# IOATAPIProtocolTransport

SCSI Protocol Driver Family for ATAPI Devices.

## Declaration

```occ
class IOATAPIProtocolTransport : IOSCSIProtocolServices
```

## Overview

Overview IOATAPIProtocolTransport contains all the bus specific support for ATAPI compliant devices. To add vendor specific features or workarounds you will sub-class the appropriate methods of this family.
