CPU Speed Setup

The system bus frequency can be switched between 66MHz and 133MHz by adjusting JP17 &
JP10. The CPU Frequency is control by BIOS.

M

The CPU speed must match with the frequency RATIO. It will cause system hanging up

if the frequency RATIO is higher than that of CPU.

«Note: Please set the CPU host frequency in accordance with your processor’s
specifications. We don’t recommend you to set the system bus frequency over
the CPU’s specification because these specific bus frequencies are not the
standard specifications for CPU, chipset and most of the peripherals. Whether
your system can run under these specific bus frequencies properly will depend
on your hardware configurations, including CPU, Chipsets, SDRAM,
Cards….etc.

«Note: JP17 is only available when the mother board use 82810E chipset.

Suspend to RAM Installation

A.1 Introduce STR function:

Suspend-to-RAM (STR) is a Windows 98 ACPI sleep mode function. When
recovering from STR (S3) sleep mode, the system is able, in just a few
seconds, to retrieve the last “state” of the system before it went to sleep and
recover to that state. The “state” is stored in memory (RAM) before the
system goes to sleep. During STR sleep mode, your system uses only
enough energy to maintain critical information and system functions,
primarily the system state and the ability to recognize various “wake up”
triggers or signals, respectively.

A.2 STR function Installation

Please use the following steps to complete the STR function installation.

Step-By-Step Setup

Step 1:

To utilize the STR function, the system must be in Windows 98 ACPI mode.

Putting Windows 98 into ACPI mode is fairly easy.

Setup with Windows 98 CD:

A. Insert the Windows 98 CD into your CD-ROM drive, select Start, and then Run.
B. Type (without quotes) “D:\setup /p j” in the window provided. Hit the enter key or click

OK.
C. After setup completes, remove the CD, and reboot your system
(This manual assumes that your CD-ROM device drive letter is D:).

31

Suspend to RAM installation

Step 2:

(If you want to use STR Function, please set jumper JP11 (Closed.)

Pin No. Definition

Open STR Disabled

(Default)

Close STR Enabled

Step 3:

Power on the computer and as soon as memory counting starts, press <Del>. You will enter
BIOS Setup. Select the item “POWER MANAGEMENT SETUP”, then select “ACPI Suspend
Type: S3 (Suspend to RAM)”. Remember to save the settings by pressing "ESC" and choose
the “SAVE & EXIT SETUP” option.

Congratulation! You have completed the installation and now can use the STR function.

32

6WMM Series Motherboard

A.3 How to put your system into STR mode?

There are two ways to accomplish this:

1. Choose the “Stand by” item in the “Shut Down Windows” area.

A. Press the “Start” button and then select “Shut Down”

B. Choose the “Stand by” item and press “OK”

33

Suspend to RAM installation

2. Define the system ”power on” button to initiate STR sleep mode:

A. Double click “My Computer” and then “Control Panel”

B. Double click the “ Power Management” item.

34

6WMM Series Motherboard

C. Select the “Advanced” tab and “Standby” mode in Power Buttons.

Step 4:

Restart your computer to complete setup.
Now when you want to enter STR sleep mode, just momentarily press the “Power on” button..

A.4 How to recover from the STR sleep mode?

There are six ways to “wake up” the system:

1. Press the “Power On” button.

2. Use the “Keyboard Power On” function.

3. Use the “Mouse Power On” function.

4. Use the “Resume by Alarm” function.

5. Use the “Modem Ring On” function.

6. Use the “Wake On LAN” function.

35

A.5 Notices :

1. In order for STR to function properly, several hardware and software requirements must be

satisfied:

A. Your ATX power supply must comply with the ATX 2.01 specification (provide more than

720 mA 5V Stand-By current).

B. Your SDRAM must be PC-100 compliant.

2. Jumper JP2 is provided to connect to the STR LED in your system chassis. [Your chassis
may not provide this feature.] The STR LED will be illuminated when your system is in STR
sleep mode.

Memory Installation

The motherboard has 2 dual inline memory module (DIMM) sockets. The BIOS will automatically
detects memory type and size. To install the memory module, just push it vertically into the DIMM
Slot .The DIMM module can only fit in one direction due to the two notch. Memory size can vary
between sockets.

Install memory in any combination table:
