HARDWARE INSTALLATION
2.1 Central Processing Unit: CPU
The mainboard operates with Cyrix®GXM/GX-LV processor. The
mainboard uses a CPU socket called Socket 7 for easy CPU installation. The
CPU should always have a Heat Sink and a cooling fan attached to prevent
overheating.
3. Press the lever down to
complete the installation.
2. Locate Pin 1 in the socket
and look for the white dot or
cut edge in the CPU. Match
Pin 1 with the white dot/cut
edge. Then, insert the CPU.
It should insert easily.

from the socket. Then, raise
the lever up to a 90-degree
angle.

1. The Jumper Switch JCKM1 (1-2, 3-4, and 5-6) is used to set the Core/Bus
(Fraction) ratio of the CPU. The actual core speed of the CPU is the Host
Clock Frequency multiplied by the Core/Bus ratio. For example:
If CPUClock = 33.3MHz
Core/Bus ratio = 6
then CPU core speed = Host Clock x Core/Busratio
= 33.3MHz x 6
= 200MHz

2. The jumper switch JP2 (1-2, 3-4)is used to adjust the CPU clock frequency.

2.1-4 Fan Power Connector: JFAN1
This connector support system cooling fan with +12V. It supports three pin
head connector. When connecting the wire to the connector, always take
note that the red wire is the positive and should be connected to the +12V,
the black wire is Ground and should be connected to GND. If your
mainboard had a System Hardware Monitor chipset on-board, you must use
a specially designed fan with speed sensor to take advantage of the CPU fan
control.
Note: For fans with speed sensor, every rotation of the fan will send out 2
pulses. System Hardware monitor will count and report the fan
rotation speed.

2.2 Clear CMOS Jumper: JBAT1
A battery must be used to retain the mainboard configuration in CMOS
RAM. If you use the on-board battery, you must short 1-2 pins of JBAT1
to keep the CMOS data.

Note: You can clear CMOS by shorting 2-3 pin, while the system is off.
Then, return to 1-2 pin position. To be able to clear the CMOS, you
need to unplug the power plug of the system, because there’s a 3V
standby power for the chipset which is provided by the power
supply. Otherwise, the CMOS will not be cleared.

2.3 Memory Installation
2.3-1 Memory Bank Configuration
The mainboard supports a maximum of 64MB of memory : It provides one
168-pin DIMMs (Double In-Line Memory Module) sockets. It supports 8
MB to 64 Mbytes DIMM memory module. The memory module can only
support SDRAM(Synchronous DRAM) MODE DRAM.
DIMM1(Bank1)
There are two kinds of DIMM specification supported
by this mainboard: PC100 and PC66. If you use
66MHz CPU Bus Frequency, these two DIMM Specs. is
supported. If you use 100 MHz CPU Bus Frequency,
only PC100 DIMM Specs. is supported.

A. HowtoinstallaDIMMModule
1. The DIMM slot has a two Notch Key “VOLT and DRAM”, so the
DIMM memory module can only fit in one direction.
2. Insert the DIMM memory module vertically into the DIMM slot.
Then push it in.
3. The plastic clip at the side of the DIMM slot will automatically
close.
