System Setup and Boot
Basic system information regarding system information, setup, power management, hardware,
and passwords 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.

Check that the memory modules have
been installed correctly and that proper
modules are used.
For systems with a graphics card:
1. Reseat the graphics card. Power on the
system.
2. Replace the graphics card.
3. Replace the system board.
For systems with integrated graphics,
replace the system board.
1. Upgrade the BIOS to proper version.
2. Change the processor.
1. Check cable connections.
2. Run the Computer Setup utility and
ensure the device port is enabled.
using and use the correct media type.
2. Replace the diskette or CD with a new
one.
Upgrade the BIOS to proper version.
1. Verify the correct ROM.
2. Flash the ROM if needed.
3. If an expansion board was recently
added, remove it to see if the problem
remains.
4. Clear CMOS.
5. If the message disappears, there may be
a problem with the expansion card.
Replace the system board.
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 instructions.
The 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 Failsafe Boot Block
attempts to locate a valid BIOS image on removable media.
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 flash drive or CD containing the ROM BIOS.
3. Turn on power to the system.
4. The system will automatically flash the ROM. After a successful flash, the system will either
automatically restart of prompt the user to unplug the unit, wait 5 seconds, reattach the power
cord, then press the power button.
Password Security
General Information
• A supervisor password must be set before a user password.
• If both the supervisor and user passwords are activated and the correct supervisor password
is entered, all read/write options can be modified.
• If both the supervisor and user passwords are activated and the correct user password is
entered, all options that cannot be modified must be displayed as read-only.
To clear a password using system board jumpers
1. Shut down the computer and disconnect the power cord from it power source.
2. Move the CLR_PSWD jumper from pins 1 and 2 and place it on pins 2 and 3.
3. Reconnect the power cord to the power source and start the computer.
4. Shut down the computer a second time and disconnect the power cord from it power source.
5. Move the CLR_PSWD jumper from pins 2 and 3 and place it on pins 1 and 2.
6. Reconnect the power cord to the power source and start the computer.
Clearing CMOS
To clear CMOS using F10 Computer Setup
Enter F10 Computer Setup and press F5. This will reset all BIOS setup options to their default
values.
This will not update system date, system time, supervisor password, or user password.
To clear CMOS using system board jumpers
1. Shut down the computer and disconnect the power cord from it power source.
2. Move the CLR_CMOS jumper from pins 1 and 2 and place it on pins 2 and 3.
3. Wait 30 seconds before returning the jumper to its normal position.
4. Reconnect the power cord to the power source and restart the computer.
