Using the BIOS Setup Utility
This section describes the BIOS Setup Utility options, which is used to
change server configuration defaults. You can run BIOS Setup with or
without an operating system being present.
Entering BIOS
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 above, after rebooting, you will see this
prompt:
Press <F2> to enter SETUP
In a third condition, when CMOS/NVRAM has been 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 will load default values for CMOS and
attempt to boot.
If You Cannot Access Setup
If you are not able to access 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. These parameters can be
changed if the user has adequate security rights. If a value cannot be
changed for any reason, the feature’s value field is inaccessible.
