A system dump may created by any of the following means:

• Manually by using the command sequence:

  Ctrl-Alt-F10-F10 or Ctrl-Alt-Numlock-Numlock

  
  Automatically when an application or system trap occurs. See the description of the TRAPDUMP CONFIG.SYS setting for details.
  
  Directly from an application program by using the DosForceSystemDump API.
  
  Directly from a physical device driver by calling the VectorSDF address returned by the DevHlp_GetDOSVar helper service.
  
  Under the kernel debugger from the debug console by giving control to the RASRST routine. See Forcing a System Dump From the Kernel Debugger for further details.

  Note:

  Whilst it can be advantageous to take a dump when the system trace is active, it is not a pre-requisite. Occasionally system trace has been found to caused other traps.
