ACPI Function (Enabled)
This mainboard supports ACPI (Advanced Configuration and Power man-
agement Interface). Use this item to enable or disable the ACPI feature.
Note:
ACPI is a power management specification that makes hardware status in-
formation available to the operating system. ACPI enables a PC to turn its
peripherals on and off for improved power management. It also allows the
PC to be turned on and off by external devices, so that mouse or keyboard
activity wakes up the computer.
ACPI Suspend Type (S1 (POS))
Use this item to define how your system suspends. In the default, S1(POS),

the exception of a refresh current to the system memory.
