IDE(7)
IDE --
Generic IDE/ATAPI controller Subsystem
Description
The Integrated Drive Electronics (IDE) subsystem
consists of at least one IDE Host Controller card
that has at least one logical unit attached to it.
The IDE subsystem provides support
for the IDE Advanced Technology Attachment (ATA) and
the ATA Packet Interface (ATAPI) devices under
SDI for use with related target drivers.
This subsystem is accessed indirectly
by opening an appropriate target driver to access
a target device that is on an IDE controller.
It is also possible for an application to access the SCSI bus
subsystem directly by using the pass-through interface.
See
pt_open(3X).
This driver now supports Ultra DMA66 and ATAPI tape drives.

Notices
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.
