The Four Speakers System
Onboard Sound provides 2 wave channels (front/rear),
known as the 4 speakers system. When application
programs via DirectSound® 3D or A3D® interface locate
the sound sources to the listener's back, the two rear
speakers will work to enhance the rear audio positional
effect, so as to complement the insufficiency of using only
two front speakers to emulate the audio effect. The
following is the hardware installation and the software
setups:
1. Speaker Installation
Connect the front pair speakers to the Line-out jack on the
Sound port, and then, connect rear pair speakers to Line-in/
Rear jack. The original Line-in can be moved to Aux-in.
2. Speaker Position
Set up your speakers similar to the following figure to get
the best audio result.
3. Mixer Setup
When user was setup the PCI Audio Application, there is a
4 speakers option in the Volume Control of the Mixer. Click
on the 4 SPK icon to enable this option. This means that the
rear speakers are connected to Line-in/Rear jack. However,
in order to avoid hardware conflicts, DO NOT enable this
option when Line-in/Rear jack is connected to other external
Line-in sources. Turn on/off the output of the front speakers
and adjust the volume of speakers to the same volume for
the rear speakers.
4. Demo
Execute the "Helicopter" demo within the C3D HRTF
Positional Audio Demos of the PCI Audio Application.
When the helicopter flies behind you, it means that the rear
speakers are working properly.

BIOS Setup
This chapter explains how to configure the mainboard’s
BIOS setup. The BIOS setup is from AMI.
After you have configured the mainboard and
assembled the components, turn on the computer and
run the software setup to ensure that the system
information is correct.
The software setup of the board is achieved
through Basic Input-Output System (BIOS)
programming. You use the BIOS setup program to
tell the operating system what type of devices are
connected to your board.
The system setup is also called CMOS setup. Normally,
you need to run system setup if either the hardware is not
identical with the information contained in the CMOS
RAM, or the CMOS RAM has lost its power.
Note:Hold down the <End> key then power on to reboot the
system after updating BIOS.
