Throttle Duty Cycle
Clock Throttling means at the Doze/Standby state,
the CPU clock count in a given time (not the
frequency) is reduced to the ratio specified in this
parameter. Actually, the period per CPU clock is not
changed. For example, a 66MHz CPU clock remains
the same 30ns clock period when system goes into
Doze/Suspend. The chipset generates the STPCLK
(stop clock) signal periodically to prevent CPU for
accepting clock from clock generator. For full power
on, the CPU can receive 66M count in one second. If
the Slow Clock Ratio is set to 50%, the CPU will only
receive 33M clock count in one second. This will
effectively reduce CPU speed as well as CPU power.
VGA Active Monitor
To enable or disable the detection of VGA activity for
power down state transition.
Soft-Off by PWR-BTTN
This is a specification of ACPI and supported by
hardware. When Delay 4 sec. is selected, the soft
power switch on the front panel can be used to
control power On, Suspend and Off. If the switch is
pressed less than 4 sec during power On, the system
will go into Suspend mode. If the switch is pressed
longer than 4 sec, the system will be turned Off. The
default setting is Instant-Off, soft power switch is only
used to control On and Off, there is no need to press
4 sec, and there is no Suspend.
Wake On RTC Timer
This option lets you enable or disable the RTC Wake
Up function.
