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, and vice versa.
Select Workstation if your system is used as a Workstation. Select Server if your
system is used as a Server. Select Disabled to disable the fan speed control func-
tion and allow the onboard fans to constantly run at full speed. The Options are:
Full Speed, Server, Workstation/Desktop, and Super Quiet.
Voltage Readings
The following voltage readings will be displayed.
Vcore1, Vcore2, 1.5V, 5VDD, 5VSB, 12V, -12V, 3.3Vcc, 3.3VSB, VBAT and Vtt.
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.

S3 or S4 State. The options are Enabled and Disabled.
PS2 KB/MS Wake Up
Select Enable to "wake-up" the system using either the PS2 keyboard or mouse (if
equipped) when the system is in S3 (Sleep) or S4 (Hibernate) state. The options
are Enabled and Disabled.
