Restoring Novell SLED on page 28 Restore methods The Windows 7 or Windows Business Vista operating system can be reinstalled using the HP RestorePlus! process. The Windows XP Professional operating system can be reinstalled using the RestorePlus! process or the HP Backup and Recovery Manager.
Page 37: Ordering Backup Software

Ordering backup software If you cannot create system recovery CDs or DVDs, you can order a recovery disk set from the HP support center. To obtain the support center telephone number for your region see http://www.hp.com/support/contactHP. Restoring Windows 7 or Windows Vista This section describes how to restore Windows 7 or Windows Vista.
Page 38: Restoring Windows Xp Professional

Depending on the options, there might be additional DVDs you can create. Follow the prompts to create RestorePlus!, operating system, and HPBR media. If you are unable to create CD/DVDs on your workstation, call HP Support and request a RestorePlus! media kit. For worldwide technical support phone numbers, see http://www.hp.com/support.
Page 39: Creating Hp Backup And Recovery (hpbr) Media

The Initial Recovery Point was captured when the RestorePlus! media set was created previously. If the IRP was not created, start the HP Backup and Recovery Manager and create recovery points using the Expert mode. Follow the HPBR online documentation for instructions.
Page 40: Restoring The Operating System

Restoring the operating system CAUTION: Before you restore the operating system, back up your data. When you run RestorePlus! from media, the process deletes all information on the primary hard drive, including all partitions. If you run RestorePlus! from the recovery partition, only the root (C:) partition is affected.
Page 41: Creating Restore Media

Creating restore media THE SUSE Linux Enterprise Desktop preload includes a SUSE ISO icon on the desktop. You can click this icon to go to the /iso directory.

Page 65: Sata Hard Disk Drive Security

To balance this level of security with the need to address the issue of a forgotten password, the HP implementation of DriveLock employs a two-password security scheme. One password is intended to be set and used by a system administrator, while the other is typically set and used by the user.
Page 66: Drivelock Applications

For users with less stringent security requirements, HP does not recommend enabling DriveLock. Users in this category include personal users, or users who do not maintain sensitive data on their hard disk drives as a common practice.
Page 67

Enabling DriveLock To enable and set the DriveLock user password: Power on or restart the workstation.
