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); set it ON (1) only
    when the executive is being debugged or if so instructed by VSI.

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

    BUGCHECKFATAL is a DYNAMIC parameter.
