+.Sh NAME
+.Nm aacraid
+.Nd Adaptec AACRAID Controller driver
+.Sh SYNOPSIS
+To compile this driver into the kernel,
+place the following lines in your
+kernel configuration file:
+.Bd -ragged -offset indent
+.Cd device pci
+.Cd device aacraid
+.Pp
+To compile in debugging code:
+.Cd options AACRAID_DEBUG=N
+.Ed
+.Pp
+Alternatively, to load the driver as a
+module at boot time, place the following line in
+.Xr loader.conf 5 :
+.Bd -literal -offset indent
+aacraid_load="YES"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the Adaptec by PMC RAID controllers,
+including Series 6/7/8 and upcoming families.
+.Pp
+The RAID containers are handled via the
+.Nm aacraidp0
+bus.
+The physical buses are represented by the
+.Nm aacraidp?
+devices (beginning with aacraidp1). These devices enable the
+SCSI pass-thru interface and allows devices connected
+to the card such as CD-ROMs to be available via the CAM
+.Xr scsi 4
+subsystem.
+Note that not all cards allow this interface to be enabled.
+.Pp
+The
+.Pa /dev/aacraid?
+device nodes provide access to the management interface of the controller.
+One node exists per installed card.
+If the kernel is compiled with the
+.Dv COMPAT_LINUX
+option, or the
+.Pa aacraid_linux.ko
+and
+.Pa linux.ko
+modules are loaded, the
+Linux-compatible
+.Xr ioctl 2
+interface for the management device will be enabled and will allow
+Linux-based management applications to control the card.
+.Sh HARDWARE
+Controllers supported by the
+.Nm
+driver include:

+.Sh DIAGNOSTICS
+Compiling with
+.Dv AACRAID_DEBUG
+set to a number between 0 and 3
+will enable increasingly verbose debug messages.
+.Pp
+The adapter can send status and alert messages asynchronously
+to the driver.
+These messages are printed on the system console,
+and are also queued for retrieval by a management application.
