Key Specifications
System Setup and Boot
Basic system information regarding file, storage, security, and power configuration is main-
tained in the Setup Utility held in the system ROM. The Setup Utility is accessed by pressing the
F10 key during the boot sequence. If you do not press the F10 key at the appropriate time, you
must restart the computer and press and hold the F10 key again to access the utility.
FailSafe Boot Block ROM
The FailSafe Boot Block ROM allows for system recovery in the event of a ROM flash failure.
The computer comes with a reprogrammable flash system ROM. To upgrade the ROM:
- Order an upgraded ROMPaq diskette or CD from HP, or
- Download the latest ROMPaq images from the HP Web site (
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 during an unsuccessful ROM flash.
If the computer detects an invalid system ROM during the boot sequence, the System Power
LED blinks red 8 times, 1 every second, followed by a 2 second pause. The computer also beeps
8 times. To recover from the Boot Block recovery mode complete the following steps:
1. Remove any diskettes or CDs from the drives and turn off power.
2. Insert a ROMPaq diskette or CD into the drive and turn on the computer.
3. Enter the supervisor password. If the computer successfully starts and reprograms the ROM,
the three keyboard lights will turn on, and you will hear a rising tone series of beeps.
4. Remove the diskette or CD, and then turn power off and on to restart the computer.
Security Functions
The computer offers two independent passwords for computer and data protection. The User
password protects the computer from unauthorized access by prompting the user for a password
during power up. The Supervisor password protects the computer from unauthorized or inad-
vertent reconfiguration by prompting the user for a password prior to entering Computer Setup,
You can also use the Supervisor password as an override to the User password.
To establish a User or Supervisor password:
NOTE: If the system is equipped with an embedded security device, refer to HP ProtectTools
Embedded Security Guide on the Documentation CD.
1. Turn on or restart the computer. In Windows, click Start > Shut Down > Restart.
2. As soon as the computer is turned on, press and hold the F10 key until you enter
Computer Setup. Press Enter to bypass the title screen, if necessary.
3. Select either Set Supervisor Password or Set User Password and enter the password.
4. To save the password and exit Computer Setup, click File > Save Changes and Exit.
