Set to true, at the end of normal drive detection, COM ports 1-7 (in reverse order) will be scanned for a connection to a serial drive server. This option provides flexibility with the COM port and baud rate to be used, it need not be configured ahead of time, but at the expense of a slower boot process. Even when set to false, this functionality can still be invoked by holding down the ALT key at the end of normal drive detection.
