 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."
