This motherboard is with switching regulator onboard supports CPU over-current protection; in conjunction with 3.
MX4B Online Manual H a r d w a r e M o ni t o r i n g 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.
MX4B Online Manual R e se t ta b l e F u s e Traditional motherboard has fuse for Keyboard 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 Resettable Fuse, the motherboard can be resumed back to normal function after the fuse had done its protection job.
MX4B Online Manual 2 2 0 0 μ F L o w E S R C a p a c i t or 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, MX4B implements 2200μF capacitors, which is much larger than normal capacitor (1000 & 1500μf) and it provides better stability for CPU power.
MX4B 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.
MX4B Online Manual Layout (Frequency Isolation Wall) 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”.

EV6 bus uses both rising and falling clock edge to transfer data, similar as DDR SDRAM or ATA/66 IDE bus. EV6 Bus Speed = CPU external bus clock x 2. For example, 200 MHz EV6 bus is actually using 100 MHz external bus clock, but the equivalent speed is 200 MHz. F C C D o C ( De c l a r a t i o n o f C o n f o r m i ty ) The DoC is component certification standard of FCC EMI regulations.
MX4B Online Manual F S B ( F r o n t S i d e B u s ) C l oc k FSB Clock means CPU external bus clock. CPU internal clock = CPU FSB Clock x CPU Clock Ratio I2C Bus See SMBus. IE EE 1 39 4 IEEE 1394 is a low-cost digital interface originated by Apple Computer as a desktop LAN and developed by the IEEE 1394 working group. The IEEE 1394 can transport data at 100, 200 or 400 Mbps. One of the solutions to connect digital television devices together at 200 Mbps.
MX4B Online Manual P BS R A M ( P i p e l i n e d B u r s t S R A M ) For Socket 7 CPU, one burst data read requires four QWord (Quad-word, 4x16 = 64 bits). PBSRAM only needs one address decoding time and automatically sends the remaining QWords to CPU according to a predefined sequence. Normally, it is 3-1-1-1, total 6 clocks, which is faster than asynchronous SRAM. PBSRAM is often used on L2 (level 2) cache of Socket 7 CPU. Slot 1 and Socket 370 CPU do not need PBSRAM.

P nP ( P l u g a n d P l a y ) The PnP specification suggests a standard register interface for both BIOS and operating system (such as Windows 95).
MX4B Online Manual R I M M ( Ra m b u s I n l i n e M e m o r y M o d u l e ) 184-pin memory module that supports RDRAM memory technology. A RIMM memory module may contain up to maximum of 16 RDRAM devices. S D R A M (S y nc h r o n o us D R A M ) SDRAM is one of the DRAM technologies that allow DRAM to use the same clock as the CPU host bus (EDO and FPM are asynchronous and do not have clock signal). It is similar as PBSRAM to use burst mode transfer.
MX4B Online Manual S M B us ( S y s te m Ma n a g e m e n t B us ) SMBus is also called I2C bus. It is a two-wire bus developed for component communication (especially for semiconductor IC). For example, set clock of clock generator for jumper-less motherboard. The data transfer rate of SMBus is only 100Kbit/s, it allows one host to communicate with CPU and many masters and slaves to send/receive message.
MX4B Online Manual U S B ( U n i v e rs a l S e r i a l B us ) USB is a 4-pin serial peripheral bus that is capable of cascading low/medium speed peripherals (less than 10Mbit/s) such as keyboard, mouse, joystick, scanner, printer and modem. With USB, the traditional complex cables from back panel of your PC can be eliminated.
MX4B Online Manual T r ou b l e s h o o t i n g If you encounter any trouble to boot you system, follow the procedures accordingly to resolve the problem. Start Turn off the power and unplug the AC power cable, then remove all of the add-on cards and cables, including VGA, IDE, FDD, COM1, COM2 and printer. Make sure if all jumper settings are correct.
MX4B Online Manual Continue Install the VGA card. Then connect your monitor and keyboard. Turn on the power Yes and check if the power supply and CPU fan work properly. No The problem is probably caused by power supply or motherboard failure. Please contact your reseller or local distributor for repairing.
MX4B Online Manual Continue No Check if there is display? Perhaps your VGA card or monitor is defective. Yes Press and key at the same time, hold them and then press to reboot the system. No Check if the system reboots? Yes Next 86 It is very possible that your keyboard is defective.
MX4B Online Manual Continue During system rebooting, press to enter BIOS setup. Choose “Load Setup Default”. Turn off the system and re-connect IDE cable. Check if the system can No reboot successfully? Yes Re-install the operating system such as Windows 98. End 87 The problem should be caused by the IDE cable or HDD itself.
