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 is necessary. For more information about

HP Insight Diagnostics

The HP Insight Diagnostics utility allows you to view information about th e hardware configu­ration of the computer and perform hardware diagnostic tests on the subsystems of the com­puter. The utility simplifies the process of effectively identifying, diagnosing, and isol ating
hardware issues.

Insight Diagnostics may be downloaded from the HP Web site using the following procedure:

1. Go to www.hp.com

2. Click the Software & Download driver link.

3. Enter the product number (for example, dc7510) in the text box and press the Enter key.

4. Select the specific product.

5. Select the OS.

6. Click the Diagnostics link.

7. Select HP Insight Diagnostics Offline Edition.

8. Click Download.

NOTE: The download includes instructions on how to create a bootable CD.

Clearing CMOS

1. Remove the chassis access panel.

2. Locate the CMOS jumper.

3. Remove the blue CMOS jumper from pins 4 and 6 and put the jumper on pins 2 and 4. Th is
clears CMOS.

4. Put the jumper back on pins 4 and 6.

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

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

Recovering the Configuration Settings

Recovering the configuration settings established in the Computer Setup (F1 0) Utility requires
that you first back up the settings before a recovery is needed.
The CMOS Save/Load utility can be found at http://www.hp.com
Downloads for your specific model. Download the firmware files into a folder on a removable
storage device. It is recommended that you save any modifi ed computer configuration settings
to a diskette, a USB flash media device, or a diskette-like device (a storage device set to emulate
a diskette drive) and save the diskette or device for possible future use.

Backing Up the CMOS

1. Make sure the computer to be backed up is turned on. Connect the removable storage to the­computer.

2. Boot to DOS.

3. Type N:\folder\BIOS.exe SAVE:ABC001.DAT (where N is the drive letter of the removable
storage) to save the CMOS setting to the removable storage device.

Restoring the CMOS

1. Make sure the target computer is turned on. Connect the removable s tor age to the t ar get c om­puter.

2. Boot to DOS.

3. Type N:\folder\BIOS.exe LOAD:ABC001.DAT (where N is the drive letter of the removable
storage) to load the custom CMOS setting onto the target system.
