Power Management

Wake on LAN	This option allows the computer to power up from the off state
	when triggered by a special LAN signal. Wake-up from the
	Standby state is unaffected by this setting and must be
	enabled in the operating system. This feature only works when
	the computer is connected to AC power supply.
	• Disabled — Does not allow the system to power on by
	special LAN signals when it receives a wake-up signal
	from the LAN or wireless LAN.
	• LAN Only — Allows the system to be powered on by
	special LAN signals.
	This option is Disabled by default.
POST Behavior

Numlock LED	Allows you to enable or disable the Numlock feature when
	your computer starts. This option is enabled by default.
Keyboard Errors	Allows you to enable or disable the keyboard error reporting
	when the computer starts. This option is enabled by default.
POST Hotkeys	Allows you to specify the function keys to display on the
	screen when the computer starts.
	Enable F12 — Boot menu (enabled by default)
Fast Boot	This option can speed up the boot process by bypassing some
	compatibility steps:
	• Minimal — The system boots quickly, unless the BIOS
	has been updated, memory changed, or the previous
	POST did not complete.
	• Thorough — The system does not skip any steps in the
	boot process.
	• Auto — This allows the operating system to control
	this setting (this works only when the operating system
	supports Simple Boot Flag).
	This option is set to Thorough by default.
Virtualization Support

Virtualization	This option specifies whether a Virtual Machine Monitor
	(VMM) can utilize the additional hardware capabilities
