After making changes, select:
– Save and exit the PCI Utility to save the changes and return to the
Advanced Setup choice.
– Exit the PCI Utility without saving changes to ignore the changes,
restore the previous settings, and return to the Advanced Setup choice.
You can use PCI Device Control 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 detect the device. (This is equivalent to unplugging the
device.)
— Cache Control
Select this choice to enable or disable the microprocessor cache. In addition,
you can set the microprocessor cache mode as write-back (WB) or write-
through (WT). Selecting write-back mode will provide the maximum system
performance.
— 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 can 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, and use the arrow keys to highlight
the bank that you want to enable; then, use the arrow keys to select Enable.
— Hot Swap PCI Slot Power Control
Select this choice to manually force power on to any of the six Active PCI
(hot-plug) slots. This is used for PCI adapters that do not have the presence
detect pins that the system hot-plug controller uses to turn power on to a slot.
• Event 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.
• Save Settings
