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 you are going to leave your system idle for several days, we suggest you
use hardware power off to shutdown your 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
supply is needed to achieve this function.)
