CMOS backup utility
There are third-party utilities that read the CMOS settings and record them to a regular file, which can then be
backed up through normal means, or copied to an external storage media. Some of these utilities also offer the
option of restoring the CMOS settings so you need not re-enter them manually.
These utilities are not always compatible with all versions of CMOS or types of CMOS. The same applies to the
operating system version. Be sure to use a CMOS backup utility that is designed for the particular CMOS type
and OS version installed in your ProLiant server. For information on a compatible CMOS backup utility, contact
your local HP representative.
Loading system defaults
If your 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 your server’s
performance.
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 you made 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 caused error messages to be unreadable. Clearing the CMOS data
removes the administrator password.
The clear CMOS switch is switch 2 of the system configuration switch (SW2). Go to Chapter 4 of the HP ProLiant
DL140 Generation 3 Server Maintenance and Service Guide for the location of this switch.
To clear CMOS:
1. Remove the top cover.
2. If necessary, remove any expansion boards, assemblies or cables that prevent access to the system
configuration switch.
3. Locate the system configuration switch (SW2) on the system board.
4. Identify SW2-2 of the switch.
By default, SW2-2 is set to the Off position.
5. Set SW2-2 to the On position.
This will clear the CMOS memory.
6. Switch SW2-2 back to its default Off position.
7. Perform the post-installation procedure described on Chapter 2 of the HP ProLiant DL140 Generation 3
Server Maintenance and Service Guide.
8. During POST, press F10 to access the Setup Utility.
9. Press F9 to load the system default values.
10. Press F10 to save the changes you made and close the Setup Utility.
