+ATA device driver control program
+.Sh SYNOPSIS
+.Nm 
+.Aq Ar command
+.Op channel [args]
+
+.Nm
+.Ic attach
+.Op channel
+.Nm
+.Ic detach
+.Op channel
+.Nm
+.Ic reinit
+.Op channel

+.Ic mode
+.Op channel
+.Op mastermode slavemode
+.Nm
+.Ic info
+.Op channel
+
+.Sh DESCRIPTION
+.Nm
+is a control program that provides the user access and control to the
+.Fx 
+ATA subsystem.
+.Pp
+.Nm
+can cause severe system crashes and loss of data if used improperly, please
+exercise caution when using this command!.
+.Pp
+.Nm
+supports the following commands:
+.Pp
+.Bl -tag -width 8n
+.It Ic attach 
+Attach an ATA channel, devices on the channel are probed and attached as
+is done on boot.
+.Pp
+.It Ic detach
+Detach an ATA channel, devices on the channel are removed from the kernel,
+and all outstanding tranfers etc are returned back to the system marked
+as failed.
+.Pp
+.It Ic reinit
+Reinitialize an ATA channel. Both devices on the channel are reset and
+initialized to the parameters the ATA driver has stored internally.
+Devices that has gone bad and no longer responds to the probe, or devices
+that has physically been removed are removed from the kernel. Likewise
+are devices that show up during a reset, probed and attached.
+.Pp
+.It Ic mode 
+Without the two mode arguments the current transfer modes of both
+devices are printed. If the mode arguments are given, the ATA driver
+is asked to change the transfer modes to those given. The ATA driver
+will reject modes that is not supported by the hardware.
+Modes are given like PIO3, udma2, udma100, case does not matter.
+.Pp
+.It Ic info
+Show info on the device on the channel, currently only the device
+name and manufacture/version strings are shown.
+.Pp
+.Sh HISTORY
+The
+.Nm
+driver first appeared in
+.Fx 5.0 .
+.Sh AUTHORS

+.Nm
+driver was written by
