When [Auto] is selected, the BIOS detects the PCI devices installed on the host PCI bus bridge. The BIOS automatically sets the optimal I/O resource size. When the sum of specified I/O resource size is smaller than the I/O resource size of the system (64 KB), a surplus I/O resource size is used for the host PCI bus bridge with the largest number. The sum of the specified I/O resource size must be smaller than 64kB or must be 64kB. If the size is larger than 64kB, the system detects a setting error at the next start up and the I/O resource size settings are initialized. (The procedure is the same as selecting option [Auto].)
