Figure 1-4. PCI Memory Address Range
APIC Configuration Space (FEC0_0000h-FECF_FFFFh)
This range is reserved for APIC configuration space which includes the default I/O APIC
configuration space from FEC0_0000h to FEC7_0FFFh. The default Local (CPU) APIC
configuration space goes from FEC8_0000h to FECF_FFFFh.
CPU accesses to the Local APIC configuration space do not result in external bus
activity since the Local APIC configuration space is internal to the CPU. However, an
MTRR must be programmed to make the Local APIC range uncacheable (UC). The Local
APIC base address in each CPU should be relocated to the FEC0_0000h (4 GB-20 MB)
