This feature is very similar as Wake On Modem, but it goes through local area network. To use Wake On LAN function, you must
have a network card with chipset that supports this feature, and connect a cable from LAN card to motherboard WOL connector.
The system identification information (probably IP address) is stored on network card and because there is a lot of traffic on the
Ethernet, you need to install network management software, such as ADM, for the checking of how to wake up the system. Note
that, at least 600mA ATX standby current is required to support the LAN card for this function.

YYeeaarr 22000000 ((YY22KK))
Y2K is basically a problem of the identification of year code. To save storage space, traditional software uses only two digits for
year identification. For example, 98 for 1998 and 99 for 1999, but 00 will be confused with 1900 and 2000.
There is an RTC circuit (Real Time Clock) in conjunction with 128 bytes of CMOS RAM data in the chipset of the motherboard. The
RTC has only two digits and the CMOS has another 2 digits. Unfortunately, this circuit’s behavior is like this 1997# 1998 # 1999
# 1900, that means it may have the Y2K problem. Below is a diagram of how applications work with the OS, BIOS and RT C. In
order to keep the best compatibility in the PC industry there is a rule that applications must call the OS to get services and OS
must call the BIOS, and then only BIOS is allowed to access the hardware (RTC) directly.
Applications
There is a Tick Routine (that goes live around every 50m sec) in the BIOS to keep record of date/time information. In general the
BIOS, this Tick Routine does not update t he CMOS every time because the CMOS is a very slow device that degrades system
performance. The Tick Routine of the AOpen BIOS has 4 digits for year coding, as long as applications and the operating system

The quality of low ESR capacitor (Low Equivalent Series Resistance) during high frequency operation is very important for stability
of CPU power. The location of where to put these capacitors is anot her know-how that requires experience and detail calculation.
Based on CPU gets higher and higher working frequency, the CPU needs more power to work and this higher electric current will
cause higher temperature. As we know, higher temperature will reduce the components’ lifecycle. Hence, we use three-phase
power solution for this AMD Socket 462 platform motherboard for provides better CPU power supply solution to decrease
temperature issue and get more system reliability.

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.

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

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".
This section is dedicated to overclockers.
This high performance motherboard is designed for maximum 100MHz CPU bus clock. But it comes with clock generator of
150MHz when we design it to accommodate future CPU bus clock. Our lab test results shown that 150MHz is achievable when
proper setting and qualified components were presented, we feel quite comfortable overclocking to 150MHz. Not only that, this
motherboard has full-range (CPU core voltage) settings and an option to adjust CPU core voltage. The CPU clock ratio can be up
to 8x that supports almost all of Athlon/Duron CP Us in the future and provides flexibility for overclockers. For your reference, the
following configurations are what we feel comfortable at 150MHz bus clock.
But not guaranty.
Tip: Note that overclocking may also
cause thermal problem. Please make
sure that the cooling fan and the
heatsink were adequate to dissipate
excessive heat that's generated by
overclocking the CPU.
☺
Warning: The design of this product follows CPU and chipset vendor's
design guideline. Any attempts to push beyond product specification are
not recommended and you are taking your own risk to damage your
system or important data. Before doing overclocking, you must make sure
your components are able to tolerate such abnormal setting, especially
CPU, DRAMs, hard disks, and AGP cards.

AACC9977
Basically, AC97 specification separates sound/modem circuit to two parts, digital processor and a CODEC for analogy I/O they are
linked by AC97 link bus. Since digital processor can be put into motherboard main chipset, the cost of sound/modem onboard
solution can be reduced.
AACCPPII ((AAddvvaanncceedd CCoonnffiigguurraattiioonn && PPoowweerr IInntteerrffaaccee))
ACPI is the power management specification of PC97 (1997). It intends to save more power by taking full control of power
management to operating system and bypass BIOS
operating system (such as Windows 98). This is a bit similar as the PnP
power switch to control the power state transition.
AAGGPP ((AAcccceelleerraatteedd GGrraapphhiicc PPoorrtt))
AGP is a bus interface targeted for high-performance 3D graphic. AGP supports only memory read/write operation and
single-master single-slave one-to-one only. AGP uses both rising and falling edge of the 66MHz clock, for 2X AGP, the data
transfer rate is 66MHz x 4byte x 2 = 528MB/s. AGP is now moving to 4X mode, 66MHz x 4byte x 4 = 1056MB/s. AOpen is the first
company to support 4X AGP motherboards by both AX6C (Intel 820) and MX64/AX64 (VIA 694x), started from Oct 1999.

AATTAA ((AATT AAttttaacchhmmeenntt))
ATA is the specification of diskette interface. In 80’s, many software and hardware manufacturers instituted the ATA specification
together. The AT is meaning International Business Machines Corporation (IBM) personal computer/AT’s bus structure.
AATTAA//6666
ATA/66 uses both rising edge and falling edge but doubles UDMA/33 transfer rate. The data transfer rate is 4 times of the PIO
mode 4 or DMA mode 2, 16.6MB/s x4 = 66MB/s. To use ATA/66, you need special ATA/66 IDE cable.

MMKK3333 IIII // MMKK3333 IIII((AA)) OOnnlliinnee MMaannuuaall
AATTAA//110000
ATA/100 is a new IDE specification under developing. ATA/100 uses both rising edge and falling edge as ATA/66 but cl ock 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, t he s am e as ATA/66.
BBIIOOSS ((BBaassiicc IInnppuutt//OOuuttppuutt SSyysstteemm))
BIOS is a s et of assembly routine/prog ram that reside i n EPROM or Flash ROM. BIOS controls Input/output devices and other
hardware devices of motherboard. In general, to provide hardware independent portability, operation system and drivers is required
to access BIOS without directly access hardware devices.
BBuuss MMaasstteerr IIDDEE ((DDMMAA mmooddee))
The traditional PIO (Programmable I/O) IDE requires the CPU to involve in all the activities of the IDE access including waiting for
the mechanical events. To reduce the workload of the CPU, the bus master IDE device transfers data from/to memory without
interrupting CPU, and releases CPU to operate concurrently while data is transferring between memory and IDE device. You need
the bus master IDE driver and the bus master IDE HDD t o support bus m aster IDE mode.

The ECC mode needs 8 E CC 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.
EEDDOO ((EExxtteennddeedd DDaattaa OOuuttppuutt)) MMeemmoorryy
The EDO DRAM technology is actually very similar to FPM (Fast Page Mode). Unlike traditional FPM that tri-states the memory
output data to start the pre-charge activity, EDO DRAM holds the memory data valid until the next memory access cycle, that is
similar to pipeline effect and reduces one clock state.
EEEEPPRROOMM ((EElleeccttrroonniicc EErraassaabbllee PPrrooggrraammmmaabbllee RROOMM))

is different. Size of EEPROM is much smaller than flash ROM.
EEPPRROOMM ((EErraassaabbllee PPrrooggrraammmmaabbllee RROOMM))
Traditional motherboard stores BIOS code in EPROM. EPROM can only be erased by ultra-violet (UV) light. If BIOS has to be
upgraded, you need to remove EPROM from motherboard, clear by UV light, re-program, and then insert back.

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. Serial Bus Management provides overall configuration control of the serial bus in the form of optimizing
arbitration timing, guarantee of adequate electrical power for all devices on the bus, assignment of isochronous channel ID, and
notification of errors. There are two type of IEEE 1394 data transfer: asynchronous and isochronous. Asynchronous transport is the
traditional computer memory-mapped, load and store interface. Data requests are sent to a specific address and an
acknowledgment is returned. In addition to an architecture that scales with silicon technology, IEEE 1394 features a unique
isochronous data channel interface. Isochronous data channels provide guaranteed data transport at a pre-determined rate. This is
especially important for time-critical multimedia data where just-in-time delivery eliminates the need for costly buffering.
