Attention: Do not make changes here unless directed to do so by an IBM authorized service representative.

—Cache Control

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 the maximum system performance.

—PCI Slot/Device Information

Select this choice to view and identify system resources used by PCI devices. PCI devices automatically communicate with the server configuration information. This usually results in automatic configuration of a PCI device.

Attention: You must use the menu selections to save custom settings for the PCI Slot/Device Information choice. The save, restore and load default settings choices on the main menu of the Configuration/Setup Utility do not save the PCI Slot/Device Information settings.

PCI Device Control allows you to enable or disable the PCI slots from this menu.

–The default setting is Enable for all the PCI slots. If you select Disable, the system will not configure the disabled device and the operating system will not see the device. (This is equivalent to unplugging the device.)

—Memory Settings

Select this choice to manually disable or enable a bank of memory.

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

•Error Logs

Select this choice to view or clear error logs.

—Select POST Error Log to view the three most recent error codes and messages that the system generated during POST.

Select Clear error logs from the POST Error Log menu to clear the error log.

—Select System Event/Error Log to view the system event/error log. The system event/error log contains all the system error and warning messages that the system has generated. You can use the arrow keys to move between pages in the system event/error log.

Select Clear error logs from the System Event/Error Log menu to clear the error or event log.
