Okay, here is a definative answer,....  The AHA-154x adapter family has been
designed so that it would co-exist with another standard hard disk controller
in the system.  The 154x adapter becomes the slave controller and allows the
standard hard disk controller to be the boot device.  No magic involved.  It
just works that way.
