The UDI SCSI Driver Specification defines the required interfaces and semantics for UDI environments that support SCSI Drivers. This is an optional extension to the UDI Core Specification, which is defined in a separate book. See the Document Organization chapter in the UDI Core Specification for a description of the other books in the UDI Specification, as well as references to additional tutorial materials. The intended audience for this book includes driver writers, environment implementors, and metalanguage implementors.

Countless people have helped in one way or another and any omissions or errors on our part in the list above are just that: omissions or errors on our part.

Thanks to Kevin Quick and the folks at Interphase for hosting the Interoperability events which have provided a great venue for validating both prototype and production UDI products.

Finally, thanks to David Roberts (Certek Software Designs) for designing the Project UDI logo.
