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 as soon as the computer is turned on. 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).

NOTE: No USB device of any type will function during bootblock recovery.

To upgrade the ROM, you may:

a. Order an upgraded ROMPaq diskette from HP.

or

b. Download the latest ROMPaq images from the HP Web site (www.hp.com).

All ROM images used with HPQFlash and SSM are digitally signed to ensure authenticity and

mini-mize potential corruption. Your system ROM includes a Failsafe Boot Block that is pro-

tected 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 and turn off power.

2. Insert a ROMPaq diskette into the diskette drive or a bootable CDROM into an IDE CD-ROM

drive. (Bootable ISO CDs are available on the Web at www.hp.com.)

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 is

indicated by the three keyboard LEDs turning on and a series of beeps rising in tone.

Security Functions

The system offers independent Power-On and Setup passwords for system and data protection.

The Power-On password protects the computer from unauthorized access by prompting the user

for a password during power up. The Setup password protects the computer from unauthorized

or inadvertent re-configuration of legacy device resource settings or ROM flash upgrade 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

F10

until you enter Computer

Setup. Press Enter to bypass the title screen, if necessary. If you do not press

F10

as soon as the computer starts, a restart will be necessary.
