Advanced Setup
Select this choice to change values for advanced hardware features, such as
cache control, PCI configuration, Hot Spare Memory, and Hyper-Threading
technology. This choice appears only on the full Configuration/Setup Utility main
menu.
A warning message appears above the choices on this menu to alert you that the
system might malfunction if these options are configured incorrectly. Follow the
instructions on the screen carefully.
– System Partition Visibility
Select this choice to indicate whether the System Partition is visible. To make
the System Partition visible, set this value to Visible . To make the System
Partition invisible, set this value to Hidden . See “Using the ServerGuide Setup
and Installation CD” on page 20 for additional information about the System
Partition.
– Core Chipset Control
Select this choice to modify settings that control features of the core chip set
on the system board.
To maintain optimum system operation in the event of a memory failure, you
can enable the Hot Spare Memory feature on the Core Chipset Control
menu. This feature removes the failed memory from the system configuration
and activates a Hot Spare Memory pair or quad of DIMMs to replace the
failed memory pair or quad of DIMMs. Before you can enable the Hot Spare
Memory feature, you must also install at least one additional memory pair or
quad of DIMMs and adhere to special requirements as described in “Installing
memory modules” on page 80. You can also enable the Memory Remapping
feature on the Core Chipset Control menu. To enable the Hot Spare Memory
and Memory Remapping features, change the values from No to Yes .
– CPU Options
Select this choice to enable or disable the microprocessor cache. In addition,
you can set the microprocessor cache mode to write-back (WB) or
write-through (WT). Selecting write-back mode will provide better system
performance.
– PCI Bus Control
Select this choice to view and identify system resources that are used by PCI
and PCI-X devices. PCI and PCI-X devices automatically communicate with
the server configuration information. This usually results in automatic
configuration of a PCI or PCI-X device.
After making changes, select:
- PCI MLT to assign Master Latency Timer (MLT) values for the PCI and
PCI-X devices in the server.
- PCI Interrupt Routing to assign interrupt values for the PCI and PCI-X
devices in the server.
