CPU THRM-Throttling
When the system enters Doze mode, the CPU clock runs only part of the
time. You may select the percent of time that the clock runs.
Wake up by PCI Card
By default, this field is Disabled.
Power On by Ring
This field enables or disables the power on of the system through the
modem connected to the serial port or LAN.
Resume by Alarm
This field enables or disables the resumption of the system operation.
When enabled, the user is allowed to set the Date and Time.
Reload Global Timer Events
The HDD, FDD, COM, LPT Ports, and PCI PIRQ are I/O events that can
prevent the system from entering a power saving mode or can awaken
the system from such a mode. When an I/O device wants to gain the
attention of the operating system, it signals this by causing an IRQ to
occur. When the operating system is ready to respond to the request, it
interrupts itself and performs the service.
HPET Support
HPET stands for High Precision Event Timer. HPET can produce
periodic interrupts at a much higher resolution than the RTC and is used
to synchronize multimedia streams, providing smooth playback and
reducing the need to use other timestamp calculations such as an
instruction. HPET is not supported in Windows XP,
Windows Server 2003, or earlier Windows versions. HPET is supported
under Linux and Windows Vista. By default, this field is enabled.
HPET Mode
By default, this field is set to 32-bit mode.
