for a startable diskette in the diskette drive, then checks the hard disk drive in bay
1, and then checks a network adapter.
You also can select which PCI SCSI adapter is given boot precedence. The first
drive that is attached to the selected adapter will be assigned drive number 80L
and the operating system will start from that drive. The default for boot prece-
dence is Disabled. The range of choices depends upon the number of PCI SCSI
adapters installed in the server.
You can enable a virus-detection test that checks for changes in the master boot
record at startup. You also can choose to run POST in the enhanced mode or the
quick mode.
Select this choice to change values for advanced hardware features, such as
cache control, and PCI configuration. This choice appears only on the full Config-
uration/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 identify if the microprocessor serial number in the micro-
processor is readable.
— Core Chipset Control
Select this choice to modify settings that control features of the core chip set.
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 type as 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 infor-
mation. 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 set-
tings choices on the main menu of the Configuration/Setup Utility do not save
the PCI Slot/Device Information settings.
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.
PCI Device Control allows you to enable or disable the integrated SCSI,
video, and Ethernet controllers. You can also enable or disable PCI slots from
this menu.
– The default setting is Enable for all the controllers and 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.)
