 .Sh DESCRIPTION
-This driver provides access to SCSI devices connected to an Adaptec 
-174x hostadapter in either Standard or Enhanced Mode. If the controller
-is set to Standard mode (by the ECU), the driver will automatically 
-switch the card to Enhanced mode during the device probe.
-.sp
-Please note that the above implies that when you are configuring a system
-with both aha and ahb drivers, the ahb driver should be listed first in the
-kernel config file. This ensures that the ahb driver will find the Adaptec 174x
-boards before the aha driver probes for Adaptec 154x boards.
-.sp
+This driver provides access to the
+.Tn SCSI
+bus connected to an Adaptec 
+174x hostadapter in either 
+.Dq Em standard
+or
+.Dq Em enhanced
+mode. If the controller
+is set to standard mode (using the
+.Tn EISA
+configuration utility),
+the driver will automatically 
+switch the card to enhanced mode during the device probe.
+.Pp
+.Sy N.B. :
+When configuring a system
+with both
+.Xr aha 4
+and
+.Nm
+drivers, the
+.Nm
+driver should be listed first in the kernel configuration file.  This
+ensures that the
+.Nm
+driver will find the Adaptec 174x boards before the 
+.Xr aha 4
+driver probes for Adaptec 154x boards.
+.Pp
 Note that no I/O addresses are configured in the kernel config file. The
-174x uses EISA slot specific I/O which is configured automatically.
