IBM 8646 Hardware Maintenance Manual - Page 40

Select this choice to change values for advanced hardware features, such as

cache control, and PCI configuration.

A 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.

–

Processor Serial Number Access

Select this choice to specify whether the microprocessor serial number in the

microprocessor is readable.

–

System Partition Visibility

Select this choice to specify 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 the ServerGuide CDs

provided with the server for additional information on the System Partition.

–

Core Chipset Control

Select this choice to modify settings that control features of the core chip set

on the system board.

–

Cache Control

Select this choice to enable or disable the microprocessor cache. In addition,

you can define the microprocessor cache type as write-back (WB) or

write-through (WT). Selecting write-back mode provides better 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, use the arrow keys to highlight the

bank that you want to enable; then, use the arrow keys to select

Enable

.

Note:

If a memory error is detected during normal operation, System

Management Interrupt (SMI) can disable the memory.

–

PCI Bus Control

Note:

If the IBM Remote Supervisor Adapter is installed in your server, this

feature is disabled; in this case, the

PCI Bus Control

choice is not

available on the Configuration/Setup Utility menu.

Select this choice to assign IRQs and program the master latency timer.

–

PCI Slot/Device Information

Note:

This choice is available on the Configuration/Setup Utility menu only

if the IBM Remote Supervisor Adapter is installed in your server.

Select this choice to view and identify system resources that are 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 Settings

,

Restore Settings

, and

Load Default Settings

choices on the main menu of the Configuration/Setup

Utility do not save the PCI Slot/Device Information settings.
