1 Install the Operating System
CAUTION: Do not add optional hardware or third-party devices to your computer until the
operating system is successfully installed. Doing so may cause errors and may prevent the
operating system from installing properly. Once the automatic installation has begun, DO NOT
TURN OFF THE COMPUTER UNTIL THE PROCESS IS COMPLETE. Turning off the computer
during the installation process might damage the software that runs the computer or prevent its
proper installation.
NOTE: Be sure there is a 10.2-cm (4-inch) clearance at the back of the unit and above the
monitor to permit the required airflow.
The first time the computer is turned on, the operating system is automatically installed. This takes
approximately 10 minutes, depending on the operating system being installed. Carefully read and follow
the instructions that appear on the screen to complete the installation.
NOTE: If the computer shipped with more than one operating system language on the hard
drive, the installation process could take up to 60 minutes.
If the computer was not shipped with a Microsoft operating system, some portions of this documentation
do not apply. For complete operating system installation and configuring instructions, refer to the
operating system documentation. Additional information is available in online help.
Microsoft security updates are available on the Microsoft Web site.
Installing or Upgrading Device Drivers
When installing optional hardware devices after the operating system installation is complete, you must
also install the drivers for each of the devices.
If prompted for the i386 directory, replace the path specification with C:\i386, or use the Browse button
in the dialog box to locate the i386 folder. This action points the operating system to the appropriate
drivers.
Obtain the latest support software, including support software for the operating system from
http://www.hp.com/support. Select your country and language, select Download drivers and
software, enter the model number of the computer, and press Enter.
Transferring Files and Settings
Use the Microsoft Windows XP Professional/Home Files and Settings Transfer Wizard to move files and
settings from the old computer to the new one. Click Start > All Programs > Accessories > System
ENWW Installing or Upgrading Device Drivers 1

Tools > Files and Settings Transfer Wizard. Follow the wizard's instructions to transfer files and
settings to the new computer.
HP Backup and Recovery Manager
The HP Backup and Recovery Manager is an easy-to-use, versatile application that is pre-loaded on
each system and allows you to:
●create Recovery Points to back up the entire system incrementally
●back up the entire system in a single hard archive
●back up individual files
Backups can be scheduled to occur automatically at designated intervals, or they can be initiated
manually. Recovery can be performed from the Recovery Partition on the hard drive or the Recovery
Disc Set. The Recovery Disc Set includes the Restore Plus! CD, the Microsoft Operating System, and
any Supplemental Software CDs.
NOTE: HP highly recommends that you create a Recovery Disc Set immediately before using
the computer and schedule regular automatic Recovery Point backups.
To create the Recovery Disc Set:
1. Click Start > HP Backup and Recovery > HP Backup and Recovery Manager to open the
Backup and Recovery Wizard, then click Next.
2. Select Create factory software recovery CDs or DVDs to recover the system.
3. Follow the instructions in the wizard.
The HP Backup and Recovery Manager provides two basic recovery methods. The first, recovery of
files and folders, operates in Windows. The second, PC Recovery, requires a reboot to the Recovery
Partition or from the Recovery Disc Set. To reboot to the Recovery Partition, press F11 at startup when
you see the message “Press F11 for Emergency Recovery.”
NOTE: For more information on using HP Backup and Recovery Manager, refer to the HP
Backup and Recovery Manager User Guide by selecting Start > HP Backup and Recovery >
HP Backup and Recovery Manager Manual.
You can order a Recovery Disc Set from HP by calling the HP support center. Go to the following
Web site, select your region, and click the Technical support after you buy link under the Call
HP heading to obtain the support center telephone number for your region.

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 can be found at http://www.hp.com under the Software & Driver Downloads
for your specific model. Download the firmware files into a folder on a removable storage device. It is
recommended that you save any modified 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 the
computer.
2. Boot to DOS.
3. Type N:\folder\BIOS.exe SAVE:ABC001.DAT (where Nis 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 storage to the target computer.
2. Boot to DOS.
3. Type N:\folder\BIOS.exe LOAD:ABC001.DAT (where Nis the drive letter of the removable
storage) to load the custom CMOS setting onto the target system.
