High Performance Event Timer: Select Enabled to activate the high-
performance event timer to produce periodic interrupts at a much
higher frequency than a real-time clock does when synchronizing
multimedia streams, providing smooth playback and reducing the
dependency on other timestamp calculation devices, such as an x86
RDTSC Instruction embedded in the CPU. The high-performance event
timer is used to replace the 8254 programmable interval timer.
ACPI APIC Support: Select Enabled to include the ACPI APIC Table
Pointer in the RSDT pointer list.
Note: Only available when ACPI is enabled on an ACPI-aware
operating system.
APIC ACPI SCI IRQ: When this item is set to Enabled, APIC ACPI SCI IRQ
is supported by the system.
Headless Mode: Enables the system to function without a keyboard,
monitor, or mouse attached.
Note: Only available when ACPI is enabled on an ACPI-aware
operating system.

v3.0. Please refer to ACPI's website for further explanation: http://
