ACPI 2.0 Support

Common Options : Enabled, Disabled

Quick Review

While its name hints that this BIOS feature is a toggle to enable ACPI 2.0 features, this is not the case. Enabling this BIOS feature does not turn on ACPI 2.0. Similarly, disabling it does not turn on the original ACPI 1.0 standard. It disables ACPI completely.

This BIOS feature merely determines if ACPI support is enabled on the motherboard chipset level. The name ACPI 2.0 Support merely means that this motherboard supports the ACPI 2.0 standard.

If enabled, ACPI support will be enabled on the motherboard chipset level. If the operating system supports ACPI, it can then use ACPI to configure the hardware, as well as control the system's power management features.

If disabled, ACPI support will be disabled on the motherboard chipset level. Even if the operating system supports ACPI, it cannot use ACPI to configure the hardware or control its power management features.

It is recommended that you enable this BIOS feature. This allows an ACPI-compliant operating system to fully control the configuration of hardware devices and their power management.

Please note that for Microsoft Windows to run in ACPI mode, it needs to be installed with ACPI enabled in the BIOS. If you switch from ACPI to non-ACPI mode, or vice versa, Microsoft Windows will fail to boot. You need to reinstall Microsoft Windows everytime you switch modes.
