ACPI STR
The mainboard is designed to meet the ACPI (Advanced Configura-
tion and Power Interface) specification. ACPI has energy saving fea-
tures that enables PCs to implement Power Management and Plug-
and-Play with operating systems that support OS Direct Power
Management. Currently, only Windows
®
98/2000/ME/XP supports
the ACPI function. ACPI when enabled in the Power Management
Setup will allow you to use the Suspend to RAM function.
With the Suspend to RAM function enabled, you can power-off the
system at once by pressing the power button or selecting “Standby”
when you shut down Windows
®
98/2000/ME/XP without 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 Memory) 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.
Important:
The 5VSB power source of your power supply must support
1A.
AC Power Failure Recovery
When power returns after an AC power failure, you may choose to
either power-on the system manually, let the system power-on
automatically or return to the state where you left off before power
failure occurs. Refer to “PWR Lost Resume State” in the Power
Management Setup section in chapter 3 for more information.
Virus Protection
Most viruses today destroy data stored in hard drives. The
mainboard is designed to protect the boot sector and partition
table of your hard disk drive.
