+.Nm ida
+.Nd Compaq Intelligent Drive Array Controllers
+.Sh SYNOPSIS
+For one or more devices:
+.Cd device scbus
+.Cd device ida
+.Sh DESCRIPTION
+.Pp
+The Compaq Intelligent Drive Array (IDA) technology is used to
+distribute data across an array of hard drives.
+It unites these hard drives into one or more high-performance logical drives.
+The drive array is managed by an array controller.
+.Pp
+These controllers have the ability to provide fault tolerance for the connected
+drives and optionally provide write cache for the logical drives.
+It is also possible for an application to access the SCSI bus subsystem directly by
+using the pass-through interface.
+.Sh IMPLEMENTATION NOTES
+Extreme caution should be exercised when using the pass-through interface.
+It is possible to interfere with normal system I/O and cause hangs if
+pass-through is used to an active device.
+Pass-through should only be used to a device that is otherwise quiescent.
+.Sh COMPATIBILITY
+.Pp
+The following controllers are supported by the
+.Nm
+driver:

+.An Mike Smith Aq msith@FreeBSD.org
+.Sh BUGS
+During a
+.Fx
+install, the
+.Nm
+controller appears to correctly probe, but finds no disk devices.
+The card in question is an Intel SRCU32 RAID controller with 32Mb RAM,
+Firmware revision 2.33.01.
