    No, PCI is little endian. AD[1:0] addresses BE0#, the low order byte,
    when addressing devices in I/O address space.

    Memory mode devices do not interpret A[1:0] as address bits and instead
    must use the BE# signals. Same for configuration space.

    However, for all the things we do nowadays, PCI is pretty much endian
    neutral in the domain of memory space.
