+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for third and fourth generation DPT SCSI
+controllers.  All communication with the controllers is conducted via the
+EATA (Enhanced AT Bus Attachment) protocol (CAM committee standard
+CAM/89-004).
+.Pp
+DPT adapters examine and interpret all SCSI commands received before passing
+them to any underlying physical device(s).  In this way, caching, RAID and
+other transformations are achieved while remaining transparent to the host
+operating system.
