2.3 Recovering the Configuration Settings
Recovering the configuration settings established in the Computer Setup (F10) Utility requires
that you first back up the settings before a recovery is needed.
The CMOS Save/Load utility firmware can be found at
& Driver Downloads for your specific model. Download the firmw are files into a folder on a
removable storage device. It is recommended that you sa ve an y modif ied computer conf iguration
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.
2.3.1 Backing up the CMOS
1. Make sure the computer to be backed up is turned on. Connect the removable storage to the
computer.
2. Boot to DOS.
http://www.hp.com under the Software
3. Type N:\folder\BIOS.exe SAVE:ABC001 (where N is the drive letter of the removable
storage) to save the CMOS setting to the removable storage device.

3.1 Initial Configuration and Deployment
HP computers come with a preinstalled system software image. After a brief software
“unbundling” process, the computer is ready to be used.
A customized software image may be deployed by installing additional software applications
after unbundling the preinstalled software image.
The best deployment method depends on your information technology environment and
processes. The PC Deployment section of the Solutions and Services Web site

3.2 ROM Flash
The computer’s BIOS is stored in a programmable flash ROM (read only memory). By
establishing a supervisor password in the Computer Setup (F10) utility , you can protect the ROM
from being unintentionally updated or overwritten. This is important to ensure the operating
integrity of the computer. Should you need or wan t to up grade th e BIOS, yo u may download the
latest BIOS images from the HP driver and support page: http://www.hp.com/support.
CAUTION: For maximum ROM protection, be sure to establish a supervisor password. The supervisor
Ä
password prevents unauthorized ROM upgrades.
3.2.1 FailSafe Boot Block ROM
The FailSafe Boot Block ROM allows for system recovery in the unlikely event of a ROM flash
failure, for example, if a power failure were to occur during a ROM upgrade. The Boot Block is a
flash-protected section of the ROM that checks for a valid system ROM flash when power to the
system is turned on.
■ If the system ROM is valid, the system starts normally.
■ If the system ROM fails the validation check, the FailSafe Boot Block ROM provides
enough support to start the system from a bootable removable media that automatically
invokes system BIOS upgrade utilities.
To recover the system after it enters Boot Block recovery mode, complete the following steps:
Service Reference Guide, dx2100 MT 404569-001 3–1
Desktop Management
1. Remove all removable media and turn off the power.
2. Insert a diskette containing the desired BIOS image file in the root directory . The media must
be formatted using the FAT32 file system.
3. Turn on power to the system.
The failsafe Boot Block BIOS will attempt to start the system from a bootable device. If no
bootable device is found, an error message will appear.
4. Remove the removable media used to upgrade the BIOS.
5. Turn the power on to restart the computer.
3.2.2 Dual-State Power Button
With Advanced Configuration and Power Interface (ACPI) enabled for Windows XP, the power
button can function either as an on/off switch or as a suspend button. The suspend feature does
not completely turn off power, but instead causes the computer to enter a low-power standby.
This allows you to quickly power down without closing applications and to quickly return to the
same operational state without any data loss.
To change the power button’s configuration, complete the following steps:
1. Left click on the Start Button, then select Control Panel > Performance and
Maintenance > Power Options.
2. In the Power Options Properties, select the Advanced tab.
3. In the Power Button section, select the desired power button setting.
After configuring the power button to function as a suspend b utton, press the power button to put
the system in a very low power state (suspend). Press the button again to quickly bring the system
out of suspend to full power status. To completely turn of f all po wer to the system, press and hold
the power button for four seconds.
CAUTION: Do not use the power button to turn off the computer unless the system is not responding;
Ä
turning off the power without operating system interaction could cause damage to or loss of data on the
hard drive.
3.2.3 Power Management
Power Management is a feature that saves energy by shutting down certain components of the
computer when they are not in use, thus saving energy without having to shut down the computer.
With Advanced Configuration and Power Interface (ACPI) enabled for Windows XP, timeouts
(the period of inactivity allowed before shutting down these components) can be enabled,
customized, or disabled using the operating system.
1. In Windows XP, left click on the Start Button, then select Control Panel > P o wer Options.
2. In the Power Options Properties, select the Power Schemes tab.
3. Select the desired power scheme settings.
Use Display Properties to establish, modify, or disable Power Management settings for the
monitor. To access Display Properties, right click on the Windows Desktop, then choose
Properties.

3.2.4 World Wide Web Site
When making the transition to new or revised operating systems, it is important to implement the
support software designed for that operating system. If you plan to run a version of Microsoft
Windows that is different from the version included with your computer, you must install
corresponding device drivers and utilities to ensure that all features are supported and
functioning properly.
HP has made the task of locating, accessing, evaluating, and installing the latest support software
easier. You can download the software from
the latest device drivers, utilities, and flashable ROM images needed to run the latest Microsoft
Windows operating system on your HP computer.
3.3 Security
3.3.1 Password Security
The user password prevents unauthorized use of the computer by requiring entry of a password to
access applications or data each time the computer is turned on or restarted. The supervisor
password specifically prevents unauthorized access to Computer Setup, and can also be used as
an override to the user password. That is, when prompted for the user password, entering the
supervisor password instead will allow access to the computer.
Desktop Management
