These fuses are soldered onboard that when it is broken (did the job to protect motherboard), user still cannot replace it and the motherboard is still malfunction. With expensive Resettable Fuse, the motherboard can back to normal function after fuse did the protection job. 56 AK73(A)-V / AK73-V 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) is very important for the stability of CPU power especially during high frequency operation. The location of these capacitors requires well-experienced and precise calculation. 57 AK73(A)-V / AK73-V Online Manual The power circuit of the CPU core voltage must be checked to ensure system stability for high speed CPUs (such as some new generation CPUs whose clock values are higher than 1 GHz, or when overclocking). A typical CPU core voltage is 2. 0V, so a good design should control voltage between 1. 860V and 2. 140V. 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 for example only, it may not be exactly the same as the motherboard you purchased. 58 AK73(A)-V / AK73-V 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. 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 be exactly the same as the motherboard you purchased. 59 AK73(A)-V / AK73-V 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 disc. 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. 60 AK73(A)-V / AK73-V A u t or u n M e n u f r o m B o n u s C D Di s c Online Manual You can use the autorun menu of Bonus CD disc. Choose the utility and driver and select model name. 61 AK73(A)-V / AK73-V Installing Windows 95 1. First, don't install any add-on card except AGP card. Online Manual Install Windows 95 OSR2 v2. 1, 1212 or 1214 version and later with USB support. Otherwise, you need to install USBSUPP. EXE. 3. Install the VIA 4 in 1 driver, which includes VIA AGP Vxd driver, VIA ATAPI Vendor Support driver and VIA registry (INF) program. 4. Finally, Install other add-on cards and their drivers. 62 AK73(A)-V / AK73-V Installing Windows 98 1. First, don't install any add-on card except AGP card. Online Manual Enable USB Controller in BIOS Setup > Advanced Chipset Features > USB Controller, to make BIOS fully capable of controlling IRQ assignment. 3. Install the VIA 4 in 1 driver, which includes VIA AGP Vxd driver, IRQ Routing, VIA ATAPI Vendor Support driver and VIA registry (INF) program. Finally, Install other add-on cards and their drivers. 5. 63 AK73(A)-V / AK73-V Online Manual Installing Windows 98 SE, Windows ME & Windows2000 If you are using Windows 98 Second Edition, Windows Millennium Edition or Windows 2000, you do not need to install the 4-in-1 driver as the IRQ Routing Driver and the ACPI Registry are already incorporated into the operating system. Users with Windows 98 SE may update the VIA Registry INF and AGP drivers by installing them individually. for latest version of 4 in 1 driver: http://www. via. com/ 64 AK73(A)-V / AK73-V I n s t al l i n g VI A 4 i n 1 D r i ve r Online Manual You can install the VIA 4 in 1 driver (IDE Bus master (For Windows NT use), VIA ATAPI Vendor Support Driver, VIA AGP, IRQ Routing Driver (For Windows 98 use), VIA Registry (INF) Driver) from the Bonus Pack CD disc Autorun menu. Note: Installing this Bus Master IDE driver may cause Suspend to Hard Drive failure. Warning: If you want to uninstall the VIA AGP Vxd driver, please remove the AGP card driver first. Otherwise, the screen may go black at rebooting after the un-installation. 65 AK73(A)-V / AK73-V I n s t a l l i n g O n b o a r d S o u n d Dr i v e r Online Manual This motherboard comes with RealTek ALC201 chip; you can find the audio driver from the Bonus Pack CD disc auto-run menu. 66 AK73(A)-V / AK73-V 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.
