Refer to the Implementing Microsoft Windows Server 2003 with Service Pack 1 with ProLiant servers integration note for details. Table 7. Known issues Issue 1 The Microsoft IPMI driver will not install on HP ProLiant servers. Description The Microsoft IPMI driver fails to load on HP ProLiant servers. For additional information and a link to the hotfix that resolves this issue, refer to Microsoft Knowledge Base Article 912134 (http://support.microsoft.com/?kbid=912134). Issue 2 Solution Download and install the hotfix from Microsoft, as instructed in Microsoft Knowledge Base Article 912134. SYSTEM ROM UPGRADE REQUIRED on ProLiant servers with Intel Xeon, Xeon DP, or Xeon MP processors to correct timing marginality in the Instruction Decoder. Description Intel Corp. has identified a timing marginality in a small percentage of Intel Xeon, Intel Xeon DP and Intel Xeon MP Processors that can cause erratic system behavior after prolonged usage. Based on Erratum P72 in the Intel Xeon Processor Specification Update and Erratum O69 in the Intel Xeon MP Processor Specification Update dated July 2004, the timing marginality in the instruction decoder unit may cause unpredictable application or system behavior. For additional details, refer to the customer advisory located at http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=P SD_EL040709_CW01. Solution This timing marginality in Intel Xeon, Intel Xeon DP and Intel Xeon MP Processors is corrected in the June 2004 System ROMs. However, separate Intel errata (Erratum P76 and Erratum O73 - A Timing Marginality in the Arithmetic Logic Unit May Cause Indeterminate Behavior) has been corrected in System ROMs dated September 2004. System ROMs dated September 2004 include the microcode required to correct BOTH errata P72 and P76 in the Xeon Processor and errata O69 and O73 in the Xeon MP Processor. HP strongly recommends downloading and applying the System ROMPaq Upgrade Diskette (dated September 2004 or later) to upgrade the ProLiant System ROM to the appropriate date. 15
