Use Computer Setup (F10) Utility to do the following:
●Change factory default settings.
●Set the system date and time.
●Set, view, change, or verify the system configuration, including settings for processor, graphics,
memory, audio, storage, communications, and input devices.

Using Computer Setup (F10) Utilities
Computer Setup can be accessed only by turning the computer on or restarting the system. To access
the Computer Setup Utilities menu, complete the following steps:
1. Turn on or restart the computer.
2. As soon as the computer is turned on, press F10 when the monitor light turns green to enter
Computer Setup. Press Enter to bypass the title screen, if necessary.
NOTE: If you do not press F10 at the appropriate time, you must restart the computer and again
press F10 when the monitor light turns green to access the utility.
3. The Computer Setup Utility screen is divided into menu headings and actions.
Six menu headings appear on the Computer Setup Utility screen:
●System Information
●Main
ENWW Using Computer Setup (F10) Utilities 1

●Advanced
●Boot
●PC Health
●Exit
Use the arrow keys to select the appropriate heading, then press Enter. Use the arrow (up and
down) keys to select the option you want, then press Enter. To return to the previous screen, press
Esc.

2 Recovering the Configuration Settings
Recovering the configuration settings established in the Computer Setup (F10) Utility requires that you
first back up the settings before a recovery is needed.
The CMOS Save/Load utility can be found at http://www.hp.com under the Software & Driver Downloads
for your specific model. Download the firmware files into a folder on a removable storage device. It is
recommended that you save any modified computer configuration settings to a diskette, a USB flash
media device, or a diskette-like device (a storage device set to emulate a diskette drive) and save the
diskette or device for possible future use.
ENWW 11

Backing Up the CMOS
1. Make sure the computer to be backed up is turned on. Connect the removable storage to the
computer.
2. Boot to DOS.
3. Type N:\folder\BIOS.exe SAVE:ABC001.DAT (where Nis the drive letter of the removable
storage) to save the CMOS setting to the removable storage device.
12 Chapter 2 Recovering the Configuration Settings ENWW

Restoring the CMOS
1. Make sure the target computer is turned on. Connect the removable storage to the target computer.
2. Boot to DOS.
3. Type N:\folder\BIOS.exe LOAD:ABC001.DAT (where Nis the drive letter of the removable
storage) to load the custom CMOS setting onto the target system.
