 In Dual voltage CPU, you only need to set up Vcore. Just “Open” JP1
and “Short” JP2, VI/O will supply 3.3V automatically.
 Remember to make sure CPU voltage set up is 100% correct by
referring to Page 11 and Page 12. Any voltage error setup happened in
Dual Voltage CPU will cause system unstable or doesn’t work, or even
worse is that it will burn out your CPU.

 Switch voltage is applied,
making the temperature lower
and voltage steadier.
 All the voltage specifications
adopted here are the averages
of the working voltage
suggested by t
he CPU makers,
to make any CPU applied work
with the best performance.
 In Single voltage CPU
VI/O=Vcore.

 The CPU type default setting is
Intel Pentium 166MHz=66 MHz
＊2.5.
 When a CPU with 75MHz is
applied, the PCI Bus CLK output
becomes 37MHz. Under this
circumstance, some VGA cards
may not fit well. Then the
system becomes unsteady,
tends to hang up easily or even
results in boot failure. Use
another VGA card instead when
any of the above-mentioned
conditions happens.

E. DRAM, EDO RAM Installation Procedures:
 Change nothing if EDO RAM is used. BIOS automatically detects the
RAM type.
 With 586 CPUs, two FPM/EDO RAM Modules are required on SIMM
sockets to compose a bank for the system to start.
 In VIA VPX chipset, SIMM and DIMM RAM are able to co-work.
 MEMO for Installing Syatem:
⊕ Concerning memory setup, you can find how to from “Chipset
Frature Setup” under BIOS setup. However, to avoid system unstable
or system hang, user without engineering background is not suggested
to change BIOS set up.
⊕ If system boot failure, please clean SIMM socket (with clean oil) or
polish Gold-Finger of DRAM with soft eraser, and try again.
 SIMM Socket output voltage is
5V, expandable to 512MB.
 Support 5V Fast Page Mode/
Extended Data Out RAM.
 The BIOS DRAM default setting
is 70 ns. Change the BIOS
“Chipset Feature Setup” default
setting to 60ns for better
performance, if the chipset is
marked 60ns.

F. SDRAM, Cache Memory Installation Procedures:
 The Dual Inline Memory Module (DIMM) must be 3.3 Volt and
Unbuffered Synchronus DRAM (SDRAM) 8MB, 16MB, 32MB or 64MB.
The following illustration shows the type of DIMM Module.
168-PIN SDRAM DIMM Notch Key Definitions
 Default setting: 3.3V.(Only)
 First, verify the working voltage of
the EDO/SDRAM module in either
DIMM socket (DIMM1 or
DIMM2-table free).
 You can set up the BIOS “Chipset
Feature Setup” to the best working
condition basing on the type of
EDO/SDRAM you are using.

G. Other Jumper Settings
POWER SW (FOR ATX POWER SUPPLY):
The button should be a momentary switch that is normally open.
Pushing the ATX Power Switch will immediately change the system
status. Before or during “POST”, you need to hold the button for four
seconds in order to turn off the system.
 JP5: Clear CMOS
Turn off the system and short pins 2-3 (J3) to clear CMOS. Then short
pins 1-2 before turning it on. You may damage the chipset if you power
on the system by shorting pins 2-3.
JP5
1-2 Normal operation(Default).
2-3 for clearing CMOS Data.
 CPU Cooler Fan connector
This is the connector for CPU cooler. Never use the jumper to short the
connector. Serious damages caused this way will not be warrantied.

Power LED & Keylock:
Keyboard lock switch and
Power LED connector.
 Speaker:
Connect to the system’s
speaker for beeping.
 Reset:
Short to restart system.
 HDD LED:
LED ON when on board PCI
IDE hard disk activates.
 SMI SW:
Short to enter sleep mode. A
keystroke or mouse movement
(mouse driver exits) will instantly
“wake up” the system.
