NOTE
The given bus numbers only apply if all PCI Express Ports are enabled in the BIOS
setup. If for example PCI Express Port 2 is disabled then PCI Express Port 3 will be
assigned bus number 3 instead of bus number 4, Port 4 will be assigned bus number 4
and the standard PCI slots will be assigned bus number 6. Furthermore, the
respective PCI Express Root Port is hidden if the corresponding PCI Express Port is
disabled.
