.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provies support for the NCR 53c94-based scsi host adaptor
|
|
adaptor on the Decstation 5000 series, and for the PMAZ-AA and related
|
|
TurboChannel SCSI-adaptor option boards.
|
|
The
|
|
.Nm
|
|
is a medium-performance implementation of the SCSI-I common set
|
|
supporting synchronous and asychronous SCSI devices. The driver
|
|
provides no support for targets with multiple logical unit numbers
|
|
(LUNs).

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
driver first appeared in
|
|
.Bx 4.4 .
|
|
.Sh BUGS
|
|
The
|
|
.Nm
|
|
driver only supports the
|
|
.Nm oldscsibus
|
|
higher-level layer, and the
|
|
.Nm rz
|
|
and
|
|
.Nm tz
|
|
devices, which first appeared in
|
|
.Bx 4.4 /pmax.
|
|
It should be re-written to support the
|
|
.Nm scsibus
|
|
machine-independent higher-level SCSI layer and the
|
|
.Nm sd ,
|
|
.Nm st ,
|
|
and
|
|
.Nm cd
|
|
drivers. This is
