ACPI stuff in bios A8V Deluxe

[SkeeterUK]

I currently have

ACPI 2.0 Support - disabled
ACPI APIC Support - Enabled

I was reading the bios guide section for ACPI 2.0 Support and it says it should be enabled but also warns if you switch it then windows would need to be reinstalled or something.

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.

So erm should i enable it in bios or not as i dont want to reinstall windows. Or shall i leave it?
