3.16 ACPI Support
The Intel
®
Workstation System supports S0, S1, S3, and S5 states. S1 is considered a sleep
state.
The wake-up sources are enabled by the ACPI operating systems with cooperation from the
drivers; the BIOS has no direct control over the wake-up sources when an ACPI operating
system is loaded. The role of the BIOS is limited to describing the wake-up sources to the
operating system.
The S5 state is equivalent to the operating system shutdown. No system context is saved when
going into S5.
3.17 Intel
®
Virtualization Technology
Intel
®
Virtualization Technology is designed to support multiple software environments sharing
same hardware resources. Each software environment may consist of an operating system and
applications. You can enable or disable the Intel
®
Virtualization Technology in the BIOS Setup.
The default behavior is disabled.
