug output file instead of an entire memory dump. You must be capturing kernel-mode debug output with DebugView at the time of crash for this option to work.
Use the Edit|Process Crash menu item to select a crash dump file for DebugView to analyze. DebugView will process the file, looking for its debug output buffers. If it finds debug output in the crash dump DebugView will prompt you for the name of the log file where it should save the output. You can load saved output files into DebugView for viewing.
