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.

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 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 or prompt the user to unplug the unit, wait 5 seconds, reattach the power

cord, and then press the power button.

Diagnostic Functions

Diagnostic functions are provided by the Setup Utility (in system ROM) and by Insight Diag-

nostics. Insight Diagnostics provides detailed system information including:

• Processor type and speed

• Memory amount, mapping, and integrity

• Hardware peripheral availability/settings

• Hard drive type, space used/available

• System identification, asset tracking

Insight Diagnostics may be found on the Documentation and Diagnostics CD that shipped with

the computer. The tool may also be downloaded from the HP Web site using the following pro-

cedure:

1. Go to www.hp.com

2. Click the Software and Download driver link.

3. Enter the product number (for example, dc7700) 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. Select the proper language and click Download.

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

number is SP33665 or later.
