Suspend To RAM Installation

Suspend to RAM Installat i on

A.1 Introduce STR function:

Suspend-to-RAM (STR) is a Wi ndows 98 A CPI s leep mode function. When recovering f rom

STR (S3) sleep mode, the system is able to retrieve the last “state” of the system before it
went to sleep and recover to that sta te in just a few sec onds. The “state” i s stored in memory
(RAM) before the system goes to sleep. During STR sleep mode, the 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)
C. After setup completes, remove the CD, and reboot your system
(This manual assumes that your CD-ROM device drive letter is D:).

“D:\setup”

in the window provided. Hit the enter key or click OK.

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.

29

Suspend to RAM Installat i on

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

D. 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 “Resume by Alarm” function.

3. Use the “Modem Ring On” function.

4. Use the “Wake On LAN” function.

5. Use the “USB Device Wake Up” function.

6. Use the “KB/MS Wake up from S3” function.

DDR Introduction

DDR Introduction

Established on the existing SDRAM industry infrastructure, DDR (Double Data Rate)
memory is a high performance and cost-effective solution that allows easy adoption for
memory vendors, OEMs and system integrators.

DDR memory is a sensible evolutionary solution for the PC industry that builds on the
existing SDRAM infrastructure, yet makes awesome advances in solving the system
performance bottleneck by doubling the memory bandwidth. DDR SDRAM will offer a
superior solution and migration path from existing SDRAM designs due to its
availability, pricing and overall market support. PC1600 DDR memory (DDR200)
doubles the data rate through reading and writing at both the rising and falling edge of
the clock, achieving data bandwidth 2X greater than PC100 when running with the
same DRAM clock frequency. With peak bandwidth of 1.6GB per second, DDR
memory enables system OEMs to build high performance and low latency DRAM
subsystems that are suitable for servers, workstations, high-end PC’s and value
desktop SMA systems. With a core voltage of only 2.5 Volts compared to conventional
SDRAM's 3.3 volts, DDR memory is a compelling solution for small form factor
desktops and notebook applications.

@BIOS™ Introduction

Gigabyte announces
Windows BIOS live update utility

Maybe not like others, you are very experienced in BIOS updating and spend quite
a lot of time to do it. But of course you don’t like to do it too much. First, download
different BIOS from website and then switch the operating system to DOS mode.
Secondly, use different flash utility to update BIOS. The above process is not a
interesting job. Besides, always be carefully to store the BIOS source code correctly in
your disks as if you update the wrong BIOS, it will be a nightmare.

Certainly, you wonder why motherboard vendors could not just do something right
to save your time and effort and save you from the lousy BIOS updating work? Here it

comes! Now Gigabyte announces @BIOS
This is a smart BIOS update software. It could help you to download the BIOS from
internet and update it. Not like the other BIOS update software, it’s a Windows utility.

With the help of “@BIOS

BIOS from the nearest Gigabyte ftp site automatically. There are several different
choices; you could use “Internet Update” to download and update your BIOS directly.
Or you may want to keep a backup for your current BIOS, just choose “Save Current

BIOS” to save it first. You make a wise choice to use Gigabyte, and @BIOS
your BIOS smartly. You are now worry free from updating wrong BIOS, and capable to
maintain and manage your BIOS easily. Again, Gigabyte’s innovative product erects a
milestone in mainboard industries.

For such a wonderful software, how much it costs? Impossible! It’s free! Now, if you
buy a Gigabyte’s motherboard, you could find this amazing software in the attached
driver CD. But please remember, connected to internet at first, then you could have a

Windows overdrive utilit y

“Overdrive” might be one of the most
common issues in computer field. But have
many users ever tried it? The answer is
probably “no”. Because “overdrive” is thought to
be very difficult and includes a lot of technical
know-how, sometimes “overdrive” is even
considered as special skills found only in some
enthusiasts.

But as to the experts in “overdrive”, what’s the truth? They may spend quite a lot
of time and money to study, try and use many different hardware and software tools
to do “overdrive”. And even with these technologies, they still learn that it’s quite a
risk because the safety and stability of an “overdrive“ system is unknown.

Now everything is different because of a Windows overdrive utility
EasyTune

rule of “overdrive”. This is the first overdrive utility suitable for both normal and power
users. Users can choose either “Easy Mode” or “Advanced Mode” to run “overdrive”
at their convenience. For users who choose “Easy Mode”, they just need to click
“Auto Optimize” to have auto and immediate CPU overclocking. This software will
then overdrive CPU speed automatically with the result being shown in the control
panel. If someone prefers to “overdrive” by oneself, there is also another choice.
Click “Advanced Mode” to enjoy “sport drive” class overclocking. In “Advanced
Mode”, one can change the system bus speed in small increments to get ultimate
system performance. And no matter which mainboard is used, if it’s a Gigabyte’s

product*, EasyTune

Besides, different from other traditional over-clocking methods, EasyTune
doesn’t require users to change neither BIOS nor hardware switch/ jumper setting;
on the other hand, they can do “overdrive” at only one click. Therefore, this is a safer
way for “overdrive” as nothing is changed on software or hardware. If user runs

EasyTune
again and the side effect is then well controlled. Moreover, if one well-performed

system speed been tested in EasyTune
“Load” it in next time. Obviously, Gigabyte EasyTune
