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.
