SCO and the Uniform Driver Interface (UDI)
The SCO Group, Inc. (SCO) is advancing the state of the art in
device driver technology.
As an active member of Project UDI, the industry group that designed
UDI (the Uniform Driver Interface), SCO has worked jointly with a number
of system vendors and IHVs, including Adaptec, Compaq, Hewlett-Packard,
IBM, Intel, Interphase, Lockheed Martin, SBS Technologies, STG, Sun
Microsystems and Unisys, to define and promote a
cross-vendor, cross-platform device driver interface.
UDI support and development kit are provide with SCO UnixWare operating
system starting with UnixWare 7.1.2 (also known as OpenUNIX 8.0.0)
and OpenServer 5.0.7.
The udienv package provides UDI support and the udidk
package provides the UDK development kit.
These products are based on the final review draft of the 1.01 UDI
The UDI 1.01 specification set is available from
Project UDI .
UDI is a device driver interface that allows one driver to be run on a
variety of operating systems. A driver that is coded to the UDI
specification can run on any operating system for which UDI support is
available; it will no longer need to be rewritten to use each
system's specific set of functions and structures. A driver coded to
UDI would use UDI interfaces rather than DDI, SDI, MDI or other
proprietary OS interfaces. Generally, though,
the same functionality, or a superset, is available in UDI.
Implementations of the UDI environment have been demonstrated on UnixWare 7,
OpenServer 5, OpenServer 6, and UnixWare 2.1, along with operating systems from
other vendors. See the Project UDI web site for a complete list.
UDI support will be included in all SCO operating systems, including
OpenServer 5, OpenServer 6, and UnixWare 7.
