Failsafe Boot Block ROM

The computer comes with a reprogrammable flash system ROM (read only memory). To
upgrade the ROM, download the latest ROM BIOS image from the HP Web site (www.hp.com)
and follow the online GUI/instructions.

All ROM BIOS 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 search for
a bootable device. To recover from the Boot Block recovery mode complete the following steps:

Boot Block Recovery

1. Remove any bootable media from the computer and turn off power.

2. Insert a bootable diskette, or CD containing the ROM BIOS.

3. Turn on power to the system.

4. The system will automatically flash the ROM, load the BIOS default, and then boot to the
operating system.

Security Functions

The system offers a single supervisor password for system and data protection.
The password, if established, protects the computer from unauthorized access by prompting the
user for a password during power up. The 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.

Establishing a password:

1. Turn on or restart the computer. If you are in Windows, click Start > Shut Down >
Restart the computer.

2. When the F10 Setup message appears in the lower-right corner of the screen, press the
F10 key. Press Enter to bypass the title screen, if necessary. If you do not press F10 when
prompted, a restart will be necessary.

3. Select Password Option, then select Change Supervisor Password and follow the
instructions on the screen. You may also want to establish the Password check at this time.
This will allow you to specify when the password will be required.

4. Before exiting, click File > Save Changes and Exit.

Changing a password:

1. Turn on or restart the computer. If you are in Windows, click Start > Shut Down > Restart
the Computer. To change the setup password, run Computer Setup.

2. When the key icon appears, type your current password, a slash (/) or alternate de-limiter
character, your new password, another slash (/) or alternate delimiter character, and your
new password again as shown:

current password/new password/new password.

NOTE: Type the new password carefully since the actual characters do not appear on the
screen.

3. Press the enter key.

The new password will take effect the next time the computer is restarted.

Deleting a password

1. Turn on or restart the computer. If you are in Windows, click Start > Shut Down > Restart
the Computer. To delete the setup password, run Computer Setup (F10).

2. When the key icon appears, type your current password followed by a slash (/) or alternate
delimiter character as shown. Example: currentpassword/

3. Press the Enter key.

Clearing CMOS

1. Shut down the system and disconnect the power cord from the power outlet.

2. Remove the chassis access panel.

3. On the system board, move the CMOS jumper from pins 2-3 to pins 1-2

4. Allow the jumper to remain in that position for at least 5 seconds then, return the jumper
to pins 2-3.

5. Replace the chassis access panel and reconnect the power cord.

6. Turn on the computer and allow it to start.
