Slide 2

Announcing the creation of…

A new organization in SCO with the charter to create new licensing programs for our

UNIX intellectual property

Slide 3

SCO’s History

The invention of UNIX at Bell Labs

SCO establishes UNIX on Intel

Unix Systems Laboratories source code and UnixWare acquired by SCO

in 1995

Merges with SCO in 2001

Develops UNIX derivatives Xenix, OpenServer, bringing UNIX

to the Intel volume market and setting the stage for Linux

1994Caldera established to develop

commercial Linux distribution

1979

1969

2003 SCO establishes SCOsource

Slide 4

Why license SCO’s Intellectual Property?

Customers are requesting it

Increase shareholder value through existing IP

Strengthen Linux by licensing value-add IP

Increase UNIX application use on Linux

Slide 5

First Deliverable

SCO’s UNIX Shared Libraries from for use with Linux Already in use among many enterprise customers Already encouraged by many Linux vendors Increases the number of UNIX applications available to Linux

Upcoming Plans for SCOsource

SCO System V for Linux

Slide 9

UNIX application details: Object File Formats

There are two object file formats that have been used in UNIX COFF: original format (SVR2, SVR3, SVR4) ELF: improved format introduced around 1990

Early versions of SCO UNIX (3.2v4.2, OpenDesktop, etc) used COFF only

OpenServer supports both COFF and ELF UnixWare supports only ELF Linux native mode is also ELF

Slide 10

UNIX application details: Library Usage

Libraries must match object file format of application (COFF or ELF)

ELF libraries are dynamically linked COFF libraries may be statically linked UNIX applications can be created to use shared system

libraries or to incorporate the libraries they need (self-contained)

Standard practice is to use shared libraries Reduces application size on disk Reduces overall system memory usage Allows library maintenance to be de-coupled from app

Slide 11

SCO System V for Linux Release 1SCO UNIX Runtime Libraries

First release includes COFF static shared libraries from OpenServer

Compatible with SCO UNIX, OpenDesktop, all versions of OpenServer

Packaged as an rpm installable on Linux License required and enforced (at install time) on

non-SCO Linux systems

Slide 12

Customer benefits

Preserves investment in legacy applications Application licenses End user training Applications integration

Same application runs on UNIX and Linux Allows migration of applications to Linux even if

source is not available Permits movement to Linux without requiring

simultaneous upgrade or conversion of apps Cost effective evaluation of Linux in production

environment

Slide 13

Why start with OpenServer COFF static libraries?

Most customer interest (some large accounts) Linux ABI Project interest/development

focussed on SCO COFF applications Largest base of applications for SCO platforms Oldest legacy applications

Probably not the ISV’s latest release Upgrade to Linux versions would be painful Source code may not be available Nonetheless, apps may be firmly entrenched in

customers business practice

Slide 14

What about UnixWare Libraries?

Next step is to investigate value and feasibility Customer demand?

UnixWare apps are newer, more likely to get ported? More compatible with Linux versions?

Confirm Linux ABI functionality Not much discussion in Linux ABI project

UnixWare libraries are a much larger set than the COFF static libraries

Need to test some applications

Slide 15

Availability & Delivery

Customer Pricing: $149 per processor

Volume pricing available at standard SCO discounts

SCO Linux Server 4.0 includes a SCO System V for Linux license at no charge via SCO Update

Delivery is via Download Only

SCO Supports the SSVL

Support for the Linux ABI is same as any other Linux feature

Slide 16

Obtaining SCO System V for Linux

SCO Linux Customers Registered SCO Linux customer will be notified of

availability of ssvl via email Available via SCO Linux Update service Two step process (run from shell as root):

run “apt-get update” (updates the apt database) run “apt-get install ssvl” (downloads and installs ssvl)

ssvl rpm will silently install (it verifies that it is being installed on a SCO Linux system)

Slide 17

Summary: SCO System V for Linux

License for SCO OpenServer Libraries on Linux Aimed at current users of SCO UNIX applications Key message is investment preservation Free value add for SCO Linux users Available for non-SCO Linux distributions Enables solution migration opportunities
