void onabrt(int sig)
{
  static int count;

  if (++count == 2) reboot(RBT_HALT);
  gotabrt = 1;
}

     Reboot() is used  to  close  down  the  system.   It  allows
     several ways of shutting down depending on how:

     reboot(RBT_HALT)
          Halt the system and return to the monitor prompt.

     reboot(RBT_REBOOT)
          Reboot the system by letting the  monitor  execute  the
          "boot" command.

     reboot(RBT_PANIC)
          Cause a system panic.  This is not normally  done  from
          user  mode, but by servers using the sys_abort() kernel
          call.

     reboot(RBT_MONITOR, code, length)
          Halt the system and let the monitor execute  the  given
          code  of the given length.  (code is of type char * and
          length of type size_t.)

     reboot(RBT_RESET)
          Reboot the system with a hardware reset.
