Record your BIOS setup settings. If default values ever need restoring (after a CMOS clear, for example), you must run BIOS setup again. Your record will make this much easier. If BIOS Setup is Inaccessible If you are not able to access BIOS setup, you might need to clear the CMOS memory. Clear CMOS by pressing the reset button and hold it down for five seconds or more, and then, while holding the reset button down, press the power button for five seconds. Release both buttons at the same time. Starting BIOS 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 performed a CMOS clear (press reset and power buttons as described above). Under either of these two conditions, after rebooting, you will see this prompt: Press to enter SETUP • Under a third condition, when CMOS/NVRAM has been corrupted, you will see other messages 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. BIOS Setup Menus Each BIOS setup menu page contains a number of features. Except those used for information purposes, each feature is associated with a value field that contains user-selectable parameters. Parameters may be changed depending upon the security option chosen. If a value is not changeable due to insufficient security privileges (or other reasons), the feature's value field becomes inaccessible. The bottom portion of the BIOS Setup screen provides a list of commands that are used for navigating the setup utility. Table 4-6.

the actual hardware do not agree, POST generates an error message.
Record your BIOS setup settings. If default values ever need restoring (after a CMOS clear, for example),
you must run BIOS setup again. Your record will make this much easier.
If BIOS Setup is Inaccessible
If you are not able to access BIOS setup, you might need to clear the CMOS memory. Clear CMOS by
pressing the reset button and hold it down for five seconds or more, and then, while holding the reset button
down, press the power button for five seconds. Release both buttons at the same time.
Starting BIOS 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 performed a CMOS clear (press reset and power buttons as described above).
Under either of these two conditions, after rebooting, you will see this prompt:
Press <F2> to enter SETUP
•
Under a third condition, when CMOS/NVRAM
has been corrupted, you will see other messages 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.
BIOS Setup Menus
Each BIOS setup menu page contains a number of features. Except those used for information purposes,
each feature is associated with a value field that contains user-selectable parameters. Parameters may be
changed depending upon the security option chosen. If a value is not changeable due to insufficient security
privileges (or other reasons), the feature’s value field becomes inaccessible.
The bottom portion of the BIOS Setup screen provides a list of commands that are used for navigating the
setup utility.
