Want a way to boot up your Windows Vista PC from a full shut down in a matter of seconds? The solution is: ASRock “Instant Boot” that leverages the S3 and S4 ACPI (Advanced Configuration and Power Interface) features which normally enable the Sleep/Standby and Hibernation modes in Windows to cut boot times down to something like 4 seconds. By calling S3 and S4 at specific times during the startup and shutdown process, Instant Boot enables you to boot up to your Windows Vista or XP desktop in a few seconds seconds, even after a total shut down.

There are two modes of Instant Boot available:

• Fast mode - This uses S3 and boots up in around four seconds
• Regular Mode - This uses S4 and takes some 20 to boot
