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.

1. Pull the lever sideways away
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.

2.1-3 CPU Voltage Setting: SW1
To adjust the voltage setting of the CPU, you must know the specifications
of your CPU (always ask the vendor for CPU spec.).

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.
