C. Note to Installing the Mainboard

Touch the non-coated area on the computer case or use a grounded wire to release static electricity before you open the anti-static electricity bag and take out the mainboard. It's likely to damage the mainboard components while taking out the board without first releasing static electricity. During installation, avoid touching the components on the mainboard.

Dear Customers: Thank you for your patronage of our products. The board you bought is a jumper-less mainboard. The ratio and frequency of the CPU shall be set in BIOS and the working voltage for the CPU shall be automatically detected. Please read carefully the following instructions:

1. Power on the installed system and press the "DEL" key to enter BIOS

Page 5

TM-P2EXAT User’s Manual

Setup. Select "Chipset Features Setup" and press <Enter>.

2. Select "CPU Speed" and press "PgUp" or "PgDn" to set the CPU ratio and frequency. The available options are : Intel PII 233MHz (66X3.5), 266MHz (66X4), 300MHz (66X4.5), 333MHz (66X5), 366MHz (66X5.5) and "Manual".

To set the CPU manually, please note the following:

CPU Speed: "Manual" (you can manually set the CPU ratio and frequency) CPU Ratios: x3.5, x4, x4.5, x5, x5.5 CPU Frequency: 50MHz, 60MHz, 66MHz, 68MHz, 75MHz, 83MHz

Several options are provided for the CPU external clock. You are recommended to restore to the default setting in case of instability when the external clock exceeds 66MHz.

NOTE: System failure may occur if the CPU frequency is set incorrectly. To solve this problem. Press the "Insert" key on the keyboard to clear the previously set frequency (i. c., restore the default frequency), and then reboot the system.

 Switch voltage is applied, making the temperature lower and voltage

steadier.

 You don’t need to adjust Voltage in Pentium II mainboard. It will

automatically send out one VID(Voltage Identification) to the mainboard power supply to ask for the voltage it needs.

 The CPU type default setting is Intel Pentium II 266MHz=66 MHz＊4.

Page 6

TM-P2EXAT User’s Manual

E. EDO/ SDRAM Installation Procedures:

 A 168-pin DIMM can support up to 256MB 3.3V EDO/ SDRAM.

 Default setting: 3.3V. (Only)

 To avoid compatibility and reliability problems, you are recommended to

test the 168-pin SDRAMs before buying them since the PCB specifications differ.

 First, verify the working voltage of the EDO/ SDRAM module in either

DIMM socket.

 P2EXAT only supports 3.3V EDO/ SDRAM module. The following

illustration shows you the difference between 3.3V and 5V to ensure your correct selection of 3.3V DIMM module for using.

 You can set up the BIOS “Chipset Feature Setup” to the best working

condition basing on the type of EDO/ SDRAM you are using.

 The BIOS DRAM default setting is 60 ns. Change the BIOS “Chipset

Page 7

TM-P2EXAT User’s Manual

Feature Setup” default setting to 50ns for better performance, if the chipset is marked 50ns.

 Change nothing if EDO RAM is used. BIOS automatically detects the

RAM type.

 MEMO for Installing System:

⊕ Concerning memory setup, you can find how to from “Chipset Feature 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 DIMM socket (with clean oil) or polish Gold-Finger of DRAM with soft eraser, and try again.

 The Dual Inline Memory Module (DIMM) must be 3.3 Volt and

Unbuffered Synchronous DRAM (SDRAM) 8MB, 16MB, 32MB or 64MB. The following illustration shows the type of DIMM Module.

 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.

 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.

 J25: Clear CMOS

Turn off the system and short pins 2-3 to clear CMOS. Then short pins 1-2 before turning it on.

J25 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.

 Creative SB-Link

It is used to connect the AWE64 or other compatible sound cards so that they are made compatible with the ISA-compatible SB16 sound cards.

G. Note to BIOS Update

Do not update the BIOS if no abnormalities occur. However, if BIOS update is needed, consult your dealer first. Prior to updating your BIOS, you are recommended to save the original BIOS values.

1. Download the AWARD BIOS Flash Utility file (Awdflash.exe)

2. Download the BIOS file used by your mainboard(e.g., EXV110N.BIN)

Page 9

TM-P2EXAT User’s Manual

3. Reboot your system (but do not run Himem.sys and Emm386.exe) to execute the new BIOS program.

4. Execute these commands: Awdflash EXV110N.BIN

5. When this message displays: "Do you want to save BIOS (Y/N)?" Type "N"

6. When this message displays: "Are you sure to program (Y/N)?" Type "Y"

7. Turn off power to your system to clear the CMOS data.

8. Turn on the power to test if your system is running normal.

H. Keyboard/ PS/2 Mouse Power On and MODEM Ring on

 To make sure the 5VSB signal nearly to 750mA (Amperage) from

ATX Power Supply, or if your keyboard consuming power than 300mA, it's better to upgrade your ATX Power Supply to 1A for working perfectly.

 If you are going to use the function of keyboard and PS/2 mouse

power on, then, the power-switch will be becoming useless automatically (unable to be used).

I. System Health Monitor

Page 12

TM-P2EXAT User’s Manual

 Fan Monitoring:

There are two fan connectors, one is for CPU, the other can be a housing fan. When the fans speed is working abnormal, there will be warning (Speaker Alarm) through application software such as SM10(Small Icon for System Monitoring) to notify user. The fan monitoring function is implemented by connecting fan to 3-pin fan connector FAN1/ FAN2 and installing SM10. Referring to Page 12 (System Health Monitor).

 CPU Thermal Protection:

TM-P2EXAT implements special thermal protection circuits. When temperature is higher than a predefined value, there will be warning

(Speaker Alarm) through application software such as SM10 (Small Icon

for System Monitor) to notify user. It's automatically implemented by BIOS or SMD10, no hardware installation is needed. Referring to Page12 (System Health Monitor).

Page 13

TM-P2EXAT User’s Manual

This mainboard also reserves an option to use special CPU cooling Fan. With Thermal Sensor on it. The CPU thermal sensor should be connected to J16.

 System Voltage Monitoring:

TM-P2EX is featured with a voltage monitoring system. When you turn on your system, this smart design will keep on monitoring your system working voltage. If any of voltage is over the component's standard, there will be Speaker Alarm though application software SM10 (Small Icon For System Monitor) for a warning to user. System voltage monitoring function monitors 5V, 12V, 3.3V and CPU voltage. It's automatically implemented by BIOS and SM10, no hardware installation is needed.
