Select this choice to view the properties of adapters that are installed in PCI and
PCI-X slots.
Important: 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.
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 and PCI-X 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.)

Using passwords
The System Security choice appears only on the full Configuration/Setup Utility
menu. After you select this choice, you can implement two levels of password
protection: power-on password and administrator password.
Power-on password
After you set a power-on password, you can enable the Unattended Start mode.
This locks the keyboard and mouse but allows the operating system to start. The
keyboard and mouse remain locked until you type the correct password.
You can use any combination of up to seven characters (A–Z, a–z, and 0–9) for
your power-on password. Keep a record of your password in a secure place. When
a power-on password is set, POST is not completed until you type the password. If
you forget the power-on password, you can regain access to the server through one
of the following methods:
v
Type the administrator password at the power-on prompt, if an administrator
password has been set. (If necessary, see “Administrator password” on page 17
for details.) Start the Configuration/Setup Utility program, and change the
power-on password.
v Change the position of the power-on password override switch (switch 6 on
switch block 2 on the system board) to bypass the power-on password check.
You can then start the Configuration/Setup Utility program and change the
power-on password (see “Starting the Configuration/Setup Utility program” on
page 11).
