Soft-Off by PWRBTN
This field defines the power-off mode when using an ATX power
supply. The Instant Off mode allows powering off immediately upon
pressing the power button. In the By Hardware mode, the system powers
off when the power button is pressed for more than four seconds or
enters the suspend mode when pressed for less than 4 seconds.
HPET Support
HPET, or High Precision Event Timer (formerly known as Multimedia
Timer) is a hardware timer that is supported under Linux and Windows
Vista. It can produce periodic interrupts at a much higher resolution than
the RTC and is often used to synchronize multimedia streams, providing
smooth playback and reducing the need to use other timestamp
calculations such as an x86 CPU’s RDTSC instruction.
