Processor x2APIC Support

Use this option to enable or disable x2APIC support. When enabled, processor x2APIC support helps operating systems run more efficiently on high core count configurations and optimizes interrupt distribution in virtualized environments. Enabled mode does not enable x2APIC hardware, but provides the support necessary to the operating system. Unless you are using an older hypervisor or operating system that is not compatible with x2APIC support, leave this option enabled.
