driver provides support for following LSI/Symbios Logic/NCR 53c8xx and
related
.Tn SCSI
controller chips:
.Pp
.Bl -dash -compact -offset indent
.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

.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.
