Figure 1-1. System Address Ranges
The rules for the above programmable ranges are:
The following figure represents system memory address map in a simplified form:
Legacy Address Range
This area is divided into the following address regions:
•
•
•
•
•
•
•
•
•
•
ALL of these ranges MUST be unique and NON-OVERLAPPING. It is the BIOS or
system designers' responsibility to limit memory population so that adequate PCI,
High BIOS, and APIC memory space can be allocated.
In the case of overlapping ranges with memory, the memory decode will be given
priority.
There are NO Hardware Interlocks to prevent problems in the case of overlapping
ranges.
Accesses to overlapped ranges may produce indeterminate results.
Peer-to-peer cycles from DMI Interface to the Internal Graphics VGA is not allowed.
