Information Update

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.
