System BIOS configuration 37
Loading system defaults
If the system fails after you make changes in the Setup menus, reboot the server, enter Setup, and
load the system default settings to correct the error. These default settings have been selected to
optimize the server’s performance. Setup default settings are quite demanding in terms of resource
consumption. If you are using low-speed memory chips or other types of low-performance components
and you choose to load these settings, the system might not function properly.
To load the system defaults:
1.
Reboot the server in a normal manner.
2.
During POST, press
F10
to access the Setup Utility.
3.
Press
F9
to load the default values.
4.
Press
F10
to save the changes and close the Setup Utility.
Clearing CMOS
You may need to clear the Setup configuration values (CMOS) if the configuration has been
corrupted, or if incorrect settings made in the Setup Utility have caused error messages to be
unreadable. Clearing the CMOS data removes the administrator password.
The clear CMOS setting is on clear CMOS button (SW6) on the system board. Refer to the HP DL160
G5p Server Maintenance and Service Guide for the location of this jumper block and the clear
CMOS setting.
To clear CMOS:
1.
Perform the pre-installation procedures.
2.
If necessary, remove any expansion boards, assemblies, or cables that prevent access to press
CMOS button (SW6).
3.
Locate the clear CMOS button (SW6) on the system board.
4.
Press clear CMOS button (SW6) to clear the CMOS memory.
5.
Perform the post-installation procedures.
6.
During POST, press
F10
to access the Setup Utility.
7.
Press
F9
to load the system default values.
8.
Presses
F10
to save the changes you made and close the Setup Utility.
Power-On Self Test (POST)
When the server boots up, a series of tests are displayed on the screen. This is referred to as Power-
On Self-Test (POST). POST is a series of diagnostic tests that checks firmware and assemblies to
ensure that the server is properly functioning. This diagnostic function automatically runs each time the
server is powered on.
These diagnostics, which reside in the BIOS ROM, isolate server-related logic failures and indicate the
board or component that needs to be replaced, as indicated by the error messages. Most server
hardware failures are accurately isolated during POST. The number of tests displayed depends on the
configuration of the server.
