.Sh DESCRIPTION
.Nm
allows a user or system administrator to issue commands to and otherwise
control devices which reside on standard IDE and ATA controllers.
It is used by specifying a device to manipulate,
control devices which reside on standard IDE and ATA controllers, or
the ATA bus itself.
It is used by specifying a device or bus to manipulate,
the command to perform, and any arguments the command may require.
.Sh DEVICE COMMANDS
The following commands may be used on IDE and ATA devices.
