BUG: Debug Kernel Ignores Fatal Exits When OutputTo=

 * }

Q111597

-

The information in this article applies to:


 * Microsoft Windows Software Development Kit (SDK) 3.1

-

SYMPTOMS
By default, the Windows debugging kernel sends its debug messages to the AUX device (which maps to the COM1 port). When the debug output from the Windows kernel is redirected by using OutputTo=NUL or OutputTo= in the [DEBUG] section of the SYSTEM.INI file, Fatal Exit messages are ignored automatically.

RESOLUTION
This behavior is by design of the Windows debugging kernel and there is no other flag to control the output of Fatal Exit messages even if you have a serial terminal connected to the COM1 or COM2 port.

STATUS
Microsoft has confirmed this to be a bug in Windows version 3.1. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
