Flash ROM CMOS Backup by EEPROM 57 AX4B-533 / AX4B -533N O v e r - c ur r e n t P r o t e c t i o n Online Manual The Over Current Protection is a popular implementation on ATX 3. 3V/5V/12V switching power supply. However, the new generation CPU uses different voltage with a regulator to transfer 12V to CPU voltage (for example, 2. 0V), and thus makes 5V over current protection useless. This motherboard is with switching regulator onboard supporting CPU over-current protection; in conjunction with 3. 3V/5V/12V power supply provide the full line over-current protection. 3. 3V (Protected by power supply) ATX Switching Power Supply 5V (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 and tried to prevent any human operating mistake, certain risks might still happen when CPU, memory, HDD or add-on cards installed on this motherboard is damaged due to component failure, human operating error or other unknown natural reasons. AOpen cannot guarantee that the protection circuit will always work perfectly. 58 AX4B-533 / AX4B -533N H a r d w a r e M o ni 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 monitor your system's working voltage, fan status and CPU temperature. If any of those systems' status goes wrong, there will be an alarm through the chassis external speaker or buzzer of motherboard (if having this function and enabled) to warn the user. Fan Fan Speed Detection CPU CPU Temperature CPU Voltage Circuit AOpen H/W Monitoring Utility Power System Voltage 59 AX4B-533 / AX4B -533N R e se t ta b l e F u s e Online Manual Traditional motherboard uses fuses to prevent Keyboard and USB port from over-current or shortage. These fuses are soldered onboard that when it is broken (function to protect motherboard), user cannot replace them and result in malfunction of motherboard. With expensive Resettable Fuse, the motherboard can be resumed back to normal function even after the fuse had done its protection job. Resettable Fuse 60 AX4B-533 / AX4B -533N 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. Moreover, AX4B-533 / AX4B-533N implements 3300F capacitors that have much larger capacity than normal capacitor (1000 and 1500f) and provide better stability for CPU power. 61 AX4B-533 / AX4B -533N Layout (Frequency Isolation Wall) Online Manual For high frequency operation, especially when overclocking, layout is the most important factor to make sure both chipset and CPU are 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, we can avoid cross talk and frequency interference between each region's operations and condition. The trace length and route must be calculated carefully. For example, the clock trace must be equal to length (not necessarily as short as possible) so that clock skew will be controlled within few a pico second (1/1012 Sec) Note: This diagram for example only; it may not be exactly the same as the motherboard you purchased. 62 AX4B-533 / AX4B -533N E nl a r g e d Al u m i n u m H e a t s i n k Online Manual Cool down CPU and Chipset are important for system reliability. Enlarged aluminum heat sink provides better heat consumption especially when you are trying to over-clock the CPU. 63 AX4B-533 / AX4B -533N Online Manual D ri v e r a n d U t i l i t y There are motherboard drivers and utilities included in AOpen Bonus CD. You don't need to install all of them in order to boot your system. But after you finish the hardware installation, you have to install your operation system first (such as Windows 98) before you can install any drivers or utilities. Please refer to your operation system's installation guide. Note: Please follow recommended procedure to install Windows 95 and Windows 98. 64 AX4B-533 / AX4B -533N A u t o - r u n Me n u f r o m B o n u s C D Di s c Online Manual You can use the auto-run menu of Bonus CD disc. Choose the utility and driver and select model name. 65 AX4B-533 / AX4B -533N I n s t a l l i n g I n t e l ® C hi p s e t S o f t w a r e I n s t a l l a t i o n U t i l i t y Online Manual Windows 95/98 cannot recognize this chipset, because they were released earlier than Intel 845 chipset. You can install Intel INF Update Utility from Bonus Pack CD auto-run menu to eliminate the "?" marks. 66 AX4B-533 / AX4B -533N I n s t a l l i n g I n t e l I A A Dr i v e r Online Manual You can install Intel IAA Driver to increase the performance of software applications and reduce PC boot times. [. . . ] You can find this bar code label on the outside packing, on PCI slot or on 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. 106 AX4B-533 / AX4B -533N 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). 01. 2002 AOpen Inc.
