Cannot Start Kernel Debugger on Compaq SystemPro

 Last reviewed: May 9, 1997
Article ID: Q103568

The information in this article applies to:
  • Microsoft Windows NT operating system version 3.1
  • Microsoft Windows NT Advanced Server version 3.1

SYMPTOMS

Your Compaq SystemPro stops responding (hangs) but does not allow the kernel debugger to be started. Or, a device has an error (for example, a parity error), but cannot use IOCHK to halt the machine.

CAUSE

Compaq SystemPros do not honor the IOCHK signal on an EISA bus when they are in multiprocessor mode. Moreover, they do not have any way to successfully generate an NMI (non-maskable interrupt) when in multiprocessor mode. This means that a failing device may not be noticed, and that it is very difficult to troubleshoot a STOP message.

RESOLUTION

This is a hardware limitation. Contact Compaq Product Support for more information.
