	You do not have SoundStorm technology on your motherboard. NF7-S uses
MCP-T, while NF7 and NF7-M (with integrated video) uses MCP, which, in
oppose to MCP-T have no interface to second network card (based on 3COM's
chip), have no IEEE-1394A (aka Firewire) and have no SoundStorm
Technology. Realtek's ALC650, that is used on that motherboards is capable
to switch to 6 channel mode in Windows driver... Have no any idea how to
do that in FreeBSD.
