Processor Configuration Registers  
2.3.2  
Main Memory Address Range (1 MB – TOLUD)  
This address range extends from 1 MB to the top of Low Usable physical memory that is  
permitted to be accessible by the processor (as programmed in the TOLUD register).  
The processor will route all addresses within this range to the DRAM unless it falls into  
the optional TSEG, optional ISA Hole, or optional IGD stolen VGA memory.

2.3.2.1  
ISA Hole (15 MB – 16 MB)  
The ISA Hole is enabled in the Legacy Access Control Register in Device 0 configuration  
space. If no hole is created, the processor will route the request to DRAM. If a hole is  
created, the processor will route the request to DMI, since the request does not target  
DRAM.  
Graphics translated requests to the range will always route to DRAM.
