 The CPU voltage default

setting is 3.30V(for Intel
P54C), and
J7=On(Short), J8=Off(Open).

 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 the CPU makers,
to make any CPU applied work
with the best performance.

 Set the V I/O and Vcore to the

same voltage, if you use a
single voltage CPU.

 The CPU type default setting is

＊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.

 SIMM Socket output voltage is

5V, expandable to 256MB.

 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

 Sync SRAM (Pipeline Burst SRAM) If Sync SRAM Modules are

installed, they consists of Pipeline Burst 2 PCs 32K x 32-6 for 256KB or
2 PCs 64Kx32-6) for 512KB Sync SRAM.

 A 168-pin DIMM can support up to

128MB EDO/SDRAM.

 Default setting: 3.3V.

 First, verify the working voltage of

the EDO/SDRAM module in either
DIMM socket (DIMM1 or DIMM2­table 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

 Speaker:

Connect to the system’s speaker for beeping.

 Keylock:

Keyboard lock switch and Power LED connector.

 Reset:

Short to restart system.

 HDD LED:

LED ON when on board PCI IDE hard disk activates.

 SMI LED:

LED ON when system is in any Saving mode.

 Keyboard Power On/Off Function (Patent Is Under Application!!!)

1.Turn on the system by pressing the “Ctrl-***” keys simultaneously
(Strike the “*” key 3 times while holding the “Ctrl” key.)

2. Press “Ctrl-***” again to turn off the system. This function becomes
invalid during POST (Power-On-Self-Test).

3. CPU Fan Auto Turn Off: The CPU fan automatically turns off when
the
system enters the Suspend state. Remember to connect the CPU fan

8

TM-586 TX3 User’s Manual

to its connector on the mainboard to enable this function.

 SMI SW:

Short to enter sleep mode. A keystroke or mouse movement (mouse
driver exits) will instantly “wake up” the system.

 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.

 J3: 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.

J3
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.

 Modem Ring On Function Operation: (Only available by using ATX

Power Supply)

1. Enter BIOS setup.

2. Select Power Management Setup.

3. Resume by Ring: Enable.

4. Save BIOS setup and Reboot.

5. Booting from DOS, Windows, or Windows 95.

6. Turn off the system by:
a. ATX-Power Switch
b. Keyboard Power On/Off
c. Windows 95 Software Power Off

7. System Waiting for Modem Ring On
When Modem Ringing Signal Active, System will wake-up.
