Audio Function (Optional)
The board comes with a 3-D audio controller and an audio I/O daughterboard connector.
The audio I/O daughterboard integrates the following ports:
•
Mono microphone port
•
Stereo line-in port
•
Stereo line-out port
•
Game/MIDI port
These connectors enable the system to accommodate external audio devices. For instructions
on how to connect the external audio devices, refer to section 1.3.6. Connecting Multimedia
Components.
2.7
USB
USB (Universal Serial Bus) is a new serial bus design that is capable of cascading
low-/medium-speed peripherals (less than 12 Mbps) such as a keyboard, mouse, joystick,
scanner, printer and modem/ISDN. With USB, complex cable connections at the back panel
of your PC can be eliminated.
The board comes with two USB ports (CN8, CN9) and one USB connector (CN6). See
Figure 2-1 or Figure 2-2 for the location of the ports.
2.8
Hardware Monitoring Function
The onboard Hardware Monitoring controller is capable of checking the system health status,
either locally or in a computer network, by using software such as Intel LDCM (LAN Desk
Client Manager). It monitors the system voltage, CPU temperature, and CPU fan. If any of
these system parameters exceed the pre-defined range, an SMI (System Management
Interrupt) will let BIOS generate an alert message and send this message to the Management
software, either locally or remotely. This early-stage system failure detection can prevent
system from abnormal shutdown.
