The AdvancedMC* configuration as it relates to the PCI Configuration Map can be confusing. The following additional information regarding the AMC configuration should help clarify the configuration:

•BUS 0 is the internal MCH and ICH device.

•BUS 1 is assigned to the secondary side of the PCI-to-PCI bridge 0:1e.0 (ICH bus 32bit/33MHz).

•BUS 2 to 4 is assigned to the secondary side of the PCI Express Port A of the MCH (PCI to PCI bridge 0:2.0). (Connected to PXH).

•BUS 5 is assigned to the secondary side of the PCI-to-PCI bridge 0:1c.0 (ICH bus PCI-X, no connect on MPCBL0010 SBC).

•BUS 6 to 0Eh is assigned to the secondary side of the PCI Express Port C of the MCH (PCI to PCI bridge 0:6.0). (Connected to AMC B1)

•BUS 0Fh to 17h is assigned to the secondary side of the PCI Express Port B of the MCH (PCI to PCI bridge 0:4.0). (Connected to AMC B2)

The hot plug devices (which can be added after the system has booted) will have a bus number based on the PCI BUS 0 scan order. At boot-up, Linux uses the bus number assigned by the BIOS while in POST. The PCI-Express Hot Plug driver uses the resource (BUS, IO, MEM) configured by the BIOS on the PCI Express root port.

The tree listing from Linux, with some comments, is:
