3 Server Utilities
Using the BIOS Setup Utility
This section describes the BIOS Setup Utility options, which you use to change server
configuration defaults. You can run BIOS Setup with or without an operating system
being present. Refer to “Additional Information and Software” for a link to the Technical
Product Specification where you can find details about specific BIOS setup screens.
Starting Setup
You can enter and start BIOS Setup under several conditions:
• When you turn on the server, after POST completes the memory test.
• When you have moved the CMOS jumper on the server board to the “Clear CMOS”
position (enabled).
In the two conditions listed, during the Power On Self Test (POST), you will see this
prompt:
Press <F2> to enter SETUP
In a third condition, when CMOS/NVRAM is corrupted, you will see other prompts but
not the <F2> prompt:
Warning: CMOS checksum invalid
Warning: CMOS time and date not set
In this condition, the BIOS loads default values for CMOS and attempts to boot.
If You Cannot Access Setup
If you cannot access the BIOS Setup, you might need to clear the CMOS memory. For
instructions on clearing the CMOS, see “Clearing the CMOS”.
Setup Menus
Each BIOS Setup menu page contains a number of features. Except for those features that
are provided only to display automatically configured information, each feature is
associated with a value field that contains user-selectable parameters. If a user has
adequate security rights, they can change these parameters. If a value cannot be changed
for any reason, the feature's value field is inaccessible.
