Chapter 1 Introduction 6254M Mainboard

1-2 Softwa re 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)

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.

6254M Mainboard Chapter 1 Introduction

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 Jumper 1 1 at ‘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’.

Jumper 11 BASE CLK Closed Auto (default) Open Overclock (66MHz àà 100MHz)

(a) Pin Closed (b) Pin Open

Slot 1

JP11

--If you would like to run over 100MHz CPU host bus, like 112 and 124MHz, please

set “CPU Clock Frequency” in “CHIPSET FEATURES SETUP” from the BIOS setup screen. If the system can’t boot up with the clock frequency that you set to, you can clear the set frequency by pressing the ‘Insert” key on keyboard. After restarting the system, you have the system operating at the default frequency.

Chapter 1 Introduction 6254M Mainboard

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

1-2 Enable 2-3 Disable

(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 us er 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 Rig ht (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.

6254M Mainboard Chapter 1 Introduction

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.

Chapter 1 Introduction 6254M Mainboard

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 clie nt workstation driver.



3-1-1 UPDATE MICROCODE API

Intel also provides MICROCODE API(Applications Programming Interface) for PentiumII/III processor-based mainboard user to update data block in BIOS quickly and easily. (You can find this utility in the All-In-One CD in the mainboard package).

The BIOS code on the PentiumII/III processor-based mainboards contains data that is specific to each silicon stepping of the processor. Integrators must ensure that this BIOS stepping data matches the used processor stepping. When the BIOS does not contain stepping data that matches the processor stepping, in tegrators must update the data in the BIOS before shipping the system. Historically, PentiumII/III systems have been updated by replacing the entire BIOS with a new revision of BIOS that contains the correct stepping data.

Intel‘s BIOS update API allows just the stepping data within the BIOS to be updated as needed. Mainboards that contain a BIOS with the Intel-defined BIOS update API can be quickly and easily updated, if required, without obtaining a complete BIOS upgrade. Using this utility, integrators can easily verify that the correct stepping data is present in all PentiumII/III processor-based mainboards. However, if the stepping data requires to be updated, the mainboard BIOS must contain the Intel -defined BIOS update API, otherwise a complete BIOS upgrade is required from the mainboard vendor.

Since API program can only be executed under DOS Real Mode, you must enter

Real Mode first and load the API program to Drive C.

To load the program to C by following steps:

(1) Type “ md c:\ api ” and press Enter. Directory “api” is made in Drive C now. (2) Insert the Driver/Utility CD into CD ROM Drive E. (3) Then type “ copy e:\api\*.* c:\api ” and press Enter.

(API program is loaded to Drive C now.)

(4) Type “ C:\ api \checkup ” to execute this program.

The main menu should now be displayed with the following four options :

1) Check and load update

2) Specify stepping data file [current : pep.pdb]

3) Help

4) Quit without loading update

Select 1 to know the stepping filename, select 2 to load right patch code, then select 1 to update proper patch code. Now, the screen will show the message “please remove the CD from CD-ROM drive”. Then cold boot (mechanical power off) system

to continue. For more information, please refer to “CHECKUP.HLP“ file.
