Table 3-4Computer Setup—Security (continued)

DriveLock Security

Allows you to assign or modify a master or user password for hard drives. When this feature is

 

enabled, the user is prompted to provide one of the DriveLock passwords during POST. If neither

 

is successfully entered, the hard drive will remain inaccessible until one of the passwords is

 

successfully provided during a subsequent cold-boot sequence.

 

NOTE: This selection will only appear when at least one drive that supports the DriveLock

 

feature is attached to the system.

 

 

Secure Boot

This is a feature of Windows 8.

Configuration

● Legacy Support—Enable/Disable. Allows you to turn off all legacy support on the computer,

 

 

including booting to DOS, running legacy graphics cards, booting to legacy devices, and so

 

on. If set to disable, legacy boot options in Storage > Boot Order are not displayed. Default

 

is enabled.

 

● Secure Boot—Enable/Disable. Allows you to make sure an operating system is legitimate

 

before booting to it, making Windows resistant to malicious modification from preboot to full

 

OS booting, preventing firmware attacks. UEFI and Windows Secure Boot only allow code

 

signed by pre-approved digital certificates to run during the firmware and OS boot process.

 

Default is disabled, except for Windows 8 systems which have this setting enabled. Secure

 

Boot enabled also sets Legacy Support to disabled.

 

● Key Management—This option lets you manage the custom key settings.

 

◦

Clear Secure Boot Keys—Don't Clear/Clear. Allows you to delete any previously loaded

 

 

custom boot keys. Default is Don't Clear.

 

◦

Key Ownership—HP Keys/Custom Keys. Selecting Custom Mode allows you to modify

 

 

the contents of the secure boot signature databases and the platform key (PK) that

verifies kernels during system start up, allowing you to use alternative operating systems. Selecting HP Keys causes the computer boot using the preloaded HP-specific boot keys. Default is HP Keys.

● Fast Boot—Enable/Disable. Fast boot disables the ability to interrupt boot, such as pressing f keys to access items before the operating system loads. Default is disabled.

NOTE: If Windows 8 detects a serious error, it will interrupt the boot process automatically and display advanced boot options.

From Windows 8, you can press Shift and select Restart to access the screen that lets you boot to a device or troubleshoot your computer.
