This chapter describes j umpers, connectors and hardware devices of this motherboard.
Note: Electrostatic discharge (ESD) can damage your processor, dis
drives, expansion boards, and other components. Always observe th
following precautions before you install a system component.
1.Do not remove a component from its protective packaging until yo
are ready to install it.
2.Wear a wrist ground strap and attach it to a metal part of the syste
unit before handling a component. If a wrist strap is not available,
maintain contact with the system unit throughout any procedure
requiring ESD protection.

You can clear CMOS to restore system default sett i ng. To clear the CMOS, follow the procedure
below.
1. Turn off the system and unplug the AC power.
2. Remove ATX power cable from ATX power connector.
3. Locate JP14 and short pins 2-3 for a few seconds.
4. Return JP14 to its normal setting by shorting pi ns 1-2.
5. Connect ATX power cable back to ATX power connector.
Tip: When should I Clear CMOS?
1. Boot fail because of overclocking…
2. Forget password…

This feature is very similar as Wake On Modem, but i t 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 LA N card to motherboard W O L connector. The system identification
information (probably IP address) is stored on network card and becaus e there is a lot of traffic on
the Ethernet, you need to install a 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.

This Motherboard implements EEPROM and a special circuit that allo ws you t o save your current
CPU and CMOS Setup configurations without the need of a battery. The RTC (real time clock) can
also keep running as long as the power cord is pl ugged. If you lose your CMOS data by accident ,
you can just reload the CMOS configurations from EEPROM and the system will recover as usual.
Tip: For your convenience, this motherboard is still shipped
with one Lithium (CR-2032) battery in the battery socket. If
you prefer to use battery, you can keep it in the socket. The
RTC will still keep running even power cord is removed.

The Over Current Protection was very popular im pl emented 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 protec tion useless. This motherboard
with switching regulator onboard support CPU over-c urrent protection, in conjunction with
3.3V/5V/12V power supply provide the f ul l l i ne over-current protection.

Y2K is basically a problem of the identificat i on of year code. To save storage space, traditional
software uses only two digits for year i dentification. For example, 98 f or 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 di agram of how applications work with the OS, BI OS and RTC.
In order to keep the best compat ibility 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.

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 the CMOS every time
because the CMOS is a very slow device which degrades system performance. The Tick Routine of
the AOpen BIOS has 4 digits for year coding, as long as applic ations and the operating system
follow the rule to get date/time information. There will be no Y2K problem (such as NSTL’s test
program). But unfortunatel y agai n, we found some test programs (such as Checkit 98) ac cesses

The power circuit of the CPU core voltage must be checked to ensure syst em stability for high
speed CPUs (such as the new Penti um III, or when overclocki ng). 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 i s applied.
