–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 the Option Installation Guide on the IBM xSeries Documentation CD. 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.

–Memory Settings

Select this choice to manually enable a pair or quad of DIMMs.

Notes:

1.A pair or quad is also known as a memory bank.

2.You cannot disable memory. Memory can only be disabled by the server.

3.For details on enabling the Hot Spare Memory feature, see the description of the Core Chipset Control menu under Advanced Setup.

If a memory error is detected during POST or memory configuration, the server can automatically disable the failing memory pair or quad and continue operating with reduced memory capacity. If this occurs, you must manually enable the memory pair or quad after the problem is corrected. Select Memory Settings from the Advanced Setup menu, and use the arrow keys to highlight the pair or quad that you want to enable; then, use the arrow keys to select Enable.

–Integrated System Management Processor Settings

Select this choice to set the server to automatically restart after a nonmaskable interrupt (NMI) occurs. The default setting for this menu item is Enabled.

v Error Logs

Select this choice to view or clear error logs.
