Page 53: Over-Current Protection
The Over Current Protection was very popular implemented on ATX 3.3V/5V/12V switching power supply. However, the new generation CPU uses different voltage that has regulator to transfer 5V to CPU voltage (for example, 2.0V), and makes 5V over current protection useless. This motherboard is with switching regulator onboard supports CPU over-current protection; in conjunction with 3.3V/5V/12V power supply provide the full line over-current protection. - Page 54 CPU, memory, HDD, add-on cards installed on this motherboard may be damaged because of component failure, human operating error or unknown nature reason.

Page 57: Low Esr Capacitor
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. - Page 58 AK73(A)-V / AK73-V Online Manual 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.

Page 80: Bios Upgrade
By doing so, you are taking a risk of BIOS flash failure. If you indeed intent on upgrading, PLEASE BE SURE to use the right BIOS revision for the right motherboard model. AOpen Easy Flash is a little different than traditional flash method. The BIOS binary file and flash routine are linked together and you simply run a single commend to complete the flash process. - Page 81 Below are the steps for easy flashing procedures: (applies for Award BIOS ONLY) 1. Download new BIOS upgrade file from AOpen's web site. For example, AK73AV102.ZIP. 2. Run shareware PKUNZIP (http://www.pkware.com/) which supports miscellaneous operation systems to extract the binary BIOS file and the flash utility.

Page 82: Overclocking
As a leading manufacturer in motherboard industry, AOpen always listens to what customers want and develop products to fit different user's requirements. Reliability, compatibility, leading technology and friendly features are our basic goals when designing motherboards. Other than above mentioned design criteria, there are power users who are always seeking to push the limitation of the system performance by overclocking which we call them "Overclocker". -

Page 85: Amr (Audio/Modem Riser)
Unlike ACPI, BIOS controls most APM power management functions. AOpen Suspend to Hard Drive is a good example of APM power management. ATA is the specification of diskette interface. In 80’s, many software and hardware manufacturers instituted the ATA specification together. -
Page 86: Ata/100
ATA/100 is a new IDE specification under developing. ATA/100 uses both rising edge and falling edge as ATA/66 but clock cycle time is reduced to 40ns. The data transfer rate is (1/40ns) x 2 bytes x 2 = 100MB/s. To use ATA/100, you need special 80-wire IDE cable, the same as ATA/66. -
Page 87: Codec (Coding And Decoding)
Normally, CODEC means a circuit that can do digital to analog conversion and also the analog to digital conversion. It is part of AC97 sound/modem solution. DDR SDRAM utilizes the existing DRAM infrastructure and technology while doubling the nominal bandwidth available to systems in an easy to design and simple to adopt way. -
Page 88: Ecc (Error Checking And Correction)
The ECC mode needs 8 ECC bits for 64-bit data. Each time memory is accessed; ECC bits are updated and checked by a special 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. -
Page 89: Ev6 Bus
Flash ROM can be re-programmed by electronic signals. It is easier for BIOS to upgrade by a flash utility, but it is also easier to be infected by virus. Because of increase of new functions, BIOS size is increased from 64KB to 256KB (2M bit). AOpen AX5T is the first board to implement 256KB (2Mbit) Flash ROM. -
Page 90: Fsb (Front Side Bus) Clock
FSB Clock means CPU external bus clock. CPU internal clock = CPU FSB Clock x CPU Clock Ratio See SMBus. IEEE 1394 is a low-cost digital interface originated by Apple Computer as a desktop LAN and developed by the IEEE 1394 working group. -
Page 91: Parity Bit
The parity mode uses 1 parity bit for each byte, normally it is even parity mode, that is, each time the memory data is updated, parity bit will be adjusted to have even count "1" for each byte. When next time, if memory is read with odd number of "1", the parity error is occurred and this is called single bit error detection. -
Page 92: Pc-1600 Or Pc-2100 Ddr Dram
Based on FSB frequency, the DDR DRAM has 200MHz and 266MHz two type of working frequency. Because of DDR DRAM data bus is 64-bit, it provides data transfer bandwidth up to 200x64/8=1600MB/s, and 266x64/8=2100MB/s. Hence, the PC-1600 DDR DRAM is working with 100MHz and PC-2100 DDR DRAM is working with 133MHz FSB frequency. Bus for the internal connection of peripheral devices, high-speed data channel between the computer and expansion card. -
