K 57 AX4L / AX4L -N Ba t t e r y - l e s s a nd Long Li f e De s i gn Online Manual This Motherboard implements Flash ROM and a special circuit that allows you to save your current CPU and CMOS Setup configurations without the need of a 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. 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 58 AX4L / AX4L -N CP U O v e r - c ur r e nt P r ot e c t i on 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 5V 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. 59 AX4L / AX4L -N H a r d w a r e Mo n i t o r 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.

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 ins talled on your motherboard. 61 AX4L / AX4L -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 98S E/ME, NT4. 0/2000, or even th e latest Windows XP. Please be informed that AOconfig can only be operated in a system equipped with an AO pen motherboard. Meanwhile, all applications must be closed before starting AO config. 62 AX4L / AX4L -N Resetable Fuse Online Manual Traditional motherboard has fuse for Keybo a rd and USB port to prevent over-current or shortage. These fuses are soldered onboard that when it is broken (function as protecting the motherboard), user still cannot replace it and the motherboard is still malfunctioning. With expensive Resetable Fuse, the motherb oard can be resumed back to normal function after the fuse had done its protection job. Resettable Fuse 63 AX4L / AX4L -N 220 0 F L o w ES R Ca p a c it o r 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.
