Note: Electros tatic d ischarge (ESD) c an dama ge your pr ocessor, d isk
drives, ex pa nsion boar ds , an d other comp on ent s . Always observe t he
following prec autions before you install a system component.

1.Do not remove a co mponent fro m its protect ive packag ing until you
are ready to ins t a ll it.

2.Wear a wr ist grou nd stra p and attac h it to a met al part of th e syst em
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 sy stem default setting. To
clear the CMOS, follow the procedure below.

1. Turn off the syst em an d un plug the AC power.

2. Remove ATX power cable from connector PWR2.

3. Locate JP14 and short pins 2-3 for a few seconds.

4. Return JP14 to its normal setting by shorting pins 1-2.

5. Connect ATX power cable back to connector PWR2.

Tip: When should I Clear CMOS?

1. Boot fail because of overclocking…

2. Forget password…

3. Troubleshooting…

DDIIMMMM SSoocckkeett

This moth erb oard has three 1 68- pin DIMM socke ts that allow you to install PC133 memory up to

1.5GB. Only SDRAM is supported.

Pin 1

Tip: The driving capability of new generation chipset
is limited due to the lack of a memory buffer (to
improve performance). This makes DRAM chip count
an important factor to take into consideration when
you install DIMMs. Unfortunately, there is no way that
the BIOS can identify the correct chip count, you
need to calculate the chip count by yourself. The

DIMM1
DIMM2
DIMM3

simple rule is: By visual inspection, use only
DIMMs which are less than 18 ch ips..

DIMM can be single side or double side, it has 64 bit data and 2 or 4 clock signals. We strongly
recommend choosing 4-clock SDRAM for its reliability

Tip: To identify 2-clock and 4-clock DIMM, you may
check if there are traces connected to the golden
finger pins 79 and 163 of the SDRAM . If th ere are
traces, the SDR AM is probably 4-clock; otherwise, it
is 2-cloc k .

Tip: To identify single-side or double-side DIMM,
check golden finger pin 114 and pin 129. If there are
traces connected to pin 114 and pin 129, the DIMM
is probably double-side; otherwise, it is single-side.

IDE1 is also k nown as th e primar y channel and IDE2 as th e second ary c hannel. Each chan nel
supports two IDE devices that make a total of four devices. In order to work together, the two
devices on each channel must be set differently to master and s lav e mod e. E ither on e can b e th e
hard disk or the CDROM. The setting as master or slave mode d epends on the jumper on your IDE
device, so please refer to your hard disk and CDROM manual accordingly.

Warning: Th e sp ecification of the ID E ca ble is a
maximu m of 46cm (18 inches) , make sure your cable
does not exceed this length.

Tip: For better signal quality, it is recommended t o
set the far end side device to m as ter m ode and
follow the suggested sequence to install your new
device. Please refer to above di agram.

YYeeaarr 22000000 ((YY22KK))

Y2K is bas ically a problem of the identific ation of year cod e. To save storage space, tr aditional
softwar e uses onl y two digits f or year identif icati on. For exam ple, 98 for 1998 and 99 f or 1999, but
00 will be confused with 1900 and 2000.

There is an RTC cir c u it ( Real Time C l oc k) in conjunc t i on with 12 8 b y tes of CMO S R A M d at a in t he
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, th at means it may
have the Y2K pr oblem. Below is a diagr am of h ow applications w ork wi th the OS, BIOS and RTC. In
order to keep th e best c omp atibility in the PC i nd us t r y there is a rule that applic ations mus t call the
OS to get services and OS must call the BIOS, and then only BIOS is allowed to access the
hardwa re (RTC) d irectly.

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 c oding, as long as applic at ions and the operati ng system
follow t he rule to get date/t ime infor mation. Th ere will be no Y2K pr oblem (suc h as NSTL’s tes t
program) . But unfortu nately ag ain, we found some t est prog rams (s uch as C heckit 98) acc esses

The quality of low ESR capacitor (Low Equivalent Series Resistance) during high frequency

is another know-how that requires experience and detail calculation.

As a leadin g manuf actur er in mother board in dustr y, AOpen always listens to what cust omers want
and develop products to fit different user's requirements. Reliability, compatibility, leading

above mentioned design criteria, there are power users who are always seeking to push the
limitati on of th e s yst em per formanc e by overc l oc k ing which we call them "Overclock er".

This section is dedicated to Overclockers.
This high performance motherboard is designed for maximum 133MHz CPU bus clock. But it

Warning: The design of this product follows CPU and chipset vendor's

BIOS is a set of assembly rout in e/program th at r es id e in EPROM or Flash ROM. BIOS controls

The traditional PIO (Programmable I/O) IDE requires the CPU to involve in all the activities of the
