ACPI (Advanced
Configuration and Power
Management Interface)
Allows the system to enter and wake from low power modes (sleep states).
Enables an operating system to control system power consumption based on the dynamic workload.
Makes it possible to place individual cards and peripherals in a low-power or powered-off state without
affecting other elements of the system.
Supports ACPI 4.0 for full compatibility with 64-Bit operating systems.
Ownership Tag
A user-defined string stored in non-volatile memory that is displayed in the BIOS splash screen.
Remote Wakeup/Remote
Shutdown
System administrators can power on, restart, and power off a client computer from a remote location.
Instantly Available PC
(Suspend to RAM - ACPI
sleep state S3)
Allows for very low power consumption with quick resume time.
Remote System
Installation via F12 (PXE
2.1) (Remote Boot from
Server)
Allows a new or existing system to boot over the network and download software, including the
operating system.
ROM revision levels
Reports the system BIOS revision level in Computer Configuration Utility (F10 Setup). Version is
available through an industry standard interface (SMBIOS) so that management SW applications can
use and report this information.
System board revision
level
Allows management SW to read the revision level of the system board
Revision level is digitally encoded into the HW and cannot be modified.
Start-up Diagnostics
(Power-on Self-Test)
Assesses system health at boot time with selectable levels of testing.
Auto Setup when new
hardware installed
System automatically detects addition of new hardware.
Keyboard-less Operation
The system can be booted without a keyboard.
Localized ROM Setup
Common BIOS image supports System Configuration Utility (F10 Setup) menus in 12 languages with
local keyboard mappings.
Asset Tag
Allows the user or MIS to set a unique tag string in non-volatile memory.
Per-slot Control
Allows I/O slot parameters (option ROM enable/disable, bus latency) to be configured individually.
Adaptive Cooling
Fan control parameters are set according to detected hardware configuration for optimal acoustics.
Pre-boot Diagnostics
Early (pre-video) critical errors are reported via beeps and blinks on the power LED.
