Chapter 4. Configuring the server 33
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.
