ATX Stand-by Power Battery Auto Switch RTC (Real Time Clock) 00:00:00 Auto switching to ATX standby power as long as AC power line is plugged. This smart design increases battery life if you still plug battery on motherboard. Flash ROM CMOS Backup by EEPROM 60 AX4GER / AX4GER-N C P U O v er -c u r r e n t Pr o t e c ti o n Online Manual 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-current protection, and it applies to 3. 3V/5V/12V power supply for providing full line over-current protection. 5V (Protected by power supply) ATX Switching Power Supply 3. 3V (Protected by power supply) 12V (Protected by power supply) Onboard Power Regulator Over-Current Protection Circuit CPU Core Voltage Note: Although we have implemented protection circuit try to prevent any human operating mistake, there is still certain risk that CPU, memory, HDD, add-on cards 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. 61 AX4GER / AX4GER-N H a r d w a r e M o n i t or i n g Online Manual This motherboard implements a hardware monitoring system. As you turn on your system, this smart design will continue to monitor your system's working voltage, fan status and CPU temperature. If any of these systems' status goes wrong, there will be an alarm through the chassis external speaker or buzzer of motherboard (if existed) to warn the user.

We now bring you a comprehensive system detective utility. AOConfig is a Windows based utility with user-friendly interface 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. 63 AX4GER / AX4GER-N 3. This page presents the IDE devices information, such as the serial number, the manufacturer, the firmware version, and capacity. Online Manual 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, or even the latest 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. 64 AX4GER / AX4GER-N 3 3 0 0 F L o w E S R C a p a c i t or Online Manual The quality of low ESR capacitor (Low Equivalent Series Resistance) during high frequency operation is very important for the stability of CPU power. The idea of where to put these capacitors is another know-how that requires experience and detail calculation. Not only that, AX4GER / AX4GER-N implements 3300F capacitors, which is much larger than normal capacitor (1000 and 1500F) and it provides better stability for CPU power. 65 AX4GER / AX4GER-N Layout (Frequency Isolation Wall) Online Manual For high frequency operation, especially overclocking, layout is the most important factor to make sure chipset and CPU working in stable condition. The layout of this motherboard implements AOpen's unique design called " Frequency Isolation Wall". Separating each critical portion of motherboard into regions where each region operates in a same or similar frequency range to avoid cross talk and frequency interference between each region's operations and condition. [. . . ] You can find this bar code label on the outside packing or on the component side of PCB. For example: Part No. Serial No. Part No. P/N: 91. 88110. 201 is part number, S/N: 91949378KN73 is serial number. 113 AX4GER / AX4GER-N Mo d e l n a m e a n d B I O S v e r s i o n Online Manual Model name and BIOS version can be found on upper left corner of first boot screen (POST screen). For example: AX4GER-N R1. 20 Sep. 01. 2002 AOpen Inc. Award Plug and Play BIOS Extension v1. 0A Copyright © 2002, Award Software, Inc.
