You can insert up to 2 PCI audio or video cards.
If you want to insert one audio card, use the bottom PCI
card. This will act as AudioEncoder-2. Again, AudioEncoder-1
is the on-boards audio card.
If you want to insert 2 audio cards, use both bottom and top
PCI slots. With this setup you will have 3 audio cards:
AudioEncoder-1 (on board)
If you want to insert a video card, always use the top PCI slot. Any combination of
audio cards is valid, as long as you use the video card on the TOP PCI slot.
