PCIe Slot Update Following are updates to information provided in the Hardware Owner's Manual about the PCIe slots on the riser boards. • Figure 6-5 incorrectly specifies slot 2 as having a x8 lane width. Although the physical connector is x8, the actual PCI-e lane width of slot 2 is x4. • Figure 6-6 specifies slot 3 as having a x8 lane width. This is correct, however full x8 performance on this slot is application-dependent. To ensure full x8 performance where needed, use slot 1 or slot 4 for add-in cards requiring x8 operation. System Setup Program Updates CPU Information Screen If you are running Red Hat® Enterprise Linux® version 5 operating system on a system containing one or two quad-core AMD® processors, disable the Demand-Based Power Management option. The system can hang during shutdown if the option is enabled. This issue will be fixed in a future update release from Red Hat. Memory Information Screen The Low-Power Mode option has been removed from the Memory Information screen. Integrated Devices Screen Microsoft® Windows Server® 2008 supports the OS Watchdog Timer option in the Integrated Devices screen of the System Setup program, but Windows Server 2003 does not. Windows Server 2003 does not support the WDAT implementation of the Advanced Configuration and Power Interface (ACPI) 3.0b specification that is required for the OS Watchdog Timer option. System Security Screen TPM is not supported on Microsoft Windows Server 2003. Ensure that the TPM Security option is disabled on the System Security screen when running Windows Server 2003 on your system. Information Update 5
