ACPI STR
The system board is designed to meet the ACPI (Advanced Con-
figuration and Power Interface) specification. ACPI has energy sav-
ing features that enables PCs to implement Power Management
and Plug-and-Play with operating systems that support OS Direct
Power Management. Currently, only Windows

out having to go through the sometimes tiresome process of
closing files, applications and operating system. This is because the
system is capable of storing all programs and data files during the
entire operating session into RAM (Random Access Memor y)
when it powers-off. The operating session will resume exactly
where you left off the next time you power-on the system. Refer
to “Using the Suspend to RAM Function” in appendix A for more
information.
