Figure 1-3. Main Memory Address Range
Main Memory Address Range (1 MB to TOLUD)
This address range extends from 1 MB to the top of physical memory that is permitted
to be accessible by the IMC (as programmed in the TOLUD register). All accesses to
addresses within this range will be forwarded by the IMC to the DRAM unless they fall
into the optional TSEG, optional ISA Hole, or optional IGD stolen VGA memory.
The processor provides a maximum DRAM address decode space of 4 GB. The
processor does not remap APIC memory space. This means that as the amount of
physical memory populated in the system reaches 4 GB, there will be physical memory
that exists yet is non-addressable and therefore unusable by the system.
The processor does not limit DRAM address space in hardware.
ISA Hole (15 MB–16 MB)
A hole can be created at 15 MB–16 MB as controlled by the fixed hole enable in Device
0 space. Accesses within this hole are forwarded to the DMI. The range of physical
DRAM memory disabled by opening the hole is not remapped to the top of the memory
– that physical DRAM space is not accessible. This 15-MB to 16-MB hole is an optionally
enabled ISA hole.
