HP Pro 4300 manual DriveLock Security, Secure Boot, Configuration

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.
