[. . . ] 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 12V (Protected by power supply) 3. 3V (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. 51 MK77-333 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 AOpen Hardware Monitoring Utility to warn the user. Fan Fan Speed Detection AOpen H/W Monitoring Utility CPU CPU Temperature CPU Voltage Circuit Power System Voltage 52 MK77-333 Res ett a ble Fuse Online Manual Traditional motherboard has fuse for Keyboard and USB port to prevent over-current or shortage. These fuses are soldered onboard that user cannot replace it when it is damaged (did the job to protect motherboard), and the motherboard remains malfunction. With expensive Resettable Fuse, the motherboard can resume back to normal function after fuse had done its protection job. Resettable Fuse 53 MK77-333 220 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. Not only that, this motherboard implements 2200F capacitor, which is much larger than normal capacitor (1000 or 1500F) and it provides better stability for CPU power. 54 MK77-333 L a y o u t ( F r e q u e n c y I s o l a t i o n Wa l l ) 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 12 within few a pico second (1/10 Sec) Note: This diagram is for example only, it may not exactly be the same diagram of this motherboard. 55 MK77-333 Enlarged Aluminum Heatsink Online Manual Cool down CPU and Chipset is important for system reliability. Enlarged aluminum heat sink provides better heat consumption especially when you are trying to over clocking the CPU. 56 MK77-333 Online Manual D r iv e r a n d Ut i li 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. 57 MK77-333 A u t o - r u n Me n u f r o m B o n u s C D D i s c Online Manual You can use the auto-run menu of Bonus CD disc. Choose the utility and driver and select model name. 58 MK77-333 I ns t a ll i n g L A N D ri v e r Online Manual Introduction: ------------This document describes the procedure to install Windows 95 (Golden version), Win95A, OSR2, Windows 98/98 SE, Windows 2000, Windows ME, Windows NT v4. 0 driver for Realtek RTL8139 PCI Fast Ethernet adapter. [Windows 95 (Golden version), Win95A and OSR2] Installing driver procedure on Microsoft Windows 95 : ----------------------------------------------------1. Ask you to select which driver you want to install, select "Driver from disk provided by hardware manufacturer". Specify the setup file pathname [CD-ROM]:Driver\LAN\RTL8100\Windows\Win95\WIN95A (for Windows 95 and Win95A) or [CD-ROM]:Driver\LAN\RTL8100\Windows\Win95 (for Windows 95 OSR2). Windows 95 will appear some messages to insert Windows 95 system disk to complete setup step. Windows 95 will finish the other installation procedure automatically, then you restart the system. 59 MK77-333 [Windows 98, Windows 98 SE, Windows2000, Windows ME, Windows XP] Online Manual Installing driver for Win98/Win98 SE/Windows2000/Windows ME/Windows XP : ------------------------------------------------------------------1.
