PLEASE READ THE | |AGREEMENT CONTAINED IN THIS BOOK BEFORE USING THE HARDWARE PRODUCT.SEE| |IBM agreement for licensed internal code. | | | +----------------------------------------------------------------------+ You accept the terms of this Agreement(3) by your initial use of a machine that contains IBM Licensed Internal Code (called "Code"). These terms apply to Code used by certain machines IBM or your reseller specifies (called "Specific Machines"). International Business Machines Corporation or one of its subsidiaries ("IBM") owns copyrights in Code or has the right to license Code. IBM or a third party owns all copies of Code, including all copies made from them. If you are the rightful possessor of a Specific Machine, IBM grants you a license to use the Code (or any replacement IBM provides) on, or in conjunction with, only the Specific Machine for which the Code is provided. IBM licenses the Code to only one rightful possessor at a time. Under each license, IBM authorizes you to do only the following: 1. execute the Code to enable the Specific Machine to function according to its Official Published Specifications (called "Specifications"); 2. make a backup or archival copy of the Code (unless IBM makes one available for your use), provided you reproduce the copyright notice and any other legend of ownership on the copy. You may use the copy only to replace the original, when necessary; and 3. execute and display the Code as necessary to maintain the Specific Machine. You agree to acquire any replacement for, or additional copy of, Code directly from IBM in accordance with IBM's standard policies and practices. You also agree to use that Code under these terms. You may transfer possession of the Code to another party only with the transfer of the Specific Machine. If you do so, you must 1) destroy all your copies of the Code that were not provided by IBM, 2) either give the other party all your IBM-provided copies of the Code or destroy them, and 3) notify the other party of these terms. IBM licenses the other party when it accepts these terms. These terms apply to all Code you acquire from any source. Your license terminates when you no longer rightfully possess the Specific Machine. Actions you must not take You agree to use the Code only as authorized above. You must not do, for example, any of the following: 1. Otherwise copy, display, transfer, adapt, modify, or distribute the Code (electronically or otherwise), except as IBM may authorize in the Specific Machine's Specifications or in writing to you; 2. Reverse assemble, reverse compile, or otherwise translate the Code unless expressly permitted by applicable law without the possibility of contractual waiver; 3. Sublicense or assign the license for the Code; or 4. Lease the Code or any copy of it. ------------------------------------------------------------------------------- 6.0 Trademarks and service marks The following terms are trademarks of the International Business Machines Corporation in the United States,other countries, or both: AIX AS/400 Enterprise Storage Server HACMP/6000 IBM IBM logo iSeries Netfinity NetVista Operating System/400 pSeries RS/6000 Seascape SP System/360 System/370 System/390 The eServer logo TotalStorage Versatile Storage Server xSeries zSeries z/Architecture z/OS Microsoft, Windows, Windows NT, and the Windows logo are registered trademarks of Microsoft Corporation.
