+.Sh NAME
+.Nm osiop
+.Nd Symbios/NCR 53C710 SCSI driver
+.Sh SYNOPSIS
+.Cd "osiop* at gsc? irq 9                  " Pq "hppa"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the
+.Tn Symbios/NCR
+53C710
+.Tn SCSI
+controller chip.
+.Pp
+The
+.Tn Symbios/NCR
+53C700
+.Tn SCSI
+controller is handled by the
+.Xr oosiop 4
+driver, while the
+.Tn Symbios/NCR
+53C8xx
+.Tn PCI
+.Tn SCSI
+host adapters are handled by the
+.Xr siop 4
+driver.
+.Sh CONFIGURATION
+The
+.Nm
+driver supports the following
+.Sy flags
+for use in
+.Xr config 8
+files:
+.Pp
+.Bl -tag -compact -width "bits 8-15:"
+.It bits 0-7 :
+disable disconnect/reselect for the corresponding
+.Tn SCSI
+target
+.It bits 8-15 :
+disable synchronous negotiation for
+.Tn SCSI
+target
+.It bits 16 :
+disable DMA interrupts
+.El
+.Pp
+.Qq Target
+is synonymous with
+.Tn SCSI
+ID number.
+.Pp
+Note that
+.Tn SCSI
+tape drives should be allowed to perform disconnect/reselect or performance
+will suffer.
