3.2 Installing the Audio Processing Card
1. Face the bracket of the Xonar D2 audio card toward the back panel of
your computer and insert the audio card gently into an available PCI slot.
Make sure it’s completely inserted into the PCI slot. (Warning! Do not force
the audio card into the slot. Make sure that the gold pins of the card's PCI
connector are aligned with the motherboard’s PCI connector before you
insert the card into the PCI slot. If it does not fit properly, gently remove it and
try again.)
2. Secure the audio card bracket to the back of your computer with the screw
that you removed. Refer to section 3.1.
