    SubjectLinux, UDI and SCO.
    Hello guys,

    The stuff below is no longer a secret so I think I can share it with you.
    It does mention Linux quite a few times and may even answer someone's question
    as to whether SCO is interested at all in Linux.

    Companies Use Uniform Driver Interface to Deliver Common Device Support
    Across Multiple UNIX Operating Systems

    INTEL DEVELOPER FORUM, Palm Springs, CA (September 16, 1998) - In a move
    aimed at accelerating the growth of UNIX systems on Intel processor-based
    servers, SCO (NASDAQ:SCOC) today announced its support of Intel
    Corporation's adoption of the Uniform Driver Interface (UDI) as a standard
    device interface. In addition, Intel will work with SCO and Project UDI, to
    port UDI to the Linux operating system and distribute as freeware.

    UDI allows device drivers to be portable across both hardware platforms and
    operating systems without any changes to the driver source. This
    significantly lowers the cost of driver development, speeds time-to-market
    of new devices, and allows manufacturers to allocate development resource
    on improving device performance, features and functionality. SCO held the
    first public demonstration of this technology at SCO Forum98 last month,
    running the same driver under the SCO OpenServer, SCO UnixWare 2, UnixWare
    7, and the Hewlett-Packard HP-UX operating systems.

    UDI is a specification backed by multiple UNIX system providers, including
    Compaq, HP, IBM, NCR, SCO, and Sun Microsystems, as well as leading
    companies such as Adaptec, Interphase Corporation and Lockheed Martin. SCO
    was instrumental in proving the UDI concept and driving the formation of a
    multi-company, joint development effort to produce a prototype UDI
    environment implementation and sample drivers. This project, based on core
    code provided by SCO, resulted in working UDI implementations on seven
    different operating systems.

    "Standardization in this industry is what drives up the performance and
    innovation curves," said Ray Anderson, SCO's senior vice president,
    Marketing. "Intel's support of UDI as a standard means that all UNIX OS
    vendors can use a common device driver on all Intel platforms. SCO and
    Intel will strongly support the movement to standardize the use of UDI for
    all UNIX platforms on Intel, which we believe will generate even more
    momentum for the already exploding UNIX on Intel market."

    "Accelerating the deployment of UNIX on Intel-based servers is an important
    element in the growth of the standard high volume server model and in
    bringing price/performance advantages to the reliable, available and
    scalable benefits of UNIX," said John Miner, Intel vice president and
    general manager, Enterprise Server Group. "SCO and Project UDI have already
    made a great deal of progress in defining a common framework and Intel is
    doing its part to deliver it to the industry."

    Cost savings is among the many benefits of UDI by reducing a company's time
    and resources in developing and testing of drivers. Independent research
    firm, International Data Corporation (IDC), recognizes this as a
    substantial benefit for developers and end-users.

    "Having a standard device driver infrastructure may result in significant
    savings to end-user organizations and developers alike," said Dan
    Kusnetzky, program director for International Data Corporation's operating
    environments and serverware programs. "If an end-user organization could
    reduce the staffing required to install and maintain its server software by
    only one person, that could result in a three quarter of a million dollars
    savings over five years. If a developer was able to support a broad number
    of systems with less system testing and fewer engineers doing testing, the
    savings could stack up to be even more."

    UDI for Open Source Community
    SCO strongly supports the growth of standards-based computing and
    encouragement of open systems development. SCO, with Intel and Project UDI,
    will support the open source community by working to ensure that UDI works
    on the Linux operating system.

    Anderson continued, "The Linux and open source movements are powerful
    forces in the industry that are creating a huge resurgence in the interest
    in the UNIX System. It helps to bring the community together again and with
    UDI available on the Linux system, their developers can use the latest UNIX
    devices and peripherals on the market."

    About UDI
    UDI isolates drivers from operating system policies, as well as platform
    and I/O bus dependencies. This allows driver development to be totally
    independent of OS development. In addition, the UDI architecture insulates
    drivers from platform specifics such as byte-ordering, DMA implications,
    multi-processing, interrupt implementations and I/O bus topologies. More
    information on Project UDI is available at

    About SCO
    SCO is the world's number one provider of UNIX server operating systems,
    and the leading provider of network computing software that enables clients
    of all kinds - including, PCs, graphical terminals, NCs, and other devices
    - to have Webtop access to business-critical applications running on
    servers of all kinds. SCO designed Tarantella software, the world's first
    application broker for network computing. SCO sells and supports its
    products through a worldwide network of distributors, resellers, systems
    integrators, and OEMs. For more information, see SCO's WWW home page at: .
