3Chapter 1Introduction of 866AS ULTRA /866AS ULTRA RAIDMotherboard1-1 Feature of motherboardThe 866AS ULTRA /866AS ULTRA RAID motherboard is design for use AMDAthlon/Duron 200MHZ /266MHz (Double Data Rate) Front Side Bus FrequencyCPU, which utilize the Socket-A design and the memory size expandable to 3.0GB.This motherboard use the newest VIA KT266A chipset which provides betterperformance than KT266 chipset, whose 133MHz/266MHz (Double Data Rate)Front Side Bus frequency and 266MHz memory interface delivers a clear upgradepath to the future generation of 266MHz processors and PC-1600/PC-2100 DDRDRAM. The 866AS ULTRA /866AS ULTRA RAID motherboard offers ULTRAATA 100 to provide speedier HDD throughout that boosts overall systemperformance.866AS ULTRA RAID including IDE RAID chipset and added extra 2 channel IDEinterface supports either ATA100, or RAID0 (striping), RAID1 (mirroring) function.Use RAID0 function it can increasing data storage performance, use RAID1 functionit can protect data which save in hard disk drive.These motherboards also has an integrated AC’97 2.1 CODEC on board which isfully compatible with Sound Blaster Pro that gives you the best sound quality andcompatibility.For those wanting even greater graphic performance, an AGP 4X slot is included onthe board.With USB control as well as capability of expanding to 6 USB function ports, the866AS ULTRA /866AS ULTRA RAID meet future USB demand also thismotherboard has built-in hardware monitor function. This will monitor and protectyour computer. 866AS ULTRA integrated Recovery Genius in BIOS protected yourhard disk from virus crash hard disk data.In 866AS ULTRA /866AS ULTRA RAID we design in CPU Vcore Voltage, System3.3V Voltage, DDR memory 2.5V Voltage, AGP 1.5V/3.3V Voltage those canminor adjustable in BIOS setup. This design can let users approach over clockdemand and also can make system more stable. The 866AS ULTRA /866ASULTRA RAID motherboard provides special function in BIOS Setup to setting CPUHost clock step by step increasing let users to approach over clocking, and specialdesign in hardware to protect BIOS from virus crash BIOS data.866AS ULTRA /866AS ULTRA RAID provides high performance & meets futurespecification demand. It is really wise choice for your computer.
