Auto-Switching Voltage Regulator for the CPU Core
The auto-switching voltage regulator for the CPU core can support up to
20A of current and auto-sense voltage IDs ranging from 1.3v to 3.5v. This
will allow the regulator to run cooler and thus make the system more stable.
1-5 ACPI/PC99 Features
ACPI is an acronym meaning "Advanced Configuration and Power Inter-
face." The ACPI specification defines a flexible and abstract hardware
interface that provides a standard way to integrate power management
features throughout a PC system, including its hardware, operating system
and application software. This enables the system to automatically turn on
and off peripherals such as CD-ROMs, network cards, hard disk drives and
printers. This also includes consumer devices connected to the PC such as
VCRs, TVs, telephones and stereos.
In addition to enabling operating system-directed power management, ACPI
provides a generic system event mechanism for Plug and Play and an oper-
ating system-independent interface for configuration control. ACPI lever-
ages the Plug and Play BIOS data structures while providing a processor
architecture-independent implementation that is compatible with Windows
98, Windows NT and Windows 2000. You can check to see if ACPI has
been properly installed by looking for it in the Device Manager, which is
located in the "Control Panel" in Windows.
Microsoft OnNow
The OnNow design initiative is a comprehensive, system-wide approach to
system and device power control. "OnNow" is a term for a PC that is
always on but appears to be off and responds immediately to user or other
requests.
