35.12.1.9 Offset 14h: MMBAR – Expansion Bus Base Address Register
The MMBAR is a PCI BAR in memory space that allows access to the devices on the
external Local Expansion bus. Expansion device 0 occupies the first 16MB/32MB of the
region, device 1 occupies the next 16MB/32MB, etc. Refer to Section 42.0, “Local
Expansion Bus Controller” for a description of the local expansion bus.
