+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for following LSI/Symbios Logic/NCR 53c8xx and
+related
+.Tn SCSI
+controller chips:
+.Pp
+.Bl -dash -compact -offset indent
+.It
+53c720 and 53c770 (Fast-Wide
+.Tn SCSI )
+.It
+53c810, 53c810a and 53c815 (Fast
+.Tn SCSI )
+.It
+53c820, 53c825 and 53c825a (Fast-Wide
+.Tn SCSI )
+.It
+53c860 (Ultra
+.Tn SCSI )
+.It
+53c875 and 53c875j (Ultra-Wide
+.Tn SCSI )
+.It
+53c876 (Dual Ultra-Wide
+.Tn SCSI )
+.It
+53c885 (Ultra-Wide
+.Tn SCSI
+and
+.Tn Ethernet )
+.It
+53c895 and 53c895a (Ultra2-Wide
+.Tn SCSI )
+.It
+53c896 (PCI 64bit, dual Ultra2-Wide
+.Tn SCSI )
+.It
+53c1010 (PCI 64bit, dual Ultra3-Wide
+.Tn SCSI .
+.Em NOTE :
+at this time
+.Nm
+supports at most Ultra2-Wide with this chip)
+.It
+53c1510D (dual Ultra2-Wide
+.Tn SCSI )
+.El
+.Pp
+.Nm
+replaces the older
+.Nm ncr
+driver which supported most of these devices.
+.Pp
+Older 53C700 and 53C710 controllers are supported by the
+.Xr oosiop 4
+and
+.Xr osiop 4
+drivers, respectively.
