These 8 bits select the base address for this 16MB memory space used by this graphics
controller for the memory mapped registers and linear accesses to the frame buffer.
These 20 bits always return 0 to indicate that the size of this memory space is 16MB.
This bit always returns a value of 0 when read, indicating that the data in this 16MB memory
space should not be prefetched by the CPU.
These 2 bits always return values of 0 when read, indicating that this 16MB memory space
may be placed anywhere in the system’s 32-bit address space by the system’s PCI
configuration software.
This bit always returns a value of 0 when read, indicating that this is a memory space, not
an I/O space.
