System Setup and Boot
Basic system information regarding file, storage, security, and power configuration is
maintained in the Setup Utility held in the system ROM. The Setup Utility is accessed by
pressing the F10 key when prompted (on screen) to do so during the boot sequence. If the
screen prompt opportunity is missed, a restart will be necessary.
Failsafe Boot Block ROM
The computer comes with a reprogrammable flash system ROM (read only memory).
To upgrade the ROM, you may:
a. Order an upgraded ROMPaq diskette or CD from HP.
or
b. Download the latest ROMPaq images from the HP Web site (www.hp.com) to diskette
or CD.
All ROMPaq ROM images from HP are digitally signed to ensure authenticity and
minimize potential corruption. Your system ROM includes a Failsafe Boot Block that is
protected during the flash process and allows the computer to be restarted in the unlikely
event of an unsuccessful ROM flash.
If the system detects an invalid system ROM during the boot sequence the system will
sound one long and three short beeps, flash the three keyboard LEDs twice, and display
a recovery mode message on the screen. To recover from the Boot Block recovery mode
complete the following steps:
1. Remove any diskettes from the diskette drive or CDs from the CD drive and turn
off power.
2. Insert a ROMPaq diskette into the diskette drive or ROMPaq CD into the
CD drive.
3. Turn on power to the system.
4. If a Setup password has been established, the Caps Lock LED will come on to
prompt you for the password. Enter the password.
5. A successful boot and ROM flashing (re-programming) with a ROMPaq diskette
or CD is indicated by the three keyboard LEDs turning on and a series of beeps
rising in tone.
Security Functions
The system offers two passwords (Power-On and Setup) for system and data protection.
The passwords are independent of each other. The Power-On password, if established,
protects the computer from unauthorized access by prompting the user for a password
during power up. The Setup password, if established, protects the computer from
unauthorized or inadvertent re-configuration by prompting the user for a password prior
to entering the Setup Utility.
To establish a password:
1. Turn on or restart the computer. If you are in Windows, click Start > Shut Down >
Restart the computer.
2. As soon as the computer is turned on, press and hold the F10 key. Press Enter to
bypass the title screen, if necessary. If you do not press F10 at the appropriate
time, a restart will be necessary.
(If you are using a PS/2 keyboard, you may see a Keyboard Error message—
disregard it.)
3. Select Security, then select Setup Password or Power-On Password and follow the
instructions on the screen.
4. Before exiting, click File > Save Changes and Exit.
