Note: 1. Make sure that the SDRAM module not only has to

be 168 pin DIMM but designed for 3.3V SDRAM as
well. Double check with the SDRAM supplier before
install any SDRAMs. The mainboard manufacturer
has no obligation to any damage of the board by using
the incorrect specification of SDRAM.

2. Pentium MMX (P55C), Cyrix 6x86L/6x86MX (M2),
and AMD K6 are dual voltage CPUs. JP7 must be
set correctly (refer to page 4). Check with your CPU
supplier for CPU voltage specification.

Mainboard Setting for Pentium MMX-166

The settings of the following figure is for the Pentium MMX­166 with the 256K cache. To get the best cooling effect, make
sure that the airflow from the CPU fan is facing the heatsink.
(MMX is dual voltage CPU, do not use this setting if CPU is
not MMX or 6x86L.)

*: These settings are not listed on PCB text.

Note: 1. Refer to the table above to choose the correct voltage

for the CPU everytime that you install a CPU.

2. K6-233 (or higher) has two kinds of
specifications: 3.2V or 2.1V which depends on
its processor. Refer to the CPUÕs surface
description.

3. Make sure that your JP7 is matched with the CPU
voltage, otherwise will damage the CPU or make the
system unstable.

4. When the new CPU is announced and is not listed
on this manual, please refer to the above table, select
the correct voltage setting for it.

This connector connects to the hard disk activity indicator
light on the case.

Infrared Port Module Connector (J1 pin6–10)

The system board provides a 5-pin infrared connectorÑIR1
as an optional module for wireless transmitting and
receiving. Pin 1 through 5 are Transmit, GND, Receive

(low speed), Receive (high speed), and Vcc, respectively.
