Datasheet
In an internal graphics configuration, there are three exceptions to this rule:
The exceptions listed above for internal graphics and the PCI Express ports MUST NOT
overlap with APCI Configuration Space, FSB Interrupt Space and High BIOS
Address Range.
PCI Memory Address Range
1. Addresses decoded to the Graphics Memory Range. (GMADR range)
2. Addresses decoded to the Graphics Translation Table range (GTTADR range).
3. 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.
