How To Use This Manual 6241 Mainboard
HOW TO USE THIS MANUAL
This manual is written in a user-friendly style. It would e
advisa le for users to read it in an orderly sequence :
1. For Hardware Information:
Read Page A: COMPONENT LOCATION DIAGRAM, Page B: CHECK LIST
OF THE PACKAGING and Page C: CONNECTORS AND JUMPERS
DESCRIPTION.
2. For Mainboard and System Feat res:
Read “Chapter 1 Introd ction” in detail, and you will find helpful information on
mainboard and system features. Especially, when you want to do some feature setup,
detailed instructions are provided therein to help you through.
3. For CPU, Memory and Drivers Installation:
Read “Chapter 2 Installation” for your CPU, memory and application drivers
installation. Detailed instructions are provided to guide all kinds of users.
4. For BIOS Update and Set p:
Read “Chapter 3 Award BIOS Set p” for updating your mainboard BIOS and
setting up your BIOS Configuration.
5. For Installing Penti m II/III, Celeron or Processors with SECC2 Package:
Read APPENDIX A for setting up Intel PentiumIII, PentiumII, CeleronTM, or
processors with SECC2 package.
6. For Installing Thermister:
Read APPENDIX B for thermister installation. You will find that the self-
explanatory drawings enclosed therein make the job easy and simple..
7. For other Technical S pport:
Read APPENDIX C , fill and send the Request Form to your dealer for other
technical support.
It is often heard that the default setting on a mainboard is not what user expects. A
user-friendly manual would be the handiest assistant to help change the on-board
configuration or default setting. In case this manual cannot solve all your problems,
please ask your dealer for help and be sure the warranty on your system is still valid.

Chapter 1 Introduction 6241 Mainboard
1-2 Software Power Off Control
6241 Mainboard design supports Software Power Off Control feature through the
SMM code in the BIOS under Windows 95/98, and MS-DOS operation system
environment. This is Intel ATX form factor feature and you should use ATX power
supply.
First, you should connect the power switch cable to the connector “PS-ON” on the
mainboard. In the BIOS screen of POWER MANAGEMENT SETUP’, choose “User
Defined” (or “Min. Power Saving” or “Max. Power Saving”) in ‘Power Manager’ and
pick up “Yes” in ‘PM Control by APM’.
In Windows 95/98, if you would like to power off the system, you just need to
choose “shutdown the computer ?” in the “Shut Down Windows“ from Windows
95/98. Then the system power will be off directly, and become to the stand-by status.
If you would like to restart the system, just press the power switch button, and the
system will be powered on.
Note : If yo are going to leave yo r system idle for several days, we s ggest yo
se hardware power off to sh tdown yo r system.

* Under Software power off control, the status of Power LED Light depends on the setting of JP5.
If you set JP5 to “pin1-2” position, it is blinking. Otherwise, it is light off.
1-3 Fan Off Control
With fan-off function, the CPU cooling fan can turn off automatically even when
the system is in suspend mode. This function is able to reduce energy consumption
and system noise.
Because it is a feature of advanced BIOS, you should set this option enabled
through “Power Management Setup” from the BIOS setup screen. ( An ATX power
s pply is needed to achieve this f nction.)

6241 Mainboard Chapter 1 Introduction
1-4 R nning 100 MHz CPU B s on mainboard (JP11)
The mainboard provides J mper 11 that allows you to set your CPU host clock and
perform CPU overclock function. There are two ways to set CPU host clock at
‘closed’ and ‘open’. When setting ‘closed’, the system will automatically detect the
CPU host clock, for instance 66MH and 100MH . Another way is to set J mper 11
at ‘open’ for 66MH CPU overclock to 100MH .
We recommend that users should use Intel PentiumII/III 100 MH CPU, running at
350, 400, 450 and 500MH internal clock speed. Moreover, the SDRAM memory
module must be 8 nano-second (Maximum Frequency 125 MH ) speed of memory –
die or less. However, based on Intel’s design, we don’t recommend users to run over
100MH CPU host bus.
Please note that the defa lt setting of J mper 11 is ‘closed’.

If yo wo ld like to r n over 100MHz CPU host b s, like 112 and 124MHz,
please set “CPU Host Clock” in “CHIPSET FEATURES SETUP” from the
BIOS set p screen. If the system can’t boot p at CPU freq ency that has
been set, yo can press the ‘Insert” key to clear p the set freq ency. After
restarting the system, it will operate at the defa lt freq ency.
