When [Auto] is selected, the BIOS detects the PCI devices installed on the host PCI bus bridge. The BIOS automatically sets the optimal PCI Gap size. When the specified PCI Gap size is smaller than the required PCI Gap size for the installed device, the BIOS neglects the specified PCI Gap size and sets the optimal PCI Gap size. When the sum of the specified PCI Gap size is smaller than the total PCI Gap size of the system, a surplus PCI Gap size is used for the host PCI bus bridge with the largest number.
