System Address Map

Datasheet

213

⎯ Addresses decoded to the Memory Mapped Range of the Internal Graphics Device

(MMADR range). There is a MMADR range for device 2 function 0 and a MMADR

range for device 2 function 1. Both ranges are forwarded to the Internal Graphics

Device.

The exceptions listed above for internal graphics and the PCI Express ports MUST NOT overlap

with APCI Configuration, FSB Interrupt Space and High BIOS Address Range.
