System Resource Alert
This feature is available when used with Supero Doctor III in the Windows OS en-
vironment. SDIII is used to notify the user of certain system events. For example,
if the system is running low on virtual memory and there is insuffi cient hard drive
space for saving the data, you can be alerted of the potential problem.
Auto-Switching Voltage Regulator for the CPU Core
The auto-switching voltage regulator for the CPU core can support up to 20A cur-
rent and auto-sense voltage IDs ranging from 0.83V to 1.63V. This will allow the
regulator to run cooler and thus make the system more stable.
Thermal Management 2 (TM2)
When TM2 is enabled in the BIOS and the CPU temperature reaches a pre-defi ned
threshold, a thermal monitoring mechanism will reduce the process speed by lower-
ing the bus-to-core ratio of the processor core clock and will decrease the voltage
input by changing the CPU VID. This combination of reduced CPU bus frequency
and CPU VID effectively decreases CPU power consumption to prevent processor
overheat and greatly increases system stability. (*This function is available for the
CPUs that support TM2.)
1-5 ACPI Features
ACPI stands for Advanced Confi guration and Power Interface. The ACPI specifi -
cation defi nes a fl exible 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 operating
system-independent interface for confi guration control. ACPI leverages the Plug
and Play BIOS data structures while providing a processor architecture-indepen-
dent implementation that is compatible with the Windows 2000, Windows 2003 and
Windows XP Operating Systems.
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start blinking
to indicate that the CPU is in suspend mode. When the user presses any key, the
CPU will wake-up and the LED will automatically stop blinking and remain on.
