 ACPI APIC Support [Enabled]
The ACPI APIC Support BIOS option adds 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. It provides the physical address
of the RSDT. The RSDT itself is identified in memory because it starts with the signature
"RSDT."
