If the
Boot Fail Count
choice is enabled, you must restart the system three times
to restore the system BIOS default settings. If this choice is disabled, the system
BIOS defaults can be restored only from the Configuration/Setup Utility main
menu.
You can enable a virus-detection test that checks for changes in the master boot
record at startup.
•
Advanced Setup
Select this choice to change values for advanced hardware features, such as
cache control and PCI configuration. This choice appears only on the full
Configuration/Setup Utility main menu.
A warning 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

Partition invisible, set this value to
Hidden

Core Chipset Control
Select this choice to modify settings that control features of the core chip set
on the system board.
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 define the microprocessor cache mode as write-back (WB) or write-
through (WT). Selecting write-back mode provides better system
performance.
—
PCI Slot/Device Information
Select this choice to view and identify system resources that are used by PCI
devices. PCI devices automatically communicate with the appliance 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.
Use the
PCI Device Control
choice 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.)
