Chapter 2
Hardware Installation
This chapter gives you a step-by-step procedure on how to install your system.
Follow each section accordingly.
Caution: Electrostatic discharge (ESD) can
damage your processor, disk drives, expansion
boards, and other components. Always
observe the following precautions before you
install a system component.
1. Do not remove a component from its
protective packaging until you are ready
to install it.
2. Wear a wrist ground strap and attach it to
a metal part of the system unit before
handling a component. If a wrist strap is
not available, maintain contact with the
system unit throughout any procedure
requiring ESD protection.

2.2 Jumpers
With the help of Celeron PPGA VID signal and SMbus, this motherboard is
jumper-less design.
2.2.1 Selecting the CPU Frequency
Celeron PPGA VID signal and SMbus clock generator provide CPU voltage
auto-detection and allow user to set CPU frequency through CMOS setup, no
jumper or switch is needed. The correct CPU information is saved into
EEPROM, with these technologies, the disadvantages of Pentium base jumperless design are eliminated. There will be no worry of wrong CPU voltage
detection and no need to re-open the housing if CMOS battery loss.
The CPU frequency selection is set by going into:
BOIS Setup à Frequency/Voltage Control à CPU FSB
(The possible setting is 66.8, 72, 75, 83.3, 90, 95, 100.2, 105, 107, 110, 112,
114, 117, 119, 121, 124, 125, 127, 129, 130, 133.6, 136, 138, 140, 145, 150,
and 155 MHz.)
BOIS Setup à Frequency/Voltage Control à CPU Ratio
(The possible setting is 3.0x, 3.5x, 4x, 4.5x, 5x, 5.5x, 6x, 6.5x, 7x, 7.5x, and 8x)
Core frequency = CPU Ratio * CPU FSB
INTEL Celeron PPGA CPU Core Frequency CPU Ratio CPU FSB
Celeron PPGA 300A 300MHz= 4.5x 66MHz
Celeron PPGA 333 333MHz= 5x 66MHz
Celeron PPGA 350 350MHz= 3.5x 100MHz
Celeron PPGA 366 366MHz= 5.5x 66MHz
Celeron PPGA 400 400MHz= 6x 66MHz
Celeron PPGA 433 433MHz= 6.5x 66MHz
2-4
Warning: INTEL 810 chipset supports a maximum of 100MHz
CPU FSB, the higher clock settings are for internal test only.
These settings exceed the specification of the chipset, which
may cause serious system damage.

(default)
The procedure to clear CMOS:
1. Turn off the system and unplug 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.
6. Turn on the system power.
7. Press during bootup to enter the BIOS Setup Utility and specify a
new password, if needed.
Tip: If your system hangs or fails to boot because of overclocking, please clear CMOS and the system will go back to
the default setting (233MHz or 350MHz).
Tip: If your system hangs or fails to boot because of overclocking, simply use <Home> key to restore to the default
setting. By this smart design, it would be more convenient to
clear CPU frequency setting. For using this function, you just
need to press <Home> key first and then press Power button

2.3.10 IDE Hard Disk and CD ROM
This mainboard supports two 40 pin IDE connectors marked as IDE1 and

each channel supports two IDE devices that make total of four devices.
In order to work together, the two devices on each channel must be set
differently to master and slave mode, either one can be hard disk or CDROM.
The setting as master or slave mode depends on the jumper on your IDE
device, please refer to your hard disk and CDROM manual accordingly.
Connect your first IDE hard disk to master mode of the primary channel. If you
have second IDE device to install in your system, connect it as slave mode on
the same channel, and the third and fourth device can be connected on
secondary channel as master and slave mode respectively.

2.4 Configuring the System Memory
The DIMM type supported is PC100
SDRAM (Synchronous DRAM) only.
This motherboard has two 168-pin
DIMM (Dual-in-line Memory Module)
sockets that allow you to install system
memory up to 512MB.
Pin1
DIMM modules can be identified by the following factors:
I. Size: single side, 1Mx64 (8MB), 2Mx64 (16MB), 4Mx64 (32MB), 8Mx64
(64MB), 16Mx64 (128MB), and double side, 1Mx64x2 (16MB), 2Mx64x2
(32MB), 4Mx64x2 (64MB), 8Mx64x2 (128MB).
Tip: Here is a trick to check if your DIMM is
single-side or double-side -- if there are traces
connected to golden finger pin 114 and pin 129 of
the DIMM, the DIMM is probably double-side;
otherwise, it is single-side. The following figure is
for your reference.
Pin 129
II. Speed:
normally marked as -12, which means the clock cycle time is 12ns and
maximum clock of this SDRAM is 83MHz. Sometimes you can also find the
SDRAM marked as -67, which means maximum clock is 67MHz.
2-20
Pin 114
Hardware Installation
III. Buffered and non-buffered: This motherboard supports non-buffered
DIMMs. You can identify non-buffered DIMMs and buffered DIMMs
according to the position of the notch, following figure is for your reference:
Reserved
non-buffered
buffered
Because the positions are different, only non-buffered DIMMs can be
inserted into the DIMM sockets on this motherboard. Although most of
DIMMs on current market are non-buffered, we still suggest you to ask your
dealer for the correct type.
IV. 2-clock and 4-clock signals: Although both of 2-clock and 4-clock signals
are supported by this motherboard, we strongly recommend choosing 4clock SDRAM in consideration of reliability.
Tip: To identify 2-clock and 4-clock SDRAM, you
may check if there are traces connected to golden
finger pin 79 and pin 163 of the SDRAM. If there
are traces, the SDRAM is probably 4-clock;
Otherwise, it is 2-clock.
There is no jumper setting required for the memory size or type. It is
automatically detected by the system BIOS, and the total memory size is to add
them together. The maximum is 512MB.
Total Memory Size = Size of DIMM1 + Size of DIMM2

Tip: 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.
