Case 2 – Greater than 4 GB of Physical Memory
In this case the amount of memory remapped is the range between TOLUD and 4 GB.
This physical memory will be mapped to the logical address range defined between the
REMAPBASE and the REMAPLIMIT registers.
This physical memory will be mapped to the logical address range defined between the
REMAPBASE and the REMAPLIMIT registers.
Example: 5 GB of Physical Memory, with 1 GB allocated to Memory Mapped IO:
• Populated Physical Memory = 5 GB
• Address Space allocated to memory mapped IO (including Flash, APIC, and Intel
• Address Space allocated to memory mapped IO (including Flash, APIC, and Intel
TXT) = 1 GB
• Remapped Physical Memory = 1 GB
• TOM – 01_4000_0000h (5 GB)
• ME stolen size – 00000b (0 MB)
• TOUUD – 01_8000_0000h (6 GB) (1 MB aligned)
• TOLUD – 00_C000_000h (3 GB)
• REMAPBASE – 01_4000_0000h (5 GB)
• REMAPLIMIT – 01_7FF0_0000h (6 GB-1)
• TOM – 01_4000_0000h (5 GB)
• ME stolen size – 00000b (0 MB)
• TOUUD – 01_8000_0000h (6 GB) (1 MB aligned)
