Power Interface) features. By enabling this feature the system RSDP (Root System
Description Pointer) is able to obtain physical addresses for other 64-bit fixed system
description tables.

ACPI APIC Support [Enabled]
Use the ACPI APIC Support option to add a pointer to an ACPI APIC table in the RSDT
(Root System Description Table). The RSDT is an array of pointers that direct the system
to the physical addresses of other description tables. The RSDT is the main ACPI table.
The RSDP is located in low memory space of the system and provides the physical
address of the RSDT. The RSDT itself is identified in memory because it starts with the
signature "RSDT."
Disabled Pointers to the APIC APIC table are not be provided in the
RSDT
Enabled D
EFAULT
Pointers to the APIC APIC table are provided in the RSDT
