[. . . ] Because transmission-line losses are proportional to current, capacitance is added to the circuit when possible, thus bringing the power factor as nearly as possible to 1. For this reason, large capacitors are frequently inserted as a part of power-transmission systems. 52 AX4T II-533 / AX4T II-533N Online Manual The power circuit of the CPU core voltage must be checked to ensure system stability for high speed CPUs (such as the new Pentium III, or when overclocking). A typical CPU core voltage is 2. 0V, so a good design should control voltage between 1. 860V and 2. 140V. That is, the transient must be below 280mV. Below is a timing diagram captured by a Digital Storage Scope, it shows the voltage transient is only 143mv even when maximum 18A current is applied. Note: This diagram is for example only; it may not be exactly the same as this motherboard. 53 AX4T II-533 / AX4T II-533N 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. The trace length and route must be calculated carefully. For example, the clock trace must be equal 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 look exactly the same with the motherboard you purchased. 54 AX4T II-533 / AX4T II-533N P ur e Al u m i n u m H e a t s i n k Online Manual Cool down CPU and Chipset is important for system reliability. Aluminum heat sink provides better heat consumption especially when you are trying to overclock. 55 AX4T II-533 / AX4T II-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 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. 56 AX4T II-533 / AX4T II-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. 57 AX4T II-533 / AX4T II-533N Eliminate "?" mark from Windows 95/98 Online Manual Windows 95/98 cannot recognize this chipset, because it was released before the Intel 850E chipset. You can install the Intel INF Update Utility from the Bonus Pack CD disc auto-run menu to eliminate the "?" marks. 58 AX4T II-533 / AX4T II-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 it in the AOpen Bonus Pack CD. 59 AX4T II-533 / AX4T II-533N I n s t a l l i n g O n b o a r d L A N Dr i v e r ( F o r A X 4 T I I - 5 3 3 N ) Online Manual This motherboard comes with an Intel® 10/100Mbps LAN controller. You can find the LAN driver from the Bonus Pack CD. 60 AX4T II-533 / AX4T II-533N I n s t al l i n g O n b o ar d A u d i o D r i ve r Online Manual This motherboard comes with a RealTek ALC201A chip. You can find the audio driver from the Bonus Pack CD auto-run menu. 61 AX4T II-533 / AX4T II-533N I n s t a l l i n g H a r d w a r e M o n i t or i n g U t i l i t y Online Manual You can install Hardware Monitoring Utility to monitor CPU temperature, fans and system voltage. The hardware monitoring function is automatically implemented by the BIOS and utility software. To install the software, double click "Setup. exe". The driver will be copied into Windows directory and an entry of "Hardware Monitor" in the start menu will be created. 62 AX4T II-533 / AX4T II-533N A C P I S u s p e n d t o H a r d Dr i v e Online Manual ACPI Suspend to Hard Drive is basically controlled by Windows operation system. It saves your current work (system status, memory and screen image) into hard disk, and then the system can be totally power off. [. . . ] The part number, serial number and BIOS version are also very helpful. Part Nu m b er an d Seri al Nu m b er The Part Number and Serial number are printed on bar code label. You can find this bar code label on the outside packing, on ISA/CPU slot or on component side of PCB. For example: Part No. Serial No. P/N: 91. 88110. 201 is part number, S/N: 91949378KN73 is serial number. 96 AX4T II-533 / AX4T II-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). 2002 AOpen Inc.
