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(S).

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.
