Front Audio Connector

If the housing has been designed with an audio port on the front panel, you’ll be able to connect onboard audio to front panel through this connector. By the way, please remove 5-6and9-10jumper caps from the Front Audio Connector before connecting the cable. Please do not remove these5-6and9-10yellow jumper caps if there’s no audio port on the front panel.

Battery-lessand Long Life Design

This Motherboard implements Flash ROM and a special circuit that allows you to save your current CPU and CMOS Setup configurations without using the battery. The RTC (real time clock) can also keep running as long as the power cord is plugged. If you lose your CMOS data by accident, you can just reload the CMOS configurations from Flash ROM and the system will recover as usual.

CPU Over-currentProtection

Over Current Protection has been popularly implemented on ATX 3.3V/5V/12V switching power supply for a while. However, new generation CPU is able to use regulator of different voltages to transfer 12V to CPU voltage (for example, to 2.0V). This motherboard is with switching regulator onboard that supports CPU over-currentprotection, and it applies to 3.3V/5V/12V power supply for providing full lineover-currentprotection.

Note: Although we have implemented protection circuit try to prevent any human operating mistake, there is still certain risk that CPU, memory, HDD,add-oncards installed on this motherboard may be damaged because of component failure, human operating error or unknown nature reason.AOpen cannot guaranty the protection circuit will always work perfectly.

AOConfig Utility

AOpen always dedicated to provide users a much friendlier computer environment. We now bring you a comprehensive system detective utility. AOconfig is a Windows based utility withuser-friendlyinterface that allows users to obtain information of the operation system and

hardware such as motherboard, CPU, memory, PCI devices and IDE devices. The powerful utility also displays the version of BIOS and firmware for your convenience of maintenance.

Moreover, AOconfig allows users to save information in *.BMP or *.TXT format which users may collect the system information in detail and send them to AOpen directly for technical support or further diagnosis of system problem.

1.The system page shows the detail information of the motherboard, the operating system, the processor, and BIOS version.

2.The PCI device page shows the configurations of all PCI devices installed on your motherboard.

3.This page presents the IDE devices information, such as the serial number, the manufacturer, the firmware version, and capacity.

4.From this page, users may obtain the technical support information of AOpen. Moreover, detailed information could be saved in .bmp or .txt format.

NOTE: AOconfig can be used in Windows 98SE/ME, NT4.0/2000 and Windows XP. Please be informed that AOconfig can only be operated in a system equipped with an AOpen motherboard. Meanwhile, all applications must be closed before starting AOconfig.
