BUGCHECKFATAL

   BUGCHECKFATAL enables or disables the conversion of nonfatal
   bugchecks into fatal bugchecks. The system must be rebooted on a
   fatal bugcheck. A nonfatal bugcheck places an entry only in the
   error log and deletes the corresponding process.

   This parameter should normally be OFF (0);  you should set it ON
   (1)  only when the executive is being debugged.

   Setting the SYSTEM_CHECK parameter to 1 has the effect of setting
   BUGCHECKFATAL to ON (1).

   BUGCHECKFATAL is a DYNAMIC parameter.
