The Asus A8N SLI has two LAN ports. Port one is controlled by the Nvidia chip and port two is controlled by a Marvell chip. If I am going to use only one port, does it matter which one? Is one preferable to the other? Should I disable the unused one in the BIOS? Also which drivers are used for these ports? The driver CD has a "Marvell Yukon Gigabit Ethernet Driver." Is this driver for port two only or for both ports. If it is for port two only, where is the driver for the Nvidia port?
