Fan Speed Control Modes
This feature allows the user to decide how the system controls the speeds of the
onboard fans. The CPU temperature and the fan speed are correlative. When the
CPU on-die temperature increases, the fan speed will also increase for effective
system cooling. Select Full Speed to allow the onboard fans to run at full speed (of
100% Pulse Width Modulation Duty Cycle) for maximum cooling. The Full Speed
setting is recommended for special system confi guration or debugging. Select
Performance for the onboard fans to run at 70% of the Initial PWM Cycle for better
system cooling. The Performance setting is recommended for high-power-consum-
ing and high-density systems. Select Balanced for the onboard fans to run at 50%
of the Initial PWM Cycle in order to balance the needs between system cooling
and power saving. The Balanced setting is recommended for regular systems with
normal hardware confi gurations. Select Energy Saving for the onboard fans to run
at 30% of the Initial PWM Cycle for best power effi ciency and maximum quietness.
The Options are: Full Speed (@100% of PWM Cycle), Performance (@70% of
PWM Cycle),
Balanced (@50% of PWM Cycle)
, and Energy Saving (@30% of
PWM Cycle).

ACPI Confi guration
Use this feature to confi gure Advanced Confi guration and Power Interface (ACPI)
power management settings for your system.
High Performance Event Timer
Select Enabled to activate the High Performance Event Timer (HPET) that produces
periodic interrupts at a much higher frequency than a Real-time Clock (RTC) does in
synchronizing multimedia streams, providing smooth playback and reducing the de-
pendency on other timestamp calculation devices, such as an x86 RDTSC Instruc-
tion embedded in the CPU. The High Performance Event Timer is used to replace
the 8254 Programmable Interval Timer. The options are
Enabled
and Disabled.
USB Device Wakeup
Select Enable to awaken the system via a USB device when the system is in S3
or S4 sleep State. The options are Enabled and
Disabled
.
PS/2 KB/MS WakeUp
This feature is used to awaken from Standby mode by a PS/2 mouse or PS/2
keyboard. The options are Enabled and
Disabled.
