With expensive Resetable Fuse, the motherboard can be resumed back to normal function even after the fuse had done its protection job. Resetable Fuse...
CPU power. The idea of where to put these capacitors is another know-how that requires experience and detail calculation. Not only that, MX46U2-GN / MX46-533GN implements 3300μF capacitors, which is much larger than normal capacitor (1000 & 1500μF) and it provides better stability for CPU power.
Page 49
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.
Most BIOS setting of this model had been optimized by AOpen’s R&D engineering team. But, the default setting of BIOS still can’t fine-tune the chipset controlling the entire system.

Basically, AC97 CODEC is the standard structure of PCI sound card. As we know, computer is digital-based, but music is based on analog-based. Therefore, there must be a process to turn digital into analog during the last stage processing of sound in computer. Hence, the component on sound card that play this important task is what we called CODEC.
The main function of AGP simply put is to tell monitor what screen information had to be shown, a visual transmission device actually. With the rapid developing of AGP card, we can see that it had been developed from single colorful AGP card to 2D and 3D graphic.
drive controller and the computer's motherboard. Two drives (master and slave) are supported. The ATA specification allows the drive to connect directly to the ISA bus on the computer. ATA transfer rate then had been developed to 133MB /Sec and would come out with fastest rate later (please refer to Serial ATA).
also could be encrypted with pin code. With hopping rate of 1600 hops per second, it’s difficult to be intercepted and are less interrupted by electromagnetic wave. The CNR specification provides the PC industry the opportunity to deliver a flexible and cost reduced method of implementing LAN, home networking, DSL, USB, wireless, audio and modem subsystems widely used in today's "connected PCs".
algorithm. The ECC algorithm has the ability to detect double-bit error and automatically correct single-bit error while parity mode can only detect single-bit error. Also known as E PROM. Both EEPROM and Flash ROM can be re-programmed by electronic signals, but the interface technology is different.
FC means Flip Chip, FC-PGA is a package of Intel for Pentium III for 0.18µm process CPU, which can be plugged into SKT370 socket. After FC-PGA, FC-PGA2 is the package for 0.13µm process CPU developed by Intel, which can be plugged into SKT423/478 socket as well.
IEEE 1394, which also called Firewire, is a serial data transfer protocol and interconnection system. The main feature of the Firewire that assures its adoption for the digital video and audio (A/V) consumer application is its low cost. Fire wire interface is capable of supporting various high-end digital A/V applications, such as consumer A/V device control and signal routing, Digital Video (DV) editing, home networking, and more than 32 channels of digital mixing.
Developed by Intel, Peripheral Component Interconnect (PCI) is a local bus standard. A bus is a channel used to transfer data to (input) and from (output) a computer and to or from a peripheral device. Most PCs have a PCI bus usually implemented at 32-bits providing a 33 MHz clock speed with a throughput rate of 133 MBps.
PSB Clock means the external bus clock of CPU. CPU internal clock = CPU PSB Clock x CPU Clock Ratio A DRAM technology developed by Rambus Corporation*, to achieve high speed of memory through the use of multiple channels in parallel by 16-bits.
The Serial ATA specification is designed to overcome speed limitations while enabling the storage interface to scale with the growing media rate demands of PC platforms. Serial ATA is to replace parallel with the compatibility with existing operating systems and drivers, adding performance headroom for years to come. It is developed with data transfer rate of 150 Mbytes/second, and 300MB/s, 600M/bs to come.
recognize the change. USB 2.0, which supports data transfer rates of 480 Mbps, has been widely used in motherboard these days. NEC’s Virtual Channel Memory (VCM) is a new DRAM core architecture that dramatically improves the memory system’s ability to service multimedia requirements.
