1-2 Software Power Off Control
The 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.
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 Define” (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.
Status Power LED Light Turbo LED Light
Software power off
control Blinking (JP5, pin1-2) Light off (JP5, pin2-3) Light off
APM mode Light on Light on
System running Light on Light on
* 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.

1-4 Running 100 MHz CPU Bus (with JP11)
The mainboard provides Jumper 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 66MHz and 100MHz. Another way is to set Jumper11at
‘open’ for 66MHz CPU overclock to 100MHz.
We recommend that users should use Intel PentiumII/III 100 MHz CPU, running
at 350, 400, 450 and 500MHz internal clock speed. Moreover, the SDRAM memory
module must be 8 nano-second (Maximum Frequency 125 MHz) speed of
memory –die or less. However, based on Intel’s design, we don’t recommend users to
run over 100MHz CPU host bus.
Please note that the default setting of Jumper 11 is ‘closed’.

1-5 Keyboard & PS/2 Mouse Power On (with JP9)
With ATX Power Supply and Jumper 9 set to Pin 1-2 closed, 6254M Mainboard
is enabled to Keyboard & PS/2 Mouse Power On functions :
JP 9 KB & PS/2 Mouse Wakeup
1-2Enable
2-3Disable
(a) Enable (1-2 closed) (b) Disable (2-3 closed)
The default Power On function is “Button Only”. That means, we can only turn
our computer on and off by pressing the “Power Button”. If we want to enable KB &
PS/2 Mouse Power On function, we first have to set JP9 to Pin 1-2 closed, and then go
to “Power On Function” in “Integrated Peripherals” of Award BIOS Setup. At the line
“Power On Function”, we can press “Page Up” or Page Down” to make the following
selections:
1. Password(via Keyboard):
When user selects “Password”, it will show “Enter Password:”. After user has typed
the password, screen will show “ Confirm Password:” and user has to type the same
password to confirm it. Save selection and shut down system. Now computer will
only be powered on by entering correct password.
In case the set password is forgotten, carry out “Clear CMOS” (Page 14) to clear
password, or computer can not be powered on.
2. Hot Key (via Keyboard):
When user selects this option, screen will show another line : “Hot Key Power ON :
Ctrl-F1”. User can select from “Ctrl-F1” to “Ctrl-F12” as Hot Key by pressing
PageUp / PageDown. After fixing Hot Key, save selection and shut down system.
Now computer will only be powered on by pressing the correct Hot Key.
3. Mouse Left, Mouse Right (via PS/2 Mouse):
This function is available via PS/2 mouse only. User can select either “Mouse Left”
or “Mouse Right” from the “Power On Function” line. After picking either option,
save selection and shut down system. Now computer will only be powered on by
double-clicking the correct PS/2 Mouse button.
Do not slide the mouse when you click; or you can’t power on the system.
4. Button Only (via Power Button): “Button Only” is default setting, at which
computer can only be on/off via Power Button.

1-6 Wake-On-LAN
The remote Wake-On-LAN (WOL) mode of operation is a mechanism that uses
Advanced Micro Device Magic Packet technology to power on a sleeping workstation
on the network. This mechanism is accomplished when the LAN card receives a
specific packet of information, called a Magic Packet, addressed to the node on the
network. For additional protection, Secure ON is an optional security feature that can
be added to the Magic Packet that requires a password to power on the sleeping
workstation. When LAN card is in remote Wake-On-LAN mode, main system power
can be shut down leaving power only for the LAN card and auxiliary power
recondition.
The LAN card performs no network activities while in the remote Wake-On-LAN
mode of operation. It only monitors the network for receipt of a Magic Packet. If a
Magic Packet is addressed to the LAN card on the network, the LAN card wake up the
system. If the Secure ON feature has been enabled, the password added to the Magic
Packet is also verified prior to waking up the system.
You should select two kinds of PCI Ethernet cards with WOL function. One is
Intel and the other is with PME signal supporting. And you can set “Wake Up On
LAN” this function enabled through “ Power Management Setup” from the BIOS setup
screen.
1-7 Thermister (optional)
If Hardware Monitor is built onboard, CPU temperature can be monitored by
setting up the Thermister.
When setting up the thermister (refer to Appendix B), the BIOS will load the CPU
temperature automatically. A warning beep sound will be sent out if the user set the
option on. If the CPU is overheated, the user will get the warning. Then you should
shut down computer and check your devices. Or contact you dealer for further help if
CPU temperature persists.
Note: If you would like to enable the function of hardware monitor, to set up
thermister beforehand is necessary. RT2 is the thermister connector.

1-8 LDCM 
LANDesk Client Manager (optional)
The mainboard built-in controller supports Intel LDCM. LDCM can satisfy users
who want manageable systems that can interact automatically with the user. Client
manager is the answer, enabling both administrators and clients to manage systems.
The features of LDCM are as following :
View system inventory
Client Manager enables you to view hundreds of inventoried items. Some of these
items are software related, while many others are hardware related.
View DMI-compliant component information
Client manager enables you to view component information that is compliant with the
Desktop Manager InterfaceDMI. This means you can manage third-party
DMI-compliant components which did not include Client manager.
Back up and restore system configuration files.
Client Manager enables you back up and restore system configuration files. Whenever
you plan on changing the system configuration , you can make a backup set. If the
system no longer works correctly, after you the change the system configuration ,
you can simply restore the system configuration with the backup set.
Troubleshoot
Since Client manager enables you to view the system inventory, you can easily
troubleshoot system problems.
Receive notifications for system events
Client manager enables you to receive notification of certain system events. For
example, if the system is running low on virtual memory, you are notified of the
potential problem.
Transfer files to and from client workstations
As an administrator, you have the ability to transfer files to and from client workstation.
This is helpful, for example, when you need to update a client workstation driver.
Remotely reboot client workstations
Administrator also have the ability to remotely reboot a workstation. This is helpful
when you want your system configuration changes to take effect.

DRAM type, size, parity supported:
6EDO DRAM: for 66MHz system frequency only
6Unbuffered, registered SDRAM with SPD
6Both parity or non-parity are available.
63.3V, Single/double-side, 8/16/32/64/128/256Mbytes
(Max. memory size: 256MB registered SDRAM or EDO DRAM)
6Both 4Mbx4 and 16Mbx4 (Each side has 16 chips.) SDRAM devices are
supported in the form of Registered DIMMs only.
uFor 66MHz host bus CPUs use 12ns or faster DIMM module;
uFor 100MHz host bus CPUs use 10ns or faster and PC-100 compliant modules .
@@ SPD (Serial Presence Detect)
This EPROM contains speed and design information of the memory module. The
mainboard may get optimal performance via accessing the data of SPD.
@@ ECC (Error Check and Correction)
This mainboard can support the ECC function while utilizing parity modules. To enable
this function, users must set “DRAM Data Integrity Mode”to “ECC”through “Chipset
Features Setup”from the BIOS setup screen. All in all, ECC’s function is to detect and
correct the errors of transfer data.

CHAPTER 3 AWARD BIOS SETUP
Award BIOS manufacturer provides access to the system BIOS through the hardware
and software on the mainboard. The hardware consists of a Flash ROM and the
software is a group of programs that are installed in the ROMBIOS along with all the
other data the BIOS must contain.
After the BIOS is updated, if you want to clear the old setup data stored in the CMOS,
then you can clear CMOS.
NOTE : In case CMOS should be cleared, unplug the power cord, set Jumper 8 2-3
closed for at least 5 seconds, put it back to 1-2 position and plug the power cord
again.
